Dimensional Analysis taking forever because you are struggling to click on points?

Ever feel like your geometry is filled with bottomless holes?

Can’t click the bottom of that hole for a hole and pin?  

Complex geometry making it difficult to connect points and set up moves? 





There are multiple methods of selecting geometry in CATIA other than a mouse click. If a point is covered or blocked by geometry, the following  will show you how to find the point and select it.

In this Tips and Tactics, we will be covering the CATIA Selection Toolbar.

Those familiar with 3DCS Variation Analyst Multi-CAD may get frustrated when switching to 3DCS Variation Analyst CAA V5 Based integrated in CATIA V5 as they attempt to select a point meshed with other points and buried inside a part under other surfaces. This is a quick method of selecting such a point quickly and easily.
