Wedge attached, (wedge)(wedge) don`t know what size you want or what orientation but it`s quite quick and easy to make this sort of thing.
If it`s what you need then I`ll go through the procedure for you, if not let us know exactly what it is you want.
Basically all you need do is create your rectangle and then delete one of the sides, then go to "Lines > Angle" and set the degrees you want and a length longer than the rectangle and then just click on where you want the angled line to start, you might have to change it from a positive to a minus value to get the direction but that`s seconds to do, then go to "Utilities > Trim Extend > Quick Trim" and just chop off the bits you don`t want.
Now go to "Surfaces > Extrude a Curve" and just select the geometry you have created and fill in a distance in either the positive or negative direction for the size you want your solid.
Sounds a lot but it`s a couple of minutes tops![]()
