When I say filling I should have be more clear - shading is what I'm after. Drawzilla - I usually do just what you recommended but I need them shaded. The only option on the callout is to shade the arrow which I'm not using. The engineer has specified different shear walls with 4 different symbols - solid triangle, solid triangle with larger triangle around it, circle with solid triangle inside and just a triangle.
The engineer sent me a PDF legend but I still have to insert them into the shear wall plan at the right locations. I'm thinking would be best to modify a square to be a triangle and then make it solid shading.
Hey if it comes down to it I will draw them by hand after printing the plans. Quite frankly the building dept could care less - only that they can figure out what's been built.
