Does anyone know how I cross hatch an area on a drawing? I want to show an area for texturing on my part, and I can't for the life of me figure out how to use entities from my part (i.e. edges) to cross hatch an area on my drawing. I see the hatch / fill command, but it seems I can only use this on entities I created in 2D, not items from a part.
It depends on what You really want and/or how You want to define it.
In most of these cases, the most flexible way is to use a cosmetic in the part itself which can easily use existing geometry and will be independent of drawing views etc.
When creating something in the drawing only, You have to sketch the whole closed (!) shape, referring to the existing geometry, which can be model dependent (even updating automatically), but is not as reliable as a cosmetic.
