projection of room walls on a 2D plan
Hello,
I'm a newbie to Sweet Home 3D and a new Java developer. I work on house plan with Sweet Home 3D which is a very nice application.
I need to generate 2D plan of the wall from the 3D model. I read at the SH3D API which is very well documented and try for one week to generate a SVG file containing the projection of the wall.
Today, the result is not as good as expected. I encounter the following issues: - Unable to locate the door and windows on the wall and draw them at the right place.
- Unable to detect precisely which room is behind a given wall. What is the way to do that?
- Look's like sometimes the room boundary points are in clockwise order, and sometime in anticlockwise. So I suspect that some of my rooms are drawn in reverse order...
- Difficult to remove the very little walls generating when a door is encountered in a wall. Like in the following draw:

Deverne,
I can't follow what you're trying to explain, and it's not because of my English... If you share your SH3D file, maybe that would explain some things. You can also share a Java file, maybe someone else understands that (but not me).
1 - The command Plan --> Export to SVG format produces an SVG file with a high quality 2D plan, but I guess that's not what you want? Do you need a cross-section? Can you give an example of what you need? Some image from Google Images maybe? 2 - I tried drawing a few rooms in all kinds of orders: clockwise, counterclockwise, random direction walls. When I inspect the inserted rooms with the AdvancedEdit plug-in, all room points are given in clockwise order, so that doesn't confirm your suspicion, although the plug-in may sort room points in that order.

Re: projection of room walls on a 2D plan
Deverne, I'm not sure to fully understand what kind of projection you're trying to build, and for which purpose. A drawing is sometimes much more helpful than any word. If you're trying to create a parallel projection, using Java 3D parallel projection should help you to get a result much faster (but you won't get an SVG output). You can upload your code anywhere and add a link to it here.
