When i start a new sketch on the part plane, after I create the circles I can no longer dimension them?
Can you explain more about what's going on? I'm assuming you've activated the Smart Dimension tool? So what happens when you click on a circle with it open?
There's no response.
Were the holes created on the flat pattern?
If so, they will be suspended on all other views.
You need to unfold the part to add features as your left image shows, then refold the part.
I'm wondering if it's because you had selected the "Shaded Sketch Contour" (within the circle) prior to activating the smart dim tool. If I click on the shaded contour then I get a greyed out smart dimension.
If I don't select the shaded contour (within the circle) my smart dimension is active.
You might also try hitting escape prior to dimensioning.
