How To Change Geometry Color Of An Imported Drawing In Mastercamm
Managing Geometry
Merge Geometry
Rhino (and other CAD) files are imported by selecting File > Merge. This volition insert the geometry from the selected CAD file into current MasterCAM file, keeping the aforementioned units and origin from the CAD file. Merges are cumulative, and can be performed at whatever time.
After the initial merge, later on merged geometry will exist added to the active level by default. Users may specify to instead merge additional geometry onto the originally assigned level by ticking the radio button for "Merged File Levels" during the merge procedure.
Select Geometry
MasterCAM breaks apart meshes and polysurfaces into their constituent faces and bondage into theirconstituent segments. The subdivided geometry may exist selected piecemeal, or en masse via window selection. Selected geometry turns yellowish. Geometry continues to be added to the selection without holding downwardly shift or some other primal. Todeselect geometry, click on it a second time, or printing the ESC key to deselect all. The Level Manager can be used to simplify geometry choice by altering the visibility of diverse levels.
Motility Geometry
Choose "Transform" from the ribbon. Selected geometry can now exist manipulated by choosing the desired transformation (Translate, Rotate, Mirror, etc) from the ribbon. Change the Method from Copy to Movement, next input the increment of the transformation (units XYZ, degrees, etc). Geometry that undergoes a transformation within MasterCAM will retain its operation assignments, all the same, the operations will get dirty and require regeneration.
Snapping
MasterCAM has express object snapping capabilities as compared with Rhino. This can make complex geometry transformations a chore inside MasterCAM. Often it may be easier to delete the MasterCAM geometry, perform the desired transformation within Rhino, and merge the relocated geometry back into MasterCAM. This will require the reassignment of any toolpaths that referenced the deleted geometry.
Delete Geometry
Press F5 or DEL to delete selected geometry. If the geometry is included in a toolpath, a dialog box volition appear to warn you. To go on, choose "Delete all selected entities". The selected geometry will then be deleted. Previously associated toolpaths volition remain, but will no longer work (they are now "dirty").
Visibility
Default MasterCAM view is Shaded. Toggle Wireframe past pressing ALT+S, or choosing View from the ribbon and selecting Wireframe. This will change selectable geometry.Toggle Ghosted brandish by pressing CTRL+T, or choosing View from the ribbon and selecting Translucency. This will non change selectable geometry. Toggle unselected geometry (testify/hide) by pressing ALT+E.
Managing Levels
Layers vs. Levels
MasterCAM geometry can be organized into Levels, which are analogous to Rhino Layers. As with Rhino Layers, Levels may be shown or hidden selectively to let for easier geometry selection or to subtract visual clutter. Rhino layers will exist imported every bit levels, and the associated geometry will maintain its layer-assigned color. MasterCAM does non use a nested hierarchy for levels, so this arrangement will be lost when importing from Rhino.
Layer Colors
MasterCAM uses Yellow to bespeak geometry selections, and volition not display edges for geometry whose Rhino Layer colour is Black. And then, it is best to avoid using black or yellow for all Rhinoceros layers with geometry prior to merging.
Level Manager
The Level Manager is accessed from Managers pane (defaults to left side of window). Select the Levels tab at the bottom of the pane to encounter the currently defined levels. The Active Level is designated past a greenish check mark, and cannot be hidden by default. Click adjacent to a different level's number to make it active instead. Show or Hide levels by clicking the X in the Visible column. Employ levels for easy geometry pick by right clicking the desired level'south row and choosing Select All Entities.
Managing Planes
WCS + Tplane + Cplane
Each operation generates toolpaths according to the Piece of work Coordinate Organisation (WCS), Tool Airplane (Tplane), and Construction Plane (Cplane) that is specified in its parameters. The currently specified planes are also visible in the Toolpath Manager alongside the functioning name. The WCS, Tplane, and Cplane should always friction match for any given functioning.
Airplane Manager
The Plane Manager allows users to view, create, alter, and delete planes. These planes are referenced by operations in guild to describe toolpaths.
Creating a Airplane
In some cases, the default planes may not be appropriate for an operation. For case, the flipped side of a two-sided milling job cannot reference the default Top plane, so a new plane must be created. The most straightforward method is to duplicate an existing aeroplane whose axes are in the preferred orientation, so enter new origin coordinates for the duplicate airplane.
