How can I make a wall keep the measure without the wall itself?

[Takuto_90]

So, I measure a wall of the room (from the inside of the apartment) and write it down... but when I'm actually trying to make it, the measure is somehow wrong, because it does count the walls. When I create a dimension later to measure the wall, it's always shorter, as if the measure of the wall was taken from the middle of inside my walls. [#-o]
Like, one wall is 96 inches, but then the dimension from inside says 93.5 (my walls are 5 inches thick).
Any way to fix it?
It's not a big problem, but in an apartment like mine with many walls, inches after inches it won't square up at the end. Kinda hard to explain the whole situation, and maybe there's a setting somewhere... Thank you.

Your observation is right: walls are measured at their middle. So either you take wall thickness into account when you draw walls, or you draw rooms first following this tutorial for example.

Hello,

First of all, thank you for this great piece of software.

I have tried using SH3D for creating floorplans for 2 houses so far however always seem to get stuck trying to set exact dimensions with variable wall thickness.

I try to transform an existing floorplan on paper into SH3D. I cannot use the image as a background and overlay walls on them, I want dimensions to be exact and the existing paper is warped and has bad quality (copies of copies).

So I try to go by the dimensions specified on the existing paper. However, it seems impossible to do this with the current interface unless I am missing something fundamental. Let me explain the simplest use case below, so hopefully somebody can provide some feedback on this:

I draw a rectangular area, then select the wall cursor and double click on the area, the walls are automatically created surrounding the area. One of the walls needs to have a different thickness, so I edit the wall and change the thickness. The wall now changed thickness but does not adhere to the area anymore. It is still connected to the other 2 walls and joins them at their ends, leaving some empty space between the area and the wall with reduced thickness.

So I'm kinda stuck here (problem 1); I know I can move the wall, but how to to make it adhere exactly to the area again without having to make manual calculations (area right x coordinate(wich is not present) + wall thickness / 2 ?) ? Is that how it is supposed to work? Note that there does not seem to be magnetism or visual alignment indicators when moving the wall manually to the area.

I hope this is somewhat clear, any help would be appreciated.

Thanks

Yes it's how it's supposed to work. If you want to move the wall more precisely, you can zoom in and use the arrow keys. Note also that the thickness of new walls can be set in preferences pane.

Thank you for your reply.

Understood, that's how I am managing now, but not it is not really an ideal interface:

- really hard to see visually when exactly walls connect with each other: I'm manually zooming in to maximum and visually align, hoping this is correct
- no magnetism: would be nice if walls could snap together while moving.
- connecting walls: only endpoints can be joined, what about T joins or multiple joins at the same intersection.

Just a few ideas, I can only hope this will be considered, I saw some other posts about this as well. I think these are really missing for an otherwise feature rich application.

Thanks
