We are attempting to export Revit drawings to Cad but we have run into some issues with some of the hatching showing up. I highlighted the Cad hatches with green but as you can see there is a large area that should have that same concrete hatch but doesn't. Here is the Revit screenshot.
Also here is my Revit export settings.
I don't think that it is a mapping issue either because one of the three concrete walls shows up just fine, I just think that when it exports that it isn't properly identifying what needs to be hatched.
We try not to use 3rd part software we aren't familiar with. I did find a solution to some of the problem; I set the wall and ceiling hatches I need from the automatically generated ones to specific ones in the acad.pat file. For ones that are not found there, such as fire rated walls, I did have to make custom hatches (attached) for them and added them to the .pat file so I could select them in the Revit export.
Only issues I have had:
1-If a wall is viewed not running North/South (up/down), the custom hatch is not rotated and will need to be for each of said walls.
2-Even though the hatches say they export at 1:1 scale, I have to re-enter 1 in the scale field for them to show properly.
