VBA and AutoCAD 2002 3D kernal

[Anonymous]

With VBA and a 3D model of a pipe is it possible to get the diameter of the pipe and the length?

If not...

Could you draw 2D lines around the pipe's exterior and interior radius using VBA?

Hi,

Yes.

Every AutoCAD object has geometric properties which can be accessed with the
code.

Laurie,



Could you please expand on this please? The only way I've found to get the properties of a 3D object (other than the Centroid and the Volume) was to explode it and look at the properties of the resultant objects. I'd certainly be interested to know if there is a better way.



Thanks

No. 3D entities are abstract objects that describe themselves
in more generic terms. IOW, a cylinder does not understand
that it is a cylinder, so it can't tell you its diameter or
length.

FWIW, the 3d objects created by mechanical desktop can be queried in this
way (radius, faces, surface area, etc.).

Yes they can, but they're nothing like AutoCAD's abstract
3D objects (3DSOLID and BODY).