Managing Operations
What is a Toolpath?
A toolpath is the path through space that the tip of a cut tool follows on its way to producing the desired geometry of the workpiece. In MasterCAM, toolpaths are represented past bluish and yellowish lines that are drawn across the surface of your imported geometry. Each toolpath is the result of an functioning.
Toolpath Managing director
Operations can be created, modified, and deleted in the toolpath managing director. Information technology is constitute within the managers pane, which defaults to the left of the modeling window.
Hierarchical Organization
The toolpath director displays data in a file tree format, with the Car Group every bit the top-level directory. The machine group contains 
properties (contains the machine definition and stock setup) followed by a 
toolpath group (contains some number of 
operations). The order of the operations is critical, every bit MasterCAM will output each in sequence to the simulator, or when the file is posted for running on the manufacturing plant.
Operation Components
Within the toolpath manager, operations are displayed equally a numbered yellow folder icon with 4 nested components: Parameters, Tool, Geometry, Toolpath.
Operation
This shows the operation number, the blazon of operation, the selected Work Coordinate System (WCS), Tool Aeroplane (Tplane), and a few helpful comments nearly usage.
Parameters
Click here to open the parameters window for the specific operation. The parameters window layout differs depending on whether the performance surface or chain (bend) based.
Tool
Displays currently selected tool for the parent operation. Click here to open up the tool window, where aspects of the currently selected tool may be redefined.
Geometry
Displays quantity of geometry currently assigned for different functions of the parent operation. Click here to open the geometry window, where geometry may exist assigned.
Toolpath
Displays current condition and size of toolpath for parent operation.
Selecting an Performance
Click on the operation folder icon of the desired performance. In one case selected, the operation binder icon volition be open 
and evidence a light-green bank check mark.
Ordering Operations
Selected Operations may rearranged by clicking and holding on the Functioning binder icon, then dragging the Operation to a new position within the ordered Toolpath Group. However, it is frequently more precise to manipulate the operation lodge by using the 
Insertion Pointer and its controls 
. The Insertion Arrow exists equally a placeholder within the Toolpath Grouping to allow for the creation of new Operations. The Insertion Arrow tin can be repositioned by using the 
Up and 
Down controls. Once the Insertion Arrow is in the correct position, you may right click on it to create a new Functioning, or paste an Operation that was previously copied.
Toolpath Visibility
MasterCAM defaults to drawing all toolpaths simultaneously in the modeling window. The toolpath for the selected operation can exist toggled by clicking 
. Ofttimes information technology is most practical to only show the selected operation's toolpath while automatically hiding all unselected operation'south t oolpaths. Toggle this setting by clicking 
.
Toolpath Generation
In virtually cases, MasterCAM will non automatically generate the toolpath for a selected operation after its parameters and geometry have been assigned. If the operation lacks assigned geometry, or has had any changes fabricated to the geometry assignment or parameter definitions, and so the operation is considered "dirty" and the toolpath icon will instead display 
. Dirty operations must be regenerated before verification or posting. Regenerate the selected operation by clicking 
, or regenerate all muddy operations by clicking 
.
Defining Parameters
Parameters | UI Inconsistencies
MasterCAM displays parameters for surface-based operations with a tabbed interface, while concatenation-based and point-based operations use a file-tree interface. Some of the parameters are common across functioning blazon, while others are unique or have multiple names depending on location within the interface.
This disambiguation organizes parameters past the types of operations for which they are applicable.
Parameters | Surface + Chain + Point
Tool Selection
A tool is a piece of cutting hardware that does the actual work of excavating the desired geometry from the stock material. Each tool is a cylindrical piece of metal that has been shaped to perform a particular task. Some tools may be shaped to cut specific materials or give a special finish, while others may be more general purpose. A tool must exist assigned to every performance, and each operation may have just one tool. The fabric-specific template files provided by the GSD FabLab include our default tool libraries. An operation volition pre-populate some parameters from the tool library automatically based on the tool selection. The feed rate, plunge, and spindle speed will all exist drawn from the library, though these can be overridden by inbound a value in the operation parameters.
The effects of many parameters depend direct on the tool selection, so it is important to update all aspects of an performance's parameters (stepover, stepdown, etc) if the tool selection changes. The tool selection interface resides in a dissimilar location of the parameters window, depending on whether the selected operation is surface or concatenation based.
