Newbie wants to dimension to the center of a line

[fuerst]

How can you dimension to the midpoint or center of a line? I have a lot of steel details that need c to c dimensions, not from the edge of the beam.

Thanks,

If you constrain a Point, Hole Center to the midpoint of the line you can
dimension to/from it.  Or draw a construction line to represent the
centerline instead of a Point, Hole Center.

The way I normally do this is to add a centerline
to the columns using the "Centerline Bisector" annotation tool and then
dimension to these centerlines.

Wait... are we talking about dimensioning in the modeling environment or in
the drawing environment?

Ooops, drawing/detailing/.idw environment guys.
Thanks, I used steel creator for the model/sketch, I also added more axial work planes for constraints and such but the only details I can get in the drawing environment is the edges of the beams in the top and side views. (Edited by Moderator)

Like I said earlier, the best way I have found to
dimension to the centers of beams/columns is to use the Centerline Bisector
annotation tool to add a centerline to the beams/columns and then dimension to
the centerlines.  Or, perhaps I have misunderstood exactly what you are
trying to do.

No, just a (edited by moderator). Adding information to get something that should be an option is not progress....
I appreciate the info though, just ranting a bit. 1st

LOL.  I had not seen (Edited by moderator) used before so I had
to look it up.  I am surprised it hasn't been used more often on this
board.
 
As for the added centerlines, our drafting
conventions require us to show a centerline in such instances in order to
clearly denote that the dimension is truly to the center of beam or column (or
whatever).  So, I have to do it regardless of whether or not the dimension
requires the added lines.  And, the Centerline Bisector tool works quite
well and is pretty painless to use.  But, if you don't need/want the
additional centerlines, I would agree that it is a (Edited by Moderator).
