Sketch is not contrain

It's very hard to solve this without access to a public document, but…
I can see that there's something done with offsets. If you've trimmed them, sometimes you're left with stray points which may be coincident with other vertices, but without being properly constrained. I would look carefully at each vertex and see if there's more than one point there.
It looks like offsets might be involved. If you’ve trimmed them, you could end up with stray points that overlap with other vertices but aren’t properly constrained. I’d carefully check each vertex to see if multiple points are in the same spot.
Thank you . the radius on a sketch was duplicated . . . i found and corrected .
It looks like your sketch isn’t fully constrained even though you’ve added dimensions. Make sure to check for missing geometric constraints like coincident, horizontal/vertical, or tangent. Sometimes, lines may not be fully connected or there might be small gaps. Try dragging parts of the sketch—if anything moves, it’s still unconstrained. Also, check that everything is anchored to the origin or a reference plane. Hope that helps!
It sounds like your sketch might still be under-defined despite having dimensions. Keep an eye out for missing geometric constraints like perpendicular, tangent, or coincident—those are easy to overlook. Also, try gently dragging parts of the sketch; if anything shifts, it’s a sign there’s still something unconstrained. Make sure your base geometry is fixed to the origin or a known reference point. That usually helps lock everything down properly.
