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.)
Construction elements in the 3D Window are displayed using the Surfaces assigned to them via their Building Material. These Surfaces can be overridden at the element level, using the Model panel of the element’s Settings.
If these Surfaces include a Vectorial Hatching, it will be visible in the 3D Window only if you switch the Vectorial 3D Hatching control to “On” in 3D Window Settings, and only if you are using the vectorial 3D Engine.
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.
