You may want to investigate your graphics card. I have had this happen to me several times as well, and I am almost certain that the cause is my graphics card. Since it only happens every few months or so, I have just let it go. Solidworks has taught me (the hard way) to save often anyway!
I've always had trouble with Limit Mates.
Whenever I create a subassembly of a cylinder, I make three configurations:

It's a very nice book - I'm sure you can get what you need there.
Thanks for the comments and suggestions, everyone. I’m feeling much better about my HP calculations now…
tygerdawg - I actually came across a PDF of one of those SEW engineering guides about a week ago. It is a GREAT resource to have. Now that I look back, this is the only place I’ve seen that...
Hello everyone. I’ve just joined this site, so let me know if I am posting this in the wrong forum…
I’ve recently begun the sizing and selection of electric drive motors and gear reducers for some chain conveyors that will be carrying steel pipe. It will be fairly standard “engineering class”...
