how do i add various rooms on an imported CAD file, because at the moment i can only work with one room if i try to add another polygon it cancels out the room i have worked on before
Dear Bernard Ruziye
First you have to decide whether you want to build the whole floor or just one room.
Choose an "interior scene" or the "floor" according to your needs, see the options in the picture below.
After you have chosen your scene, you can still add new rooms later or create a floor under the main menu "Insert" and "Scenes".
Do not hesitate to contact me again for further questions.
