Interface elements

A short description of each element of the Mastercam interface follows:

Menu bar

Contains menus that let you access all Mastercam features and functions. Click or hover over the menu choice to view its commands. Some of the commands have images next to them so you can quickly associate the command with the image.


Toolbars consist of groupings of buttons with related functions.

By default, toolbars are docked below the menu bar. They can be undocked by dragging them outside the toolbar area or by double clicking them. You can also customize your toolbars using the Customize dialog box.

A few samples of Mastercam toolbars are:




MRU (Most Recently Used) –

Note: The MRU toolbar is vertically docked to the right of your graphics window by default. It updates every time you use a new function, so it will most likely not look like this example.

General Selection

For most Mastercam functions, use this ribbon bar to select entities in the graphics window. General Selection is active any time you are not already in a function such as Sketcher, Analyze, or View Manipulation. It is also active during functions which prompt you to select entities, as in toolpath creation functions.

Click here to see a graphic of the default mode of the General Selection ribbon bar.

class=”dropspot” href=”javascript:TextPopup(this)” id=”a8″>AutoCursor

Use the AutoCursor ribbon bar to manually enter X, Y, and Z coordinates or to detect and snap to points as you move the cursor over geometry in the graphics window. AutoCursor becomes active whenever Mastercam prompts you to select a position in the graphics window.

class=”dropspot” href=”javascript:TextPopup(this)” id=”a9″>Ribbon bars

Use Mastercam’s ribbon bars to create and edit geometry. Ribbon bars function somewhat like dialog boxes but look similar to toolbars. You can undock, dock, and move ribbon bars, just as you can with dialog boxes.

Click here to see examples of docked and undocked ribbon bars.

Note that if you do not have a function active that uses a ribbon bar that the href=”javascript:void(0);” id=”a1″ onmouseover=”= 4 && typeof(BSPSPopupOnMouseOver) == ‘function’) BSPSPopupOnMouseOver(event);” onclick=”BSSCPopup(‘../Ribbon_Bars/Blank_Ribbon_Bar_example.htm’);return false;”>blank ribbon bar is displayed by default.

Operations Manager

Lists all operations for the current file. Click the tabs at the top to toggle between Toolpath Manager and Solids Manager.

For additional information, see Operations Manager.

Toolpath Manager

Lists the toolpath groups and machine types for the current file. Use the Toolpath Manager to generate, sort, edit, regenerate, verify, backplot, and post any operation. It includes both associative and non-associative toolpaths.

For additional information, see Toolpath Manager Overview.

Solids Manager

Lists each solid in the current file along with its operation history and associated toolpaths. Use the Solids Manager to edit solids and their operations.

For additional information, see Solids Manager.

Art Manager

The Art Manager tab is a central location where you manage the elements of the current Art model. If you have installed Art, the Art Manager tab is located in the Operations Manager, along with the Toolpath Manager and the Solids Manager tabs.

For additional information, see Art Manager Overview.


Use viewsheets to create different part views, each on its own Viewsheet tab. With a viewsheet you can define a specific view orientation and scale, store modified level settings, and use a bookmark to define a restorable viewsheet state.

Please see Using Viewsheets for more information.

Graphics window

The graphics window is the workspace in which you can view, create, and modify your parts. The graphics window also displays information about the current measurement system (inches or millimeters), the views in which you are working (Gview, Cplane, Tplane, WCS), and the coordinate axes for the current views.

Status bar

The Status bar is located along the bottom of the Mastercam window. It provides quick access to functions that let you modify attributes, levels, groups, and orientation (views and planes) of geometry and toolpaths in the graphics window.

Side bars

Vertical display areas on the left and right sides of your screen.

The side bars display the MRU (Most Recently Used) functions toolbar on the right side and the toolbars identified in the Mastercam configuration toolbar state (Settings, Toolbar states) on the left side.

MRU (Most Recently Used) toolbar

Use the MRU (Most Recently Used) toolbar to quickly access Mastercam functions that you use most often. The MRU toolbar is vertically docked to the right of your graphics window by default. The example shown below is an illustration of the MRU after it has been horizontally docked.
