Foundation Glitch

[wr.marshall]

I am using the exact same Foundation various walls. The Dimension is 800mm wide. When creating a foundation plan though, some are coming out as 805mm and others 800mm. Dimensions are set to use project units, and project units are set with one decimal point ie 1234.5

You are using Retaining Structural Usage  and the Host Walls are different thicknesses.

Change the Structural Usage to Bearing -- or make the Walls the same

that makes sense. I'll give that a try

[wr.marshall]

@barthbradley changed it to bearing as you suggested, but the dims  are not related to width specified.

Where is it specifying the 600

Wow. That is bazaar. Never seen that before.  Where did you get that Footing?  I was able to copy a different one into your Project from another Project and swap it out for that funky one.

Please share your non funky one. Maybe a fault with the templates as project started from fresh
