KOP won't constrain in inventor

Which parts are you talking about? We haven't had problems with any metal parts but some of the electronics parts are molded so that their sides are not orthogonal. You can't use multiple flush constraints - you can usually only use the bottom. Make holes and constrain them that way. While it may seem like a bit more work now, at least you won't forget to put in all the parts later.

We use a lot of 8020 and there is only a tiny flat that is suitable for flush constraints. Also, Inventor 2009 seems to take much longer than 2008 did to calculate constraints. It helps to pick the least complicated part first to minimize the calculation time.
