When Use Global Settings for Solids is checked in the Document Control dialog, use these radio buttons to toggle between a Rough or Finish tolerance on the part. The rough or finish tolerances are set in the Document Control dialog.

Advanced Settings


Use the Advanced Settings to override the tolerances set in the Document Control dialog on a process-by-process basis. Click the Advanced Settings button to access the Advanced Settings dialog and then select the Override Global Settings checkbox to apply the clearance and tolerance values to the process. A blue checkmark will appear on the Advanced Settings button if the global settings are being overridden.


This section allows the user to set the interaction between toolpath and fixtures that are to be avoided. A fixture may be defined as a sheet or a solid designated as a fixture. There is a text box for the clearance value from a Fixture. This value is the additional distance the toolpath will be offset from the object.


These are the machining tolerances for the toolpath, or the margin of error. The toolpath may deviate by up to these amounts. A looser tolerance will require less memory and creates shorter output. To provide as much flexibility as possible, there are separate settings for Cutting, Stock, and Fixture. The Cutting tolerance is the tolerance of the toolpath over the selected face or faces—the area to be cut. The Stock tolerance is the accuracy of the toolpath’s interaction with the stock definition. The Fixture tolerance specifies the accuracy of the toolpath’s interaction with areas that are to be avoided. The default value for all selections is 0.005″ or 0.127mm.
