Not fully defined?

My uneven sided hexagon has all sides and angles defined but is still not fully defined in the right plane. What am I missing?

    You probably haven't told onshape where you want the hexagon located relative to the origin or 2 planes or other geometry in the model.

    MDesign is correct, and this is probably one of the most reoccurring questions about sketching that trips up the novice user. You have got to "anchor" your geometry to the origin (it's the only reference point that is fixed in 3d space). Do this with constraints, or dimensions. The good news is that it can be done at any time, but I find it's just easier to do it from the start. Try to make this a habit (this is good practice).

    P.S. you don't have to fully constrain sketches in order to make parts - but if they aren't, it can cause issues if you come back later to do edits to the model. Good luck

    Can anyone make me a hexagon starting in top plane origin point with alternating side lengths of 27mm and 132mm that is fully defined?

    Is this what you're looking for?
