Display of Vectorial Fill
Vectorial Fills use a hatching pattern, and can be used to represent the cut surfaces or top covers (cover fills) of construction elements. You can also assign Vectorial Fills to Surfaces, which are displayed in the 3D window.
Elements will display the hatching of a vectorial fill on the Floor Plan only if you have activated View > On-Screen View Options > Vectorial Hatching. (Otherwise, the on-screen display will show the fill’s bitmap face.)
Section/Elevation/IE and 3D Document windows will display vectorial hatching only if you have checked the Vectorial 3D hatching box in the Model Display panel of the Settings dialog box.