Surface-based operations crave tool selection on the Parameters > Toolpath Parameters (first tab) folio.
Chain-based and point-based operations require tool option on the Parameters > Tool subheading.
Planes
Each operation generates toolpaths co-ordinate to the Work Coordinate Arrangement (WCS), Tool Plane (Tplane), and Structure Plane (Cplane) that is specified in its parameters. The currently specified planes are besides visible in the Toolpath Managing director alongside the operation name. The WCS, Tplane, and Cplane should always match for any given operation.
In most cases, the Elevation aeroplane should exist specified for all operations. The only exception is when machining the underside of a two-sided job (flip milling). In this circumstance, select FLIP equally piece of work coordinate system, tool plane, and construction plane. FLIP plane must first be defined in the Plane Manager.
Surface-based operations allow specifying planes on the Parameters > Toolpath Parameters (first tab) page.
Chain-based and point-based operations allow specifying planes on the Parameters > Planes subheading.
Machining Heights
During an functioning, not every movement of the tool will brand contact with the stock material. In between cutting movements (toolpaths shown in blue), the auto must brand rapid movements (toolpaths shown in yellow) to reposition. In club to forbid accidental impairment to the machined part, MasterCAM requires each operation to specify a safe area where rapid movements will not inadvertently cut through the stock.
Each height value must be specified as Absolute (the input height value is showtime from the WCS origin), Incremental (the input height value is first from the selected functioning's assigned geometry), or Associative (the input height value is offset from the defined stock) . Typically, an functioning volition define a Clearance, Retract, Feed Plane, Top of Stock, and Depth, though some operations may not require every value.
Surface-based operations have machining acme values on the Parameters > Surface Parameters (second tab) page.
Chain-based and bespeak-based operations accept machining height values on the Parameters > Linking Parameters subheading.
Clearance
Specifies the top of the rapid movements at the start and finish of job. Recommended to be stock height + 0.v" accented.
Retract
Specifies the summit that all other non-cutting rapid movements throughout the elapsing of posted operations. Recommended to be stock height + 0.25" absolute.
Feed Airplane
Specifies the top at which the machine begins cutting movements. Recommended to be stock pinnacle + 0.ane" accented.
Top of Stock
Input the thickness of the stock as entered into the properties.
Depth
Specifies the height at which bondage will exist cutting. If the imported geometry has been arranged in infinite at the desired cutting tiptop, the depth should be set to 0.0" incremental.
Parameters | Surface + Chain
Stock to Leave
MasterCAM allows the user to define an beginning, either negative or positive, to be applied between the tool tip and control geometry during an operation. This is useful in a number of situations, but is near commonly used to allow the roughing performance to leave behind a bit of excess cloth for the finishing operations to make clean up afterwards.
Surface-based operations accept stock-to-leave values for Drive and Check surfaces separately. Users can specify on the Parameters > Surface Parameters (second tab) folio.
Chain-based operations accept stock-to-go out values for floors and walls separately. Users can specify on the Parameters > Cut Parameters subheading.
Stepover
Operations that clear a broad expanse typically do so past cartoon a trace across the input geometry that the tool will follow, then offsetting some altitude to depict an adjacent trace, and then on. This offset distance is called the stepover, and has a direct human relationship to the finish quality and machining time of a role. In general, a decrease in stepover corresponds with a subtract in roughness and an increment in machining time. The maximum stepover for an performance should non exceed the bore of the tool. Stepover must necessarily decrease from this maximum as the density of the stock material, and thus stress on the tool, increases.
Surface-based operations that clear material laterally (Parallel, Shallow, Scallop) require a maximum stepover value to exist defined. Users can specify on the Parameters > functioning specific (tertiary tab) page.
Chain-based operations that clear textile laterally (Pocket, Contour 2D/3D multi passes) require a maximum stepover (aka "spacing") value to be defined. The location for inputting this value varies past operation.
Stepdown
When the depth of cutting required to clear stock material from the control geometry is greater than the flute length of the tool, it is necessary to cutting down in layered depth intervals. The height of each depth interval is called the stepdown. In full general, an increment in stepdown corresponds with a decrease in machining time, though, the maximum stepdown for an operation should non exceed the flute length of the tool used. Stepdown must necessarily decrease from this maximum every bit the density of the stock cloth, and thus stress on the tool, increases.
