Measure in 3d

[ptplans]

I would like to know the best method to measure an edge of a 3d solid in 3d view.

See attached photo.   Want the measurement for A.

Dimension at A?

DISTANCE, snap to 2 endpoints should work.

DIST is the command name [DISTANCE is a System Variable, which holds the result of the latest DIST command.]

Thank you so much for your reply. It really answered my question. However, for a newbie like me, it was very important to make sure that 3-D snap is turned on, and make sure that the proper snap settings are correct.

In addition to DIST - I will sometimes draw a temporary 3DPolyline from desired points.  Then select that 3DPloyline and check its length property.

This gives me a quick visual check to verify the desired distance.

Thanks for the additional tip!

Been using ACAD for > 25 yrs. - I did not know that. about the DISTANCE variable.

Yes, but I bet you could teach me a lot about AutoCAD. Real nice to work together. Sincerely, Newbie

Another couple of System Variables that are related and that you may not know about:  AREA and PERIMETER, which store those properties from the latest AREA or LIST [when used on something having  such properties] command.  AREA is also a command  name, so the only way to read that one is with (getvar 'area).  With DISTANCE and PERIMETER, you can type them in like commands, and the values are reported in current linear Units settings, or if you use (getvar) the values will be in real numbers.

Just as I thought. LearningPlanet more from You .... thanks.

Thanks Kent,

I don't often need to look at area or perimeter, I'm more of a MASSPROP kind of guy. 🙂 But it's good to know.
