Thank you for answering.
I understand how busy you are now working on priorities for moi3d, as a true fan of your program, I wish you strength and patience!

And how difficult is it to create the possibility to develop such a bridge from your side?

I mean, is it possible to access the geometry inside the scene in moi3d, so that a third-party enthusiast could create such a bridge by himself?

I will say that I made a shortcut for a bridge in plasticity in moi3d.
script: /*?Export '%temp%/1.stp' */ moi.GeometryDatabase.fileExport(moi.Filesystem.getTempDir() + '1.stp');

But it's just a shortcut, I would like to have the transformations happen on the fly without my direct involvement.
