Changing a fill pattern from drafting to model when in section and detail view.

[Anonymous]

I am creating wall sections and I want to change the fill pattern from drafting to model so I can minipulate the pattern. I selected a multitude of elements to change from rigid insulation to CMU and all were the same in the fact none could be changed into model pattern.  Heres what I did; I slected an element, then went to the Paint Tool selected Surface Patterns, then Pattern, then Fill Patterns but it wont let me choose model.  Is this possible?

Model patterns cannot be used as cut patterns. You could use Annotate > Regions > Filled region, and create as many types of filled regions as necessary, to use them as hatch patterns for the different parts of your wall sections. These filled regions do allow the use of model patterns.
