I have some questions about your generate-3d-idf-data.ulp.
According to your document $EAGLEDIR/doc/ulp/generate-3d-idf-data_en.pdf the height of a package is drawn in layers 57 and 58. The board in layer 50.
How do I create these layers?
I patched the ulp by changing layers to 150, 157 and 158. This way I'm able to create the layers and draw the contour of the height of the part.
Why isn't it possible to create layers 50, 57 and 58?
Thanks for answering,
