Crashes in print window setup and 2D icon

Unfortunately I have problems with two files… This happens from two days ago, after a big .step import!
I don’t know if it has corrupted something… But two files don’t work in the right way…
In this one, when i go to print window, click view and then vectorial, it crash.

Nuovo progetto.3dm (635.7 KB)
The second, unfortunately, is to much bigger to upload… meh.
Anyway, it crash after opened the file, once select on a casual polysurface and click 2D drawing icon.
Thank you very much and forgive my english…

I do not have any problem with your model. However, your model references a file “download.png” that you did not include, and I suspect that the problem is related to that particular file.
