Strange…, it crashes rhino on both machines. One Dell precision T7400 (old but still tough) and on my new laptop dell precision 7520.

Steps:
Select the rail
Select Sweep 1 Rail

No crash here either, same version as Charles… Can you run SystemInfo in Rhino on the machine(s) in question and post here?

Ah, wait, I just got it to crash following your sequence… :frowning:

What’s happening here is a bit unpredictable, if I select the rail, then run Sweep1, I can usually get all the way to the dialog and even accept that, but the sweep is not created and Rhino crashes. Sometimes I have to run it again to make it crash… Bug report submitted: https://mcneel.myjetbrains.com/youtrack/issue/RH-44903
