got an idea id like to show but?

Hi my name is Doni and this is my first post here. btw John very cool site. But I have an idea for a circular facility but I use a cad program and from what I have seen this site doesn't support dxf files. I'm wondering how I could I post my idea here so i could read some feedback on it. Any help would be greatly appreciated.

Most od us use cad programs that read dxf files, so just attach it, or create a JPG from the screen image. Andre

thank you andre but dxf are not allowed to be attached and i dont have screenshot to turn what i see on my screen into a jpg

here lets see if i can upload it usiung a zip file

There's several freeware and shareware screen cap programs online. Check out download.com or a similar software search site.

It's fraught with all kinds of problems. cheers john

besides no windows or doors to any rooms or such but what problems do you see john?
