Geometry

The ‘Geometry’ section enables you to redefine the geometry to include aspects of the original model that you wish to include or omit from CAM Assist’s machining strategy.

For examples and guidance on each of the Geometry features, see Using the ‘Geometry’ section.

Features

The following table describes each option in the ‘Geometry’ section, as shown in the above screenshot.

Description

Action on model with errors

These are the list of actions that CAM Assist could take when it cannot correctly parse the model.

Errors can occur due to a fault in the model, or due to an incompatibility between the underlying CAD systems used by Mastercam and CAM Assist.

In most cases, CAM Assist can continue to compute toolpaths for most or all of the part.

Available options:

Fail on errors - returns a description of the model problem.
Proceed with errors (default) - process the model as received. The generated program may miss geometry or be incorrect in areas where the model has errors.
Attempt to fix errors - CAM Assist will try to fix the model's geometry. This can fix errors, but can result in modifications to the geometry that mean the program misses geometry or is incorrect.

The better option between ‘Proceed with errors’ and ‘Attempt to fix errors’ depends on the specific part and error. In many cases, the best approach is to first try ‘Proceed with errors’ and, if that output is not correct, try ‘Attempt to fix errors’.
