# Dimensioning an arced slot places the dim on the circle not slot.

I am having a challenge dimensioning an arced slot and the KB help isn't helping. I have created a construction circle as a guide so I can have a bolt hole on the other side of the bracket. I now create the arced slot. When I go to dimension the length of the slot the dimension insists on dimensionless the rest of the circle and not the slot. It doesn't matter which end point of the slot I select first I still dimension the rest of the circle and not the slot. Is there a way to  flip the dimension to be of the slot? Or do I need to delete the construction circle first, dimension the slot, and then replace the circle?

I would suggest fully dimensioning the slot and cutting it in one feature.  Then follow up with a separate feature that will call out the hole on the opposite side.  You can use relations that will create the bolt circle to be co-radial with the slot CL radius.

Yes, that works and is what I am doing. But this does seem to be a glitch in the software if we are unable to place the dimension as we need. This is a case where "Design Intent" is for the slot radius and the location of the hole to be co-radial and we should be able to do it in one step rather than having to work around the features.

I was just hoping someone knew how to make it work correctly.

If you were to fully define the slot radius in the slot feature, then the Co-radial relation should lock the hole feature correctly.

Jim,

It worked fine for me by clicking on each end point of the construction arc, and then on the arc.

If that doesn't work for you, you should be able to delete the relations, move it off the circle, dimension it, then re-apply the relations (but you probably already thought of that).

worked fine for me - 2018 SP3.

but you did say construction "circle". I used an arc to finish the circle. if you used a full circle, I suspect you are not actually selecting the arc of the slot when trying to dimension.

Jeremy,

This might be the issue. I tried selecting the arc then the end points ( attempted alternating which one first) and I tried selecting the points then the arc with the same results the same time. In the long run I deleted the construction circle, dimensioned the arc then recreated the circle and everything worked fine.

Guess I just need to correct my order of operation and things will work out.

Thank you all.

Glenn Schroeder's workaround did work for me as well.
