HVAC Ducting Program


The Buzzard

Recommended Posts

Not to take away from Buzzard's program as it is very exquisite, here's another alternative as well for vanilla 2D CAD found here: http://www.cadtutor.net/forum/showthread.php?30545-*FREE*-HVAC-or-Piping-program-for-AutoCAD

 

Thank you for the prompt reply.

 

I think this is a great forum. I should have been here earlier. Now I'll try to be regular. :)

Thank you for creating this program! I am fairly new to CAD but my father downloaded this LISP many years ago. It was not implemented because some key fittings were missing that are often used in HVAC design. I know this was created a while ago but I thought I would mention it.

Reducing elbow

 

 

If it is possible to implement those components into this program, that would be amazing. If anyone finds another program that has already has all of these components, please let me know. :)

Hi,

You need to add the LineTypes CENTER and HIDDEN to your acadiso.lin since they are not available in non-English versions as follows:

*CENTER,Center ____ _ ____ _ ____ _ ____ _ ____ _ ____

A, 31.75, -6.35, 6.35, -6.35

*HIDDEN,Hidden __ __ __ __ __ __ __ __ __ __ __ __ __ __

A, 6.35, -3.175

 

You can find the acadiso.lin as in the following path as an example only:

C:\Users\XXX\AppData\Roaming\Autodesk\AutoCAD 20XX\R20.0\enu\Support\acadiso.lin
