Hidden Line
Toggles between normal wireframe display and a display that simulates a hidden line drawing. Hidden line drawings hide portions of the model, such as edges that are obscured from view by other parts of the object closer to the camera.
It also draws contour lines around the silhouette of the object. This provides a view of the object, which reduces visual complexity. For example, it lets you see the shape without the distraction of internal edges and lines that regular wireframe displays.
Silhouettes of surfaces include the effect of any bump or displacement maps. Note that the silhouette is not calculated when moving the view, such as when tumbling.
All Windows
If this option is checked, the geometry is shaded in all modeling windows.
If it is unchecked, the geometry is shaded in the current modeling window only.
Optimize during Tumble
Disable Silhouettes
When this option is checked (default), the outline of the model is not drawn during tumble, to speed up the operation.
Tessellation
Use existing tessellation
If this option is unchecked, the model is re-tessellated using the options below. It is checked by default.
Tessellator
Fast – Tessellates more quickly and less accurately.
Accurate – Tessellates more accurately and more slowly.
Tolerance
This value controls how accurately surfaces are tessellated.
Limit edge length
This option only appears if Tessellator is set to Accurate.
If checked, a Max edge length slider appears, to control how large the triangles can get. If unchecked, there is no limit on the size of the triangles.
Max edge length
Specifies the maximum length of any triangle edge (in current linear units).
