https://forums.autodesk.com/t5/inventor-forum/corrupt-model-changing-frame-generator-sketches-rotating-beam/m-p/5614355#M377475 <P>I posted an issue about this model yesterday. &nbsp;I thought the problem was related to welds. &nbsp;I removed all but 4 welds, and removed all beam end treatments. &nbsp;Corrected some errors that were showing up in sketches. &nbsp; I finally got the model back up and running with no errors. &nbsp;</P><P>Now once again the frame generator sketches are changing for some unknown reason causing problems. &nbsp;and the last beam that was placed keeps rotating. &nbsp;I check in frame generator and it states the angle is 0 deg. &nbsp; ???????????????????????? &nbsp;HELP &nbsp;whatcold be causing these sketch changes?</P> Thu, 30 Apr 2015 15:50:23 GMT Anonymous 2015-04-30T15:50:23Z
