True R in Iso Views

[aamoroso]

I want to show a diameter dimension in an ISO view, I can only get a True R dimension. Is there a legit way to get a diameter dimension other than faking the dimension.

Well, that should be a legitimate dimension.

You can either edit the dimension's properties or else get an elliptical shape that will not be able to be dimensioned, depending on what you're looking for.

I normally see this when a part has been drafted and has a radius applied around the corners. The true radius is noted in the dimension. If I wanted to dimension the curve represented by the drafted radiused corners coming to the top of the part, this would actually be an elliptical profile. The radius is still the same over the two surfaces, so I would think the elliptical call-out is irrelevant. Perhaps you're doing something else?

yes and no,

On our Sheet metal drawings we normally show an ISO view for reference. This particular part is symmetrical except for two holes, one is .250 dia and the other .219 dia. I would like to put the .250 Dia dimensoin on the ISO view to help distinguish which direction the flat part is formed and I would prefer not to put a True R for simplicity sake. The production department is full of temp employees and turnover is high, I cannot depend on everyone to know what True R stands for. I know this is basic stuff but in the world of JIT manufacturing and and the more for less era this is something that has to be dealt with.

In that case, I would think you could right-click the dimension and get rid of the extraneous notation. (Manually, of course, but it didn't sound like you had to do this a thousand times.)

2 possible solutions:

Make a linear dimension between diametrically opposite points on the arc

-OR-

Make a custom property in the part file that references the diameter dimension (this can be a sketch dim or reference dim, driving or driven). In the drawing, add a note that references the part's custom property. I do this occasionally to create slot callouts and chamfer callouts.

there you go, I knew someone would have a nice work around, I like the opposite points idea.

Good job Tick
