Hello all,

This is my first post on this site...hopefully not a dumb question. How do I take measurements at different plane sections through an assembly? I am able to view sections but not able to pick off measurements at the sections. I was thinking to intersect the partbody with a plane and then pick off measurements from the intersection as a work around?

Thanks in advance

I just checked and you can take measures while sectioning in both the assembly window and the section window. (at least with R18)

Make sure you have the Tools + Option activated to ALLOW MEASURES ON A SECTION WITH A SIMPLE PLANE

Tools + option? I'm not sure what you are referring to. Where in the menu/toolbars do I find this?

On the top menu of the CATIA screen, click the TOOLS menu, and then click the OPTIONS sub-menu. This will bring up the OPTIONS window where you can define how you want CATIA to behave.

In the OPTIONS window; on the left side is a "tree" of sections (kinda like a list of workbenches). Click the MECHANICAL DESIGN section on the left, and then click the ASSEMBLY DESIGN sub-section.

Across the top of the OPTIONS window are a series of tabs / pages. Click the DMU SECTIONING tab to see the list of options.

The top portion of this page has about 8 options for the SECTION PLANE. Activate the last option to ALLOW MEASURES ON A SECTION CREATED WITH A SIMPLE PLANE. (the box in front of the option will be orange when it is active)

Click OK at the bottom when finished setting the Options for your CATIA session.

These options are saved with your userid, and will stay in effect until you change them. So, you don't have to set them everytime you start CATIA.
