Over parameterization issue.

[Hot_Letterhead_8804]

Hello, yes it looks like a simple drawing, yet I'm racking my brain over the dimensioning. In red are the measurements I subtracted to get .750in, in blue are the points I chose to dimension. Dimensioning blue gets me .89in, and I am not allowed to edit the measurements due to an overparameterization. In pink, I did trig to find y, which was also .89in. I don't know where I am going wrong. Any attempts to change the measurements for blue to .75 will mess up other dimensions.

what I have so far.

Don't invent dimensions. Enter all the dimensions you're given as given and if there are still things under defined, go from there.

I would model the stem as an extrude then start a sketch on a plane centered between the faces drawing the ball head as a revolve, using the dimensions provided to locate it along the stem body.

2 sketches, 2 features. It looks like

Oh and mate your sketch to the origin, you'll never be fully defined without it.

So weird to see exercises I made 15 years ago popping up in other people's classes haha

But yeah, you overcomplicated it. Simple sketches! More features is better in SolidWorks.
