Can someone share a screenshot of how an external door should be drawn in AutoCAD so that it gets picked up by the AutoDefine function in Hevacomp, please? Windows work great but however I draw doors they never get recognised and need be added manually. (I use the appropriate layers). Thank you for your help.
All you should need to do is to assign the correct layers as below. If the doors are not being picked up then I suspect that perhaps the outline of the room may be overlapping the plan of the door. If you delete the part over the door it should work fine.
However personally I would suggest that simply entering the door surface in Hevacomp would be far quicker than altering your DXF drawings and re-importing it etc. In practice Autodefine nearly always requires a certain amount of manual tracing as well to complete a model.

Thank you for your reply. I have drawn the doors like this. No overlap. However, still no luck. What should be the geometry of the door? Is a simple rectangle enough? Is the quarter circle needed as well? (tried both ways by the way). Any help is appreciated.
In general I would simplify geometry as much as possible. The code solely looks for the layers so will not require door swings or anything like that. The exact same principles as for windows apply. Out of interest are there many doors in the project?
If you wanted I could take a look at the project and DXF?
