Question

How do I call out a symmetrical part on a drawing?

I am dimensioning a bar with holes and am searching for a symmetrical symbol for the 240 dimension and can't find it.

If the centerline is in the view, is it assumed that the dimension is symmetrical?

If you select your dimension, RMB, Properties, and pick the Dimension Text tab, you can add text. Pick the Symbols button and the symbol you want is there. HOWEVER, if you really want to do this properly, according to standards, you need to explore all the gtol (Geometric Tolerancing) functionality within the Part and Drawing creation environments. You would probably set a central dataum as a gtol reference and go from there.

On second thought, there is another thing you could do with your part. In the drawing Insert a Geometric Tolerance. Then if you pick the bottom horizontal edge of your part as the reference you can attach a gtol box to your dimension with a tolerance.

Yes, but only if you'd delete the 120 dimension.
