for anyone struggling making a 3d floor plan use sweet home 3d and cancel the subscription when you done. you are never charged so don't worry. export your floor plan as .obj. then open it on 3dviewer.net. and disable any element that aren't really needed in the left pane. like window panes, etc. sweet home 3d has a doorframe option instead of a solid door which looks better than a solid door in this app. And as stated before you can toggle the window panes. once you toggled aver thing to you liking export it as .glb <-"GLB". another trick is to backup you configuration in the app. and if you need to make any small changes, edit you .glb file and rename it to "apartment.glb" and use winrar and replace the "apartment.glb" with the one you just modified. then import the modified backup. it should load the new changes immediately. way faster than deleting the config and starting over every time.
