Analysis menu </LI></UL><UL><LI>If using a shrinkwrap, best results are obtained by creating a shrinkwrapped solid; also make sure to include any necessary datum features </LI></UL><UL><LI>To improve analysis time and resolution of the analysis feature, the surface of the “GROUND.PRT” can be divided into any desired number of separate surfaces (i.e. quadrants) </LI></UL><UL><LI>64-bit machines are recommended for larger/more complex assemblies </LI></UL><UL><LI>More information can be found by searching for “user defined analysis” in the Pro/E Help menu as well as the Behavioral Modeling
