BricsCAD can display entities opaque or semi-transparent. This is done with the transparency property to individual entities, to entire layers, and to blocks. A setting in the Hatch command makes hatch patterns and fills separately transparent.
This video shows you how to use the transparency property with entities, layers, and hatches. It clearly explains the difference between the Transparency command and the “CeTransparency” variable. You also learn how to change the fading of locked layers, xrefs, and references being edited.
