Dear Michael,

A short time ago I bought the 2nd Version of MoI and thank you for this awesome software.
Working with MoI I had a problem with the Helix . After creating it, if I use the tool “Rotate” from the “Top” view, MoI freezes up for a few seconds and then it unfreezes and so on.
I add my file to this post.
I use a 64 bit Windows 7.

Thanks,

Marco.

Hi Marco, it's the projected intersection snap that runs into that problem.

A helix projected down flat ends up being a highly self-overlapping curve, which takes much longer for the intersection calculation than it normally does in other cases.

So it can help to turn off projected intersection snap when you are dealing with something like that, to do that go to Options > Snaps > Object snap options, and uncheck "Use apparent intersections".

Once that setting is off, that freezing should stop.

In the future I'm going to try to detect when a projected curve would overlap around on top of itself a lot like this and try to skip just those curves from the projected intersection calculation.

Please let me know if you still have any problems after turning off that option.

Hi Michael,

thanks for your reply. After turning off that option, everything works.

Marco.
