It is constantly giving inconsistent&nbsp;relationships error message. And as before if they are "edited" but not edited really, error is no longer present,&nbsp;until new update of geometry of flexible assembly.</P><P>&nbsp;</P><P>I post two new assemblies of flex3 project. they use parts of flex3 so if you place them in this directory they&nbsp;should work.</P><P>&nbsp;</P><P>Cris.</P> Wed, 04 Mar 2015 07:57:47 GMT Anonymous 2015-03-04T07:57:47Z
