If I remember well it is possible to save the 3D section output but I don't remember exactly how.
You could combine this output from 3D section with the product that you don't want to section and you will get the result.
It might be that although you don't have the license, you could achieve with macros the missing functionality from LWolf example. You could check for it.
I'm sorry, I am not good at English, so I may be misunderstanding.
· After executing the macro, click the curve that becomes the guide curve (spine).
· Enter section number in Input Box.
· Create a new CATProduct and create CATPart (sketch) for the cross section in it.
(This is unsaved)
Also, in order to execute this macro, this library is necessary. Link
Please put it in the same VBProject under the name "KCL.bas".
