wall lengths change all by themselves when they lock together

[teppup1]

I am continuing to try and draw a floor plan of my house. Unfortunately when
I put together exterior walls they change length. This happens even with
protection turned on and snap & glue turned off. Extremely frustrating.

There appears to be no problem with the video drivers etc on my laptop. The
size does not change when I move a shape, just when I put lines together

Hello Teppup1--

Let's see, this issue has been lingering about a month. Phew!
I have a suggestion which ought to avoid some of the wall length resizing.
Basically, since you've measured outside dimensions, when you place your
walls, always, I mean always, keep the reference line to the outside. Then
when you place the next wall, always place the connection pins on together.
Always! As you progress around your structure, the reference line will form
a continuous band (until you add doors and walls, of course). This avoids
the resizing due to snapping. It's OK to maintaining the snap and glue
functionality, you won't need to disable these features.

There is one potential issue that I see. Depending upon your wall
thickness, e.g., 250mm, the inside edge of the wall will not be on grid,
since that is typically no less than 100mm. The reference line tends to
gravitate to the grids. (Really, what you're placing is a 1-D line that has
the "wall" shape grouped with it.) I doubt that you want to remeasure on the
inside so that the wall placement is done with all reference lines toward the
inside of the house rather than the outside. That way, the inside edge is on
grid, and as long as connector to connector joining is maintained, no
re-sizing of the reference line takes place. But the outer wall will grow
and shrink at corners.

Sorry for the long explanation.
