https://forums.autodesk.com/t5/inventor-forum/editing-part-in-assembly-part-disappears-from-browser/m-p/5715141#M368877 <P>Some how and from the beginning of Inventor I got used to working top down and find it the best way for new designs and editing parts of assemblies. You can't beat top down design. I know what you mean to all the extra lines but you can control all that in the options/displays of Inventor.....comparing the speeds of designs within the assy betweeen Inventor and Solidworks, Inventor's response keeps up with me while Solidworks crawls when designing in the assembly (I have not tried Solidworks 2014 or 2015 yet).</P><P>&nbsp;</P><P>Still waiting for a power user to help me solve my issue.</P><P>Thanks for the reply</P> Fri, 10 Jul 2015 20:46:13 GMT Anonymous 2015-07-10T20:46:13Z
