Can This Sketch be fully defined?

[cdevrard]

Hey All,

I've posted on this part several times and it seems I keep going 2 steps back each time. I have the shape I need (attached file) in Sketch 1. Per the help of the forum here I've tried to go back and define the shape and I am failing miserably.  After a weekend of watching videos I've tried adding dimensions and constraints to define it, yet a fully defined sketch still eludes me. 

Thanks for any help!

Here is a picture of the actual part. The arrow shows where the "shelf" stops the rotation against the opposing part. I need the rotation to stop sooner which is why I added the 1.6 degree pie wedge in there. Does that make sense? 

Thanks!

Okay, I see what you guys are saying about the center of the arc/circle now. 

I've tried using the coincident constraint to match up those two points (center of origin and center of the arc/circle) and I am not doing something right. I fact I deleted the arc and tried making a new center point arc using the origin as the starting point. That didn't work either. 

Thanks,

Yep, my fully defined version was what is probably an old version now.

You have to be careful with the origin point, I sometimes lose it, make sure you have a point there with long left click and wait for the Select Other list.  

If you sketch with snap active in the Sketch Panel, wherever you put the curser, will highlight in blue the intended snap, confirm and the coincident will be attached.  

So to be clear - an empty sketch has the Origin Point, to snap a Line, Dimension, arc or circle to the origin, it (the Origin) will highlight as a white dot.

If you delete a coincident constraint, I think the point is also deleted sometimes, so has to be replaced, (Sketch > Point)

Importing a sketch will never be connected to the Origin, but if you immediately window select all the articles at the origin and make coincident, they should all be connected.

Might help....
