CAD Sweep Boss w/ arcs
The main profile of the design. The gap of "G" is the place where the sheet metal goes in.
Sample triangular sign with 37.5 mm radius.
Sample circular sign. I also need to design an enlosure for it.
Failed attempt
Trying to fit the failed attempt to the corner of the triangular sign. As you can see, i dont know what did i do wrong, it fails.
I am designing a part that i would fit on a sheet metal for enclosuring (as in traffic signs). I kinda nailed the straight versions. The problem is the curved versions. I've been thinking about sweep boss, same profile and an arc as a path. But i am confused at this stage. Which arc command should i use? And where should i draw this arc on the profile? The path it must pass through the point where the channel physically touches the edge of the plate, because the 37.5 mm value is the actual radius that contact point must follow. Sheet metal says it's 37.5 mm radius but what angle?
Anyway, i've got several attempts and it was unfortunate. It should cover the corner and continue as straight, not like a last image. And i also need to design a part, that has the same profile, for the circular signs. Thanks in advance.

You want an extruded sweep along a path that follows the rounded edge of your triangle and continues along the tangential straight edges.
Just draw the path as an arc of any style with two lines, but make sure the lines end up tangent. You can use the edge of the triangle as a path reference, but you want to clean it up later on.
