After I release a solidworks part or assembly, there is no bitmap image saved. So when I'm looking through a folder as large icons they are not displayed. When clicking on the part or assembly to see it in the preview window it tells me there is no bitmap preview. When show bitmap in preview window is turned off and I click the file to show the edrawings preview there is text in the preview window stating "The file displayed is out of date. It needs to be rebuit in SolidWorks (more...)" though I have tried this several times and after each rebuild, save, and release it does not fix the problem. Does anyone have any idea what might be going on here or whats wrong?
This particular problem that Neville refers to has been reported as SPR#618533 and is documented in the SolidWorks Knowledge Base in the customer portal. This problem has been fixed for SolidWorks 2012 SP01, but unfortunately cannot be fixed in any earlier service packs (SolidWorks 2011 SP05 or SolidWorks 2012 SP0) because development on those versions is already complete and the versions are in final testing.
That is not to say that there could not be some other issue causing bitmaps to not display as there can be issues with setups on certain machines, etc. (as some other threads in the forum have discussed). However, if the problem relates to references files from an assembly or drawing not having their previews shown, it is likely this issue.
Thanks,