Surface-based operations that clear material vertically (Parallel, Profile) require a maximum stepdown value to be defined. Users can specify on the Parameters > performance specific (third tab) folio.
Chain-based operations that articulate material vertically (Pocket, Contour 2D/3D) require a maximum stepdown value to exist divers. Users can specify on the Parameters > Cut Parameters > Depth Cuts subheading.
Cutting Method
Surface-based operations that clear fabric laterally (Parallel, Shallow, Scallop). Users can specify on the Parameters > functioning specific (third tab) page.
Chain-based operations that articulate material laterally (Pocket). Users can specify on the Parameters > Cut Parameters > Roughing subheading.
This method determines the way in which the toolpaths are drawn across the input geometry.
Machining Bending
Surface-based operations that clear material laterally (Parallel, Shallow). Users tin specify on the Parameters > operation specific (tertiary tab) page.
Chain-based operations that articulate material laterally (Pocket). Users can specify on the Parameters > Cut Parameters > Roughing subheading.
But applies to I Way or Zigzag cutting methods.
Machining angles permit parallel toolpaths to exist rotated relative to the WCS. The default bending of 0 produces toolpath traces with the long direction parallel to the X axis. Increasing the angle rotates the long centrality counterclockwise, such that an angle of 90 produces toolpath traces whose long axis is parallel to the Y axis.
Parameters | Surface Only
Depth Limits
aka "Cut Depths" on Surface Rough Parallel and Surface Finish Profile operations. Users tin specify on the Parameters > functioning specific (3rd tab) page.
Constrains cut moves between minimum and maximum Z heights.
Gyre Tool
Users can specify on the Parameters > operation specific (third tab) > Avant-garde Settings.
Determines whether whatsoever portion of the tool is allowed to cut exterior the perimeter of the bulldoze surfaces. Defaults is to decide automatically.
Tool Containment
Users can specify on the Parameters > Surface Parameters (second tab) folio.
Applicable when containment bend(s) is(are) assigned. Determines how tightly the toolpath is constrained.
Parameters | Concatenation Only
Compensation
MasterCAM applies Cutter Compensation when cartoon toolpaths based on the input chains. Past default, MasterCAM will first to one side or the other from the input bondage by the distance equal to the operation's selected tool's radius. By default, MasterCAM compensates to the 
Left or 
Right depending on what office of the concatenation is clicked.
To ensure that all selected chains offset to a particular side, choose Options in the Wireframe Chaining window, then uncheck "Use cursor position" from the Airtight Bondage field. The Change Side and Reverse functions of the Concatenation Manager provide additional control over bounty direction.
If the input chains are intended to exist centerlines for the operation, Compensation must be turned 
OFF
Users can specify on the Parameters > Cut Parameters subheading.
Lead In / Out
Users can specify on the Parameters > Cut Parameters > Atomic number 82 In / Out subheading.
Commonly used to gradually feed the cutting tool into and out of the stock using line and/or arc elements. This reduces stress on the tool, decreasing overall wear and the chance of breakage.
Multi Passes
Users tin can specify on the Parameters > Cutting Parameters > Multi Passes subheading.
Creates multiple adjacent toolpath traces from a single input chain. The input chain is start a specified number of times beyond a specified altitude at the same Z height.
Break Through
Users can specify on the Parameters > Cut Parameters > Suspension Through subheading.
An boosted negative Z elevation offset to push the tool through the bottom of the stock.
(Avoid use for best practice. Overlaps with stock-to-leave and linking parameters.)
Tabs
Users can specify on the Parameters > Cut Parameters > Tabs subheading.
Prevents a part from being fully separated from its stock material by leaving behind periodic bridges along the base of a contour cut out. Useful for preserving pocket-sized parts when using vacuum hold-down, and necessary for all parts when using mechanical hold-downwards.
Tabs can be generated automatically or manually. When generated manually, users must place the tabs past clicking on portions of the input chain. Tab thickness, width, and ramp angle may also be specified.
Tabs can be moved or deleted individually after creation.
