Actually, the model itself had some problem but Fusion didn’t detect it until the model was inserted.</P> <P>&nbsp;</P> <P>We can just click the Compute All button under the Modify panel on the ribbon to see the same error. The Insert operation is just rebuilding the model based on the history then the issue is exposed.</P> <P>&nbsp;</P> <P>I’m looking into the model and try to figure out the root cause. Meanwhile, I have repaired the model and send back to you via email. I will follow up with the development team for that. What I did is, click Compute All, then edit each feature to make sure they get upated. You can either import my model as a new version or repair it on your side.&nbsp;</P> <P>&nbsp;</P> <P>BTW, Compute All should be a good way to make sure there is no problem in the model history. Hope it helps.</P> <P>&nbsp;</P> <P>Best Regards,</P> Fri, 05 Jun 2015 11:21:39 GMT NicolasXu 2015-06-05T11:21:39Z
