Draw a wall that is not rectangular
I'm trying out Sweet Home 3D but I couldn't figure out how to draw a wall that is not rectangular in shape, like this:

At first I thought I could just draw two segments with different thicknesses, but of course then I get this:

In other words, the middles of the walls are aligned, not the insides.

And for something like this the approach with two segments doesn't work at all:

In this case I thought I could draw the wall as a polyline, but when I tried it the magnetism doesn't work and I can't even get the polyline to close.

Re: Draw a wall that is not rectangular
For the first case, you could use walls which are not joined, or if you want to keep them joined, add a third small wall between the two main walls.
For the second case, just use walls with different thicknesses.
See attached example.

Re: Draw a wall that is not rectangular
How did you align them in the first case? By calculating their Y coordinate to be half the thickness difference? Or is there a way to align them in the UI?

Yes

No

Re: Draw a wall that is not rectangular
in the 1st example, i would suggest as two end-adjacent wall, and then modify X or Y co-oredinates so that the 2nd wall aligns of left or right.

especially if you zoom in a lot, you can pretty much drag the second wall into that alignment, and then edit if you need to adjust by say 0.001.

Re: Draw a wall that is not rectangular
As side note, remember that the baseboards are placed only on the sides of the wall, not on the ends. So, if you need to place baseboards where the wall gets thinner it is better to create a "loop". it is a bit hard to explain in words, but very easy to understand looking at the following picture. On the left side you can see how it appears in the "traditional" way, on the right side using the "loop". Once deselected the loop gets hidden, so it resembles to a normal wall.

Re: Draw a wall that is not rectangular

So, if you need to place baseboards where the wall gets thinner it is better to create a "loop".

This "trick" is also very useful to force the end of a stand-alone wall to have a single texture. The end of the wall will display half of each texture used on the sides. No problem if you are using the same texture on both sides but in most cases you want different textures on each side.

To have a single texture on the end of a wall draw a loop (like an extended U) with a wall half as thick as the original. Make sure both legs of the U touch and the resulting double wall is just as thick as the single previous wall. You know have 3 sides you can give a texture, one of which is the end of the wall. (4 sides if you use the same trick at the other end of the wall.)
