i have inserted the draft and my solidworks sketch. please help me thank you
Accepted answer
You’re missing the .964 height constraint to the edge of the . 851 fillet.
There is no dimension on the original drawing that constrains the .851 fillet horizontally. I would assume the angle of the surfaces leading to the .851 fillet are similar. So once you place the .964 constraint, get the angle of that surface and use that to constrain the other surface.
The original drawing is also missing the diameter of the .125 recess on the bottom. It looks like the .531 holes are centered between the recess and the OD. That would make the recess 8.500 diameter.
In my opinion the original drawing is not a very good example to follow. The dimensions are crowded and poorly located. Some features are not dimensioned, yet other features are over dimensioned. These issues are what lead to your inability to fully constrain the sketch. These issues would also prevent successful manufacturing of this part because the drawing has not conveyed the full intent of the designer.
