I'm not a CAD user, but measuring is something I know a lot about.
I don't see a way to click on an object and then look in a place (first place I tried was "object properties") to see the measurements of that object. Flamingo told me that the hex is 0.997cm high, not exactly 1.0. I don't see a way to look this up. When I use the measuring tool (pictograph of a measuring tape), I do get a precise answer. However, it will change by a couple hundredths depending on the zoom level I am at. So if I am trying to tell the difference between 1.000 and 0.997 using the "measuring tape", it's frustrating that I get a different answer at different zoom levels. But while I was just messing with the tape, I also noticed that it gives me the angle measurement from horizontal, as well. It's not right at 0.000 degrees. I tried setting it up to "snap to grid" but at this red hot minute that isn't working. I will come back to this later tonight.
But for now: How do I look up the properties of an object so I can see it's length, width, and angles? (without using the measuring tape tool). I looked under every icon and menu bar. I assume I'm just missing it.
