Driven Dimension

[Anonymous]

You can in the Sketch5 there is a Driven Dimension (1.750). I tried to change it to Drive Dimension many times but it is not responding favourably. Please tell me why.

Hi!

Of course you can't take the "Drive Dimension" status.
Think a little bit more.... The geometry is constrained (even before that dimension), therefore, any dimension you apply later, always be a "Driven Dimension".

Tip: Why you just don't go have some inicial classes in Inventor? Certainly you will gain a lot of time, instead to have doubts from 5 to 5 min....

The center point of the half-circle arc in your extrude sketch is coincident with the midpoint of that projected edge. If you want the cut centered on that edge, no further dimension is needed. If you want it off-center, you'll have to delete the coincident constraint between the projected edge mid-point and the center point of the arc, and then reconstrain the arc center point to anywhere on the edge except the mid-point (by default, the midpoint appears as a green dot when you hover over it).
