Fillet dim 3

[ctopher]

New one for me.
I added a dim R .50 to a corner. It passes near a tapped hole.
When I dimension the corner where it meets the tapped hole, it shows the following dimension:

If I select the fillet where it does not meet the tapped hole, it's a normal radius dimension.
Anyone seen this before? What does "RM R.50 x 1.0" mean?
(The position of the dim is for illustration here only)

I didn't post in the Drafting Standards forum because I thought it would be a SW issue.

I think you will find that RM signifies Mean Radius. It's possible that the fillet either breaks into, or is bisected by the tapped hole.

itrans,
Yes, it does. Interesting though, if I add the tapped hole after the fillet, it does not dim this way. SW sees the fillet break thru the hole after it has been filleted, not before.

By adding the fillet after the hole, the fillet is probably propagating itself around the hole.

By adding the hole after the fillet, the hole is just cutting through the fillet ... no propagation.

 

[ctopher]

CBL,
Yes, I agree.
So when propagating around the hole, what does the "x 1.0" in the dimension mean? (RM R.50 x 1.0)

I have no idea!

Can you post a couple of close up images of the area?

RM .50 x1.0

RM = Mean Radius

I believe the [.50 x1.0] is the dimension of an obround - due to fillet bisecting and propagating around the hole, effectively becoming obround.

 

[CorBlimeyLimey]

That was my thought also ... but I can't reproduce that effect from Chris's image.

 

[ctopher]

DPeyton,
That makes sense, but I can't anything on the feature that represents the "x1.0".
Maybe a slight bug with SW?
As I wrote earlier, it only happens one way and not the other.

If you edit the dimension or look in the property window, do you see the variable name for the 'x1.0' ? Maybe that is a clue?

It shows as "RM<DIM>x1.0".
Interesting, if I right-click on the dim, then change it to a diameter dim, it changes it to "RMM 1.00x1.0".
The dim text still shows it as "RM<DIM>x1.0", but displays the "RMM...it will not go away. If change back to show as a radius it still shows RMM.
A bug I think.
