Incorrect measurement results

[madcamperx]

Hi,

This may be an easy fix but I have not found the answer anywhere. When I import a stl file into my fusion 360 and use the measure tool(measuring in mm), I get a very large measurement for what should be a very small distance. I think it has something to do with how my grid is setup but I cannot get my grid set in a 230mm x 230mm pattern(size of my 3d printed bed). It looks like every square is 230mm which would account for why the measurements are so off. The inside diameter of the base of this object should be 49mm, not 485.752mm like fusion 360 is showing. I had been using selfcad to measure(until my trial expired) and it's measure tool method(point to point) was the same as fusion 360 but its calculations would measure correctly. Is there anyway to setup my fusion 360 grid to match that of my printer bed, 230mm x 230mm ?

My current grid settings(I've also tried reversing it to be Major Grid Spacing: 1mm and Minor subdivision: 230

This should have nothing to do with the grid. Its likely how you are opening or creating the file. When inserting that mesh if its set to MM on insertion it will insert correctly.

Are you using File>open? If so, which i belive you are, it will scale the units improperly. The best method here is to use Insert>Mesh

Thanks! That was it!
