How do I draw 3d pipes/ducting in autocad 2002

How do I draw 3d pipes/ducting in autocad 2002

(OP)
I am struggling to draw 3d pipes in autocad 2002. Has anyone got advice on how to actually do this?

RE: How do I draw 3d pipes/ducting in autocad 2002

Honestly I would probably avoid it in plain AutoCAD since you have limited editing ability after the pipes are modeled. I would stick with isometrics which you can accomplish by setting your snap from rectangular to iso. But since you asked...

I think using sweeps would work best. Basically you draw a polyline to represent the path, fillet your corners to have the correct radius for the size pipe you are using. After that you basically draw a profile (circle in this case) to sweep along the path. Look up "sweep" in help if you need a little help with the command.

Thank you for your time.

It's been a while since I did this, but I believe in AutoCAD it is refered to as "extruding along a path." It's not too difficult, but it does take some getting used to. You may also have to look into the SUBTRACT method for removing material.

You would be better off purchasing a third party program to work inside Autocad.  There are several programs avaialble.  Mech-Q from Asvic Software seems to work well at a reasonable price.

RE: How do I draw 3d pipes/ducting in autocad 2002

Mech-Q is fine for what you need. But if you are OK with AutoCAD, you have all explained in Help. Also, look for some LISP files (3Dpipe) on Internet.
Good luck.
