# Forcing an arc length or angular dimension to one side

Wasn't quite sure how to title this one...

This happens to me with both angular dimensions and arc-length dimensions.  In the pic below, it's an arc length.  How would I force the dimension to the other ("bottom") side of the circle?

With angles, say I have a 30 degree angle.  Sometimes, Solidworks wants to show it as a 330 degree angle.  Still correct, but not what I always want.  How is that fix forced?

Thanks.

It's usually a matter of where your cursor is when you initially click to place the dimension.  Once it's placed wrong all you can do is delete it and try again.

Hey Glenn

I hope the dimensions can be rotated to the required place, it allows 360 degree rotation. so will it solve the above problem?

Good idea.  Drawing attached.  Thanks for the help!

There is something weird going on in SW with the arc length value. I was trying to duplicate your dimension and mine kept showing up on the bottom, but the values were different than yours. When I create the arc length dimension for the complete semi-circle from your Base-Flange3 Sketch1 it shows 32 5/64. And after messing around a bit I figured out that your dimension was created with those intersection points and the OD of the bend, and the value came out to 32 21/64. As far as I can tell these two methods should be identical, because the intersection points coincide with the endpoints of the arc from Sketch1, and the OD of the bend is the same as the arc from Sketch1. So I don't know why the values come out different. But I think the correct value is the 32 5/64, because 32 21/64 is more than half the entire circumference of a 20.5 diameter circle.

But my suggestion would be to dimension to the arc in Sketch1 instead of using those intersection points.

And as far as your question about choosing the side, I don't think there is a way. I think maybe it always puts the dimension in the section that is less than 180 degrees.

Hi Jamil,

How exactly do I dimension to the arc in Sketch1?  Thanks.

When you are in the drawing go to the tree and expand Drawing View5 and find Sketch1 in Base-Flange3. Then right click on it in the tree and choose show. Also make sure under the View menu you have sketches shown (you may need to uncheck Hide All Types). Now the sketch should show up on the drawing and you can place the dimension by selecting the cornes and the arc. If the intersection points get in the way you can delete them and put them back after you have placed the dimension if you want them shown. Once you have the dimension done you can go back to the tree and hide Sketch1 again so it doesn't show up on the print.
