Tip: When Hidden Line Removal is Not Correct
Hidden line display may not always work as you expect. Keep the following in mind:
Assembly components that physically intersect may not have correct display on one or both components. If this occurs it is an indication of incorrect component placement.
Curves and cosmetic features that intersect a part in the middle of a surface, i.e., where half the curve is visible and half not, might have incorrect display for the whole line. The display is correct if, in the current view, the curve crosses an edge at the surface boundary.
All the edges in a sheetmetal model are displayed in geometry color when Fast hidden lines removal is enabled (File > Options > Model Display > Fast hidden lines removal).
