Hatching 3/4" scale (or larger) details drawn at real scale (1" = 1") takes to many system resources and is extremely slow. In other words hatching a 1/2" X 8' drywall with the "sand" hatch it just wont fill the area. I have had similar issues while hatch solids on windows (1/4" scale).
Tech support asked me to scale up detail by 3 or 4 times befores hatching, then scale back down.
AutoCAD does not have this issue.
I use solely plan sets to scale up to 3/4 on published sheets.
I have tried paint breaks to reduce hatched area.
Does anyone have a better work around than scaling up and down.
