Newbie here, making great strides forward with some help.
I have a long rectangle with an angle at the bottom. When the angle is measured in SU, with the added angle tool, it is 82.1 degrees.
I made the rail into a component and sent it to Layout. I added the dimensioning and also measured the angle at the foot. It measured 84 degrees.
Which dimension do I rely on?
When the rail is finished the bottom angle will be resting on a ceramic floor.
