Add a Coincident Relation (HELP)

Hi I’m trying to add a coincident relation between the edge of the circle and the back vertex to fully define the sketch.

See image below.

Can anybody tell me where to click after I select the circle?

Thanks

Looks to me like it is already constrained.

SolidWorks will automatically add the constraint if you click on the corner when creating.

it is indeed fully defined. The circle is black meaning its defined. You can view relations and it will show you small icons on the screen or you can click the centerpoint of the circle, and the properties tab in the feature tree will show you which relations are applied to it.

If this were not the case you can shift-select or ctrl-select the center point of the circle, then the edge or point you wish to constrain it to. In the feature trees property tab, you will see a list of available relations which you can apply. Select those that apply.
