Hi! I've tried to import dxf but it not work properly. Loads only simple rectangular external shape. When try use complicate shape or  add "MATERIAL" layer - "EXTERNAL BOUNDARY does not exist" error message appears.
Then I've tried directly write hjs script, it's loads only with external shape. With materials coordinates HYRCAN crash.
What it could be?
