Alternative for my current method of retrieving beam (solid entity) lengths.

[gizmowiebe]

Hi There,

for years I have been using an VB program to retrieve beam (simple quare block with scaled Z value) lengths from modelspace. In modelspace a construction is shown made out of three different blocks. 90x90xL, 90x45xL and 45x45xL. where L is a scale Z dimension. The method I use I describe also in the tutorial below:

http://www.visiblevisual.com/jupgrade/index.php/autocad-vb-vba/26-draw-beams-and-get-parts-list-with...

This method works good but has a big few setbacks. 

1. I cannot use flatshot or create other 3d views showing the beams. They are simply left out

2. To change the length I cannot use 3DSTRETCH (or pull an arrow) but I need to go into properties and change the Z scale.

What I'd like to accomplish?

a. Could I replace my blocks by a BOX entity (or extrusion) to create beams. (I know AutoCad doesn't allow to retrieve Solid Extrusion geometric values. So I guess this is no option.

b. Would it be possible to create a dynamic block from a 3d extrusion with a LENGTH value. (If this is possible than I need some input in how to do so. I've looked but didnt founds a solution like this')

c. Any alternatives I havent thought of. ....

Help is appreciated. I hope one of you can provide me with a clever solution. 

Thanks in advance,

Wiebe

I attached a VBA sample routine (post # 10) that does a pretty good job for generic rectangular solids.
