Hope you can find it's a good place to talk with others for Fusion related questions/issues.</P> <P>&nbsp;</P> <P>Regarding the problem you mentioned, yes, such problem is one of the major areas we're actively working on. We have improved a lot of such cases in recent updates and there could be still some ones we were not aware. Would it be possible to share the model where you encounter the problem so we can look into it and figure out the solution?</P> <P>&nbsp;</P> <P>You can either Export the entire file as .F3d format or Share Public Link with me by enabling the download permission.
