Truss Program

I was wondering if it is feasible to write a VBA routine to draw a truss
profile? Also if it is, I'm new to writing VBA(Very New), how would I go
about it?
In Lisp I have to define the different points of span, define the rise and
run of the slope, access the command to draw the plines between the defined
points, etc.

 

Yes, there is no problem doing it. How to do it, though, is dependent
upon your situation, end goal, etc.

If you did it in lisp then you can use the same approach. VBA allows you
to add more GUIs and makes the coding process easier if you create
programming objects [not talking about anything drawn in CAD] instead of
using straight variables.

OK, now that I know it can be done, the question is how. I did do it in
lisp, but want to add more to it, like dialog boxes and the like. The only
problem is how! I know not where to start, for I no nothing. I've looked
at other code and I don't understand the syntax of VBA. I've tried looking
online for a good free tutorial on how to understand the syntax, unless you
can give some pointers.

Well, you'll get lot of opinions here on how to go about learning it. If
you search the ng, there are a lot of threads on that topic. I,
personally, recommend going to your local library and getting either The
Complete Idiots Guide to VBA or VBA for Dummies. Both are good primers
that teach you vba from within MS Office. Once you learn the language,
picking up AutoCAD specifics shouldn't be a problem and you can always
get Joe Sutphin's book - its a great reference but not the best primer.

Mike knows his stuff. His advice would be good stuff.

The only thing I could add is that you may want to consider not using custom objects, but draw 3D solids if you are planning on working in 3D.

This way you have collaboration with other trades easily.

Good luck!

you can play around and learn vba also a few bad habits, i would recommend
uising the following book
its cheep and very good.
AutoCAD 2000 VBA Programmer's Reference
by joe sutphin
Even though it is for acad 2000 most of it is still relevent to 2002, 2004
you can also download it as an e-book from www.amazon.com

 

Hi Anthony.

I talk to you a while ago (about VBA books...). Why dont you send me the
input you expect to do and the output you expect from your macro? I will se
if I can start you up ...

Hi,
If you new to VBA, you should begin with simple applications, like
routines with layers, text, blocks.When you became more familiar with
the code you may try to write someting more complicated.
