Exercice intermediate sketching : don't understand my miskate

MathMath Member Posts: 9
Hello,

I start to use Onshape since a few month, mostly to design parts and print it with my 3D printer, for personnal use (repair of objects). I have a few experience with SolidWorks and Catia, so I have already done some basic parts with Onshape.
But as I want to start to make more complicated parts, I decided to make the free online available courses in order to take in charge correctly Onshape and learn useful tips.

I have some difficulties with the exercice "Intermediate Sketching" : if I apply all the dimention constraint like slide 7, my sketch is overconstraint. I compare my sketch to the corrected sketch from Onshape, but I don't see any difference in the applied constraints. See attached print screen : left my sketch and right the Onshape sketch. If I apply the remaining dimention constraint radius 125mm to the arcs, my sketch become overconstraint.

So I realy don't see where is my mistaske : some could help me ?

Thank a lot !

    This should allow that dimension to be added. It might have been added by the system based on how/where you initially added the geometry.

    Hello,

    Thanks it's works. When I have compared my sketch and the Onshape corrected sketch, I have missed this vertical contrain I have in addiction !

    Thanks,
