CAD File Association
Question
When I try and open from my file I get a message box saying ‘windows can’t open a cad file’ and gives me option to open with another program on my PC, or search the net for a suitable program.
Answer
If you want to open a CAD file, the file association can be done manually, even though we recommend to open Landworks first and then open the CAD file through File > Open.
Anyway if you want to set that file association, all you have to do is click on ‘Browse…‘

And then, select the cad.exe file from:
- RealCAD users: C:\Program Files\RealCAD-v8
- LANDWorksCAD users: C:\Program Files\LANDWorksCAD-v8
- ArborCAD users: C:\Program Files\ArborCAD-v8
Once you click OK, all your CAD files will be associated with the respective program you choosed.
