If I want to create a triangle with the three cornered of exact angles I have to work out the lengths and set the lengths correctly. It would be nice if i could select one of the corners and simple type in an angle. This is the same with roofs and wedges, it would be really nice simple to be able to chose the significant angle and type in a value
What I am actually doing in my case is making a camera mount that I want to be 5, 10, 15 and 20 degrees. My idea being that it will have a series of hole though which a locking pin can be places to hold it at the specific angles. Like I say I can do this using measurements do the lengths but the ability to select and angel and simple type it in.
