Something I recognized last week and which came to me today again …
When dimensioning with perpendicular style like this:
Click #1: top of slab of the second slab from the top
click #2: top of slab of the third slab from the top
dimension line should be one storey below … except it shows it one storey above. The dimension value is correct, but the position is off. This issue happens when you dimension downwards → not correct.
instead of upwards (third slab to second slab from top) → correct.
