@st32-22 

Do you see in @CCarreiras image lines that should be constrained vertically or horizontally that are not?

Well, add the missing Horizontal and Vertical constraints.

Doesnt look fine... is missing something here:

Well, in mechanical design, is not enough to look fine, the important is to have the correct information, unless you are studing marketing or design...

Edit Sketch1.

Click and drag some of the lines.

JDMather_0-1685377989249.png

See any unexpected behavior (like lines without Horizontal or Vertical constraints)?

No.

 

Making sure that the model is accurate, fully-dimensioned, and manufacturable are critical skills to be a successful designer.  Skipping those steps may make a nice picture, but cost time, money or frustration from other CAD users, the manufacturing floor, or the project management team. 

 

Everything that the operator does from the first feature in a part through an assembly, and the final 2d or 3d documentation is dependent on the previous steps.  If the first few steps have bad or unstable data, then everything that follows is unstable, untrustworthy, or just plain wrong.  The House of Cards essay by Walt Jaquith is directed more at assembly issues, but the get-the-basics-right theme is important.  https://forums.autodesk.com/t5/inventor-forum/is-inventor-really-useful/m-p/1332818/highlight/true#M...1

SpaceX Starship super-heavy booster and launch pad "looked fine", till they tried to actually use it for it's intended purpose. Crash and burn.  Do you want to repeat the class?

OK, i think you're fine, i think you have just enough to pass.

Anyway, you will not have much time to learn this properly, but as you said, you just want the minimum skill to pass... so, youre good to go.

Good luck.
