Part Features Not Displayed Correctly

Problem

A part has features that are displayed incorrectly or are not visible at all.

Solution

In most cases, the part will display correctly if you change the drawing accuracy:
Part Properties → Drawing Accuracy → enter a numerical value, e.g., 0.1.
This sets the maximum deviation between the mathematically defined surface and the displayed surface to 0.1 mm. This usually fixes the part’s display.
Note: If you set a very small value, the number of surface triangles increases, which may slow down part handling.

The part may also contain geometric errors that can be fixed with the Heal function (in the part model, right-click → ACIS Geometry → Heal).
