I have a hybrid issue here.
When I import an Inventor model to Showcase, bolted connections are missing the bolt. I get the washers and nuts but the bolt is gone. I can overcome this by saving the bolt part in a project folder but this is time consuming.
Are there some settings I am missing or is it just another item to add to the fixit list?
Make sure that you selected the correct Project file from Inventor that your IAM was created under. This will allow Showcase to find the directories for all the parts.
Also make sure that you are current on all Showcase SP's. SP4 or even R1 (after SP4).
Since you didn't post your version release I am assuming 2013
