First you should add the radii to your part, then dimension in the section view.
The fillets are in the model already. I am trying to figure out the best way to show on a drawing, the difference between a constant fillet and one that is tapered.
R .375 + DFT
or + DRAFT
I actually like the "constant" - there may be a better term but I couldn't think of it off the top
That looks good. I could not find a drawing that shows an annotation like this on a radius. I’ve seen drawings with a linear dimension labeled +DRAFT or –DRAFT or +2° or -2°. In my drawing, wouldn’t it be better to call out R.375 -DRAFT since the fillet is getting smaller?
The part I’m working on is more complex and will have a section view cut horizontally through the box. I will label the dimensions in the section view R.XXX +- DRAFT and keep the 2 fillets labeled CONSTANT so there is no confusion.
Since I will have lots of dimensions, maybe it would look cleaner if I could just put a note in the view that reads:
ALL DIMENSIONS IN THIS VIEW ARE
SHOWN AT THE SECTION CUT
LEVEL. ALL RADII ARE DRAFTED
UNLESS LABELED "CONSTANT".
Does that make sense?
Thanks for the input!
It really depends on the application.
It is important to look at how will the manufacturer be making the part. For example, a machinist might be most interested in the smallest diameter so he can specify the right ball endmill for the job.
Extra dimensions that they will not use in their work might be more distracting than informative.
