DetailsHi. I’m working currently a lot with files coming from rhino. Qcad can open them properly any also most operations on them work as usual - except the selection methods.
box select from upper left to lower right works as usual.
on mac os nothing is selectable with single click. thanks for looking into this :)

Hi Martin,
that isn't a bug of QCAD! You are trying to work on a 3D drawing in a 2D Application. QCAD can't handle appropriate the Z information.
Below Menu / Misc / Modify you will find a command which will convert this 3D drawing to a 2D drawing. The command is called "Flatten drawing to 2D"
Note: There is no way to convert this drawing back to a 3D drawing which will work later in a 3D Application.
Hi! thanks for the quick reply!
I agree on that qcad is not for 3D. However not knowing about the z index I just wanted to work in 2D. I don't know what's the best to assume for a user wanting to open a 3D file in qcad (actually most 3D dxf files are only flat drawings in z-layers anyways, so it's basically still 2D editing that's done on them. In my opinion there should be some info that a 3d drawing is opened or the z-information should be just ignored (not sure what that means for the code...).
I actually didn't know that the 3D-dxf was the reason for the "strange behavior" for quite some time until I figured it out (didn't know about the flattening though, thanks for the note!)
so maybe a kind of warning in the console could be useful when opening such file containing 3D data?
