If a material's Geometry Map links to a Cell that uses a Shape(s) element type, AECOsim Building Designer SELECTseries6 will not display the resulting Geometry Map pattern when generating a Drawing View. I don't recall seeing this behavior in previous versions of AECOsim Building Designer.
This issue has been logged as Defect# 323876. A few interim solutions include:
1 Cache the Drawing - this should properly display the Geometry Map even when Dynamic mode does not.2 Drop the Shape element used by the Geometry Map to invidual linear elements. 3 Drop the Shape element used by the Geometry Map to invidual linear elements and then reconstruct them into a Complex Shape.
