I am having trouble figuring out how to establish Datum B (see attached). It creates that midline the red arrow points to, but it seems to be a line and a point. Does anyone have any advice on how to create that midline from a straight and curved feature?
UPDATE: SOLVED. See
neil.challinor's reply/following comments for how I created a tangent line from a circle point.
It has to be a point ? I can see that getting wonky. You have a line and a tangent point. Anything mid point created in the center would probably be mid point perp to B. In this case, B will only be a 0.0 and will not control rotation as it cannot. Midpoint from C and midpoint from D will then create a " line " for rotation that will be used as CD. I would consider creating CD , rotate to that then take single point on both "sides" and create midpoint for B. Of course all the target points are coming from each other so what you going to establish 1st ?

I establish the bottom line of B first since most of the basics come from there. The only ones that I cannot get from there are the target points for Datum A. I could rotate to C-D but I don't think a point as a secondary datum is acceptable. Thats where I'm stuck.
