I've had this happen several times now; I create a beltfeature, and SW complains saying that the pulley's are fixed. But,I have unchecked the check box to have the belt size drive thepulley position. I.e. the pulley's are all fixed and I want thebelt to adjust to fit the pulleys.

I called my dealer, and was preparing to show him the error, so Iright-clicked the belt feature and choose to edit it. Then, Iescaped out of it, without any changes. The error disappeared. Notethat I have made several such attempts before, trying to force SWto re-evaluate the belt. I also tried checking the box to have itrebuild that way, and then re-editing the feature and uncheckingthe box. I also tried the standard Cntl-Q.

When this problem first appeared, and I couldn't resolve it, Idecided to just recreate the belt, but that didn't stop theproblem. It looks like most of the time, SW was ignoring that thischeck box was unchecked.

Anyone else having problems with belts?SolidworksAssemblies
