Geometry

The ‘Geometry’ section of the Advanced tab enables you to:

Decide the action taken by CAM Assist if it encounters an error due to a faulty model.
Indicate if CAM Assist is to compute a toolpath strategy for the full part or only for those faces selected by you.

Features

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

Option

Description

Action on model with errors

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.

For the majority of error instances, CAM Assist will 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’.
