PreForm taking REDICULOUSLY long time to calculate supports


Anyone else having this problem? PreForm taking RIDICULOUSLY long time to calculate supports. It has got worse and worse over the last few updates, and now, it has taken nearly 2 hours to calculate for 5 fairly simple parts. It seems mostly Checking my models for printability. Well, hey, I KNOW they are not printable, I haven’t added the supports yet fer goodness’ sakes !! How do I turn that off, I only need to know if there is a problem when I am ready to print. Please folks, sort this out, I cannot spend 3 hours supporting a few pieces, they would have built by now and the parts would be in the post by this evening. This is just wasting huge amounts of my time, for no good reason at all!

Excuse rant. I need a switch to disable this, please…