Assigning Geometry
Surface Operations
Most surface-based operations request the consignment of iv types of command geometry: Bulldoze, Bank check, Containment, and Guess Starting Betoken. Of these, merely Bulldoze is required for toolpath generation, however, it is commonly necessary to define additional types of command geometry in order to avoid accidental collisions. Click the geometry component of the selected performance to open the Toolpath/Surface Selection window. In this window, click 
to make your geometry selection or click 
to clear the previous geometry choice. MasterCAM displays selected geometry in yellowish. Printing ENTER to save your selection, or ESC to abolish it.
Chain Operations
Concatenation-based operations use bondage as the primary control geometry, but besides accept a Starting time Betoken for sorting. Some operations (such as Pocket) will only accept airtight bondage, while other operations will accept both closed and open up chains.
Frequently it is necessary to check each chain once selected to ensure the bounty is in the right direction. MasterCAM displays this data via four arrows overlayed onto the selected concatenation. Light-green arrows indicate the entry signal of the concatenation, while red arrows mark the exit betoken. The larger green or reddish arrow indicate the direction of travel that the tool volition follow along the chain. The smaller green or red arrow indicates the management of compensation to exist applied to the selected chain.
Click the geometry component of the selected functioning to open the Concatenation Manager. This window uses its ain Insertion Arrow and controls . Right-click within the white portion of the Chain Director window to bring up the contextual menu. The key functions present on this menu are: Add, Change Side, Sort Options, Delete, Reverse, and Edit Tabs.
Choosing the Add role brings upward the Wireframe Chaining window. At that place are several options in the Selection Method field that can provide actress command over chain selection. By default, the choice method is set to Concatenation, merely Partial, Window, Polygon, and Single methods may be occasionally useful.
Point Operations
Verification
What is Verification?
Verification (aka Simulation) is the process of playing out the generated toolpaths in a virtual surroundings in order to check for errors and omissions. Successful verification (authentic stock and tool definitions, no collisions constitute) is a necessary pre-requisite to performing any existent CNC machining at the GSD. Student submitted jobs volition not exist approved or scheduled until successful verification is demonstrated.
Getting Ready to Verify
During Verification, each selected operation will be processed in the club it is placed inside the toolpath group; unselected operations will not exist processed. Dirty operations cannot be verified, and must be regenerated before verification can embark.
How to Verify
Select all operations that have been configured and will be used. Adjacent, click 
verify selected operations in the Toolpath Director to open the Mastercam Simulator window.
MasterCAM Simulator
The MasterCAM Simulator creates a virtual environs for testing the validity of selected operations. The generated toolpaths are run in order using the current motorcar, tool, and stock definitions. It is vital to use accurate tool and stock definitions (representative of the configuration that is loaded onto the CNC machine) for the verification process to produce meaningful results. In addition to visually confirming that the verified geometry matches the designer'south intent, MasterCAM Simulator also reports collisions that would result from running the selected operations on the CNC machine with current definitions and parameters.
The MasterCAM Simulator window includes the simulation surround, the ribbon menu, and the information pane.
Simulation Playback
MasterCAM Simulator displays simulation progress along a timeline at the bottom of the simulation environs. The timeline is transparent, but becomes opaque on mouse hover. Toggle the simulation playback by pressing R or clicking the play/pause button. Users tin scrub astern and forrard along the timeline by clicking and dragging the reddish slider, or incrementally by pressing B (astern) and South (forward). Users may skip to the previous or side by side operation by pressing P (previous) and N (next). Users may skip to the start or end of the task by pressing Domicile (start) or SPACE (end).
Collision Checking
Collisions occur when any portion of the CNC machine or tool that is non-cutting comes into contact with the stock material. Ensure that collision checking is activated before starting the simulation. First, choose Habitation > Cease Conditions from the MasterCAM Simulator ribbon menu, and and so cheque Standoff. Next, cull Dwelling house > Tool Components from the MasterCAM Simulator ribbon menu, and so cheque all items in the Milling field (Holder, Shank, Shoulder, Flute Length). Finally, choose File > Options and then enable all Collision Checking options for Stock and Mill Tool (Mill tool holder, Mill tool shank, Mill tool shoulder, Mill tool cutting length).
During simulation playback, areas of the stock involved in a collision volition be colored nighttime red. The blazon of standoff tin can be identified in the Standoff Report.
