I have a problem using smart fasteners: after I select the hole or holes and click 'add', a dialog shows up :
and the holes are deselected immediately and cannot be selected again in the window.
another problem is about toolbox: after I insert a bearing or circlip into an assy. and save the assembly file, upon reopenging the file, the sizes of the bearing and circlip automatically change and cannot to restore to a correct size.
I believe it is some setting error, but I cannot solve it. Please help.
