Repair: Optimize Tolerance

Function

Optimize Tolerance adjusts the Tolerances of improperly defined shapes.

Call

Geometry > Repair > Optimize Tolerance

<Optimize Tolerance>

Select Target Shape(s)

Select Target Shapes for which Tolerances need to be adjusted.
 

Check Tolerance Validity

Check to see if the Tolerances of the shapes are proper.  The check result is produced in Output Window.
 

Optimize Tolerance

Adjust the Tolerances of the shapes.

Optimize Only Failed Shape Only

Optimize the Tolerances of only the shapes, which were found to be improper in the Tolerance check.

Notes

All shapes retain internal Tolerances, which the program automatically calculates and assigns.  Sometimes, improper Tolerances can be assigned to very small shapes, which can lead to problems.  Such improper Tolerance information may also come from a Geometry Data File, especially when an IGES file is imported (STEP file format is recommended.)  Improper Tolerances cause improper Boolean Operations and abnormalities in other operations such as Divide Face, Divide Solid, etc.

Computation time for an Optimize Tolerance operation can be excessive depending on the complexity of a model.  It is recommended that the working file be saved prior to executing the command.

The following functions are based on Boolean Operation.

Surface > Fuse, Divide by Curve, Divide by Surface ,Trim by Curve, Trim 2 Surfaces, Imprint
Solid > Divide, Trim, Embed
Boolean > Fuse, Cut, Common
