3D spiral

Thanks for your help. I may try to get Rhino but does this mean that
AutoCAD cannot handle spirals?

Try this spiral lisp routine:

Hi

Ofcaurse AutoCAD do Spirals, you just need an application or, just one spiral
that you then make into a block , and then insert in different scale, that way
you can make many different spirals from one.
But a Lisp application will do the first spiral you need , and such app can be
found with a search.
Realy, I would try a poverfull search engine and try search for "spiral.lsp" )
P.C.

 

Yes. That is only one of many things it can't handle.

 

No, you can make railings without twisting the profiles.
I wrote a LISP to do that.
In case of interest ask me.

Dear Jochen,

Thanks for your reply.

Yes I am interested. I would like to learn how to extrude any shape
especially a rectangle/square, channel, UB beam etc along a 3D
spiral/coil/helix without twisting. Circles are not a problem now.

I have tried a few other suggestions by others but I did not explaine my
problem
well enough as their suggestions might be OK for simple presentation
drawings.

Looking forward to your reply
Thanks again
