I am trying to model the following part. However, I don't really understand how to read the part circled by a red pen. For example, what is the width and how to draw the R12.50 arc(It doesn't seem to give enough information)?
The width of each of the 4 corner raised bosses is 25mm because their sides are tangent to the R12.5 arcs.
But, Kevin is correct.
Attach the *.sldprt file of your attempt here.
Where did you get that image? That isn't from the actual CSWP is it? It would not be ethical to post image from actual exam.
Be sure to model in such a way that the Global Variables can be changes without the model going sick or causing other dimensions to change.
(In the image I exaggerated change of Global Variable "A" to show how the CSWP might request.)
Note change in Global Variables - the non-global variables remain what they were without any features failing, except for the 9mm 40° slot.
It sort of appears to be a straight cut - but I would be a bit concerned if there wasn't a multiple choice for the part volume on the answer sheet.
I would wager that whoever made up the test did not even notice this and simply evaluated the volume or mass at different values for the Global Variables and this slot ended up being whatever it was (but not 9mm as indicated in initial state of the model if the change in dimension was too much).
OK, where did you get this drawing from? Seriously....I REALLY want to know.
This part is impossible to make from this drawing without some serious guess work involved.
I know that you didn't ask for this, but here is my take on this drawing after looking at it for less than 5 minutes. I am sure that I can find more.
I was also curious where is the center of the internal R.52.
Dan, It is the task of creating a parametric model, If it was found dimensioned according to your comments, the model would not be rebuilt properly. The fact is that there are no center markers and center lines.

Both direction. Centered, not middle.
Yes, its wrong, but
So, center is on middle between top and bottom edge. Specifying the center dimension would cause the bottom and top edges to have a different average when the thickness of the element changes
Such dimensioning will ensure that the diameter dimensions will depend on global variables. Otherwise the diameters would be constant.
This detal show that is straight, But it could be shown better.
This is a checking task, we also do not see the descriptive part where there is certainly a lot of information that we lack here (in the drawings). But Dan, applause for your vigilance!
If you want to practice, and you don't have to do a specific set, here is a suggestion:
