Dimensioning in 3-d

[bhagood]

Can someone help me figure out how to dimension in a perspective view of a 3-d object. For instance, If I were to create a cube, and set it into a viewport at at 3/4 view, whenever I try to pull dimensions from corner to corner, all I get is the distance as it appears, not the ACTUAL distance between the points. Is it possible to have dimensions in such a view? Any help is appreciated!

I think bhagood is encountering the problem with using VW dimensioning, which are 2D objects, in a 3D environment. This has been discussed on another thread, I will try to find it.

There's a work-around at Vector Depot (Misc Page) in PDF format.

Scroll down the page to:

It's not a tool, rather a way of using layer linking to give the look of 3D dims.

At Vector Depot there is a set of script to help generate and dimension exploded isometric view. It has an isometric dimensioning tool that uses islandmon algorithm.

It works only on isometric views (snapping on 3D edges along XY or Z planes). It's a workaround waiting for a native 3D dimensioning from NNA.
