Hi, this is a wonderful software but I have same problem with wall lengths.Shadow,
Your observation is correct: walls are drawn from "centre to centre". If you need EXACT interior dimensions you have to take this into account.
Workarounds:
1 - You could make your walls 1 cm (one) thick and add that centimeter to the length of your walls.
2 - You could draw a floor first, and using the Advanced Resize plug-in you can edit the floor to exactly match your dimensions. That done, you can surround your floor with walls. Now use this trick from Emmanuel: "One last tip: the easiest way to design just one room is probably to draw it first with the Room creation tool, then choose Wall creation mode and double-click in the room to automatically create the walls around it."

Your solution is useful only if you are drawing a single room. If you want to draw an entire house this could be impossible with adjacent rooms and walls that cross with other walls.
Is it possible to draw walls with the inner length? Actually I only have those.
Thank you for this useful software!
This is the apartment I have to draw:
Walls have various widths: 10 cm, 20 cm, 30 cm
