It would be great if it was possible to apply a hatch / filled region to a face of a model. It would also be great if the hatch would then come through into drawing files as hatched regions.
I use a lot of isometric views on my drawings to show complex profiles / geometry, and I use hatch to show the different types of finish. Unfortunately, using color to do this is not an option for me, mostly due to this not working out well for customers. Adding hatch to complex geometry in the drawing file is a pain, and often involves me sketching over projected lines that are already there for the drawing to recognize hatch boundaries. Having the capability to add hatch to faces in the model (and even partial faces) and having the hatch pull through to the drawings would be a big time saver, and would get rid of a lot of headaches!
