Flexible Duct In Cad

[Garreth]

Hi all, just trying to find out if there is a way in plan view of showing flexible duct for air con.

Most air con consultants use some cad polyline with a lisp routine that converts it so it looks like a slinky...any thoughts.

Otherwise I will just use a polyline.

 

thanks

I generally use a polyline with a dashed line and choose a very light gray color with a line weight around 100.

Molding polyline (create your shape first) then apply the spiral duct as the "molding"

CAD>LINES>CREATE LINE TYPE> Make a line that says FLEX in it and save it to the library.

Use text at a height you need.

Try this   ()()()()()()()()()()

or this \/\/\/\/\/\/\/\/\/\/\/\/\/\/\

If you are using Autocad try this LISP:   http://www.theswamp.org/index.php?topic=19272.0

Or use a home made linetype

Though I would post my Autocad LIN file if anyone wants to try them.

What’s the cad block you assigned?
