I have been trying to get two boards to be 10’7.5" apart (measured from the outside edges). And was having a hell of a time with the distance measuring wrong over and over again. So I finally built in a measured line and just snapped the second board to it, but when I went to measure this again it was still off (depending on where and how I measure it).
Everything is snapped together, and it does not matter how much I zoom in, this is single continuous lines. but measuring it with the tape measure I get one 16th too many.
As @Box says, please upload your model. Trying to see 1/16 inch out of 10’ 7 1/2" on a screen shot is essentially impossible, so I can’t tell which of many possibilities is to blame.
Thank you both for taking an interest. I will assume by model you mean the save file.
In Sketch.
Ah, that is a thought, the objects I am working with do have a depth, but I have done everything in “Top” down view, so everything is on the same plane. Maybe it is measuring to the bottom edge, but that would be really strange behavior.
Part of the problem is that the one on the right is higher than the one on the left so you are going to get bad dimensions. Orbit around to look at the model from the side. Switch to Perspective to make it easier.
I would suggest that you do two things. First, set Precision as high as it will go–1/64 in. in this case. This will make it easier to see discrepancies in dimensions. The other thing is to place the dimensions while working in a perspective view and zoom in to the corners when anchoring the ends if needed. Working as you have been means that the poor alignment of the groups isn’t visible and you can be easily dimensioning off the wrong endpoints resulting in further errors.
