"CL" attached to a centerline
"CL" attached to a centerline
(OP)
When is it appropriate to attach a "CL" symbol to a centerline? Is it ever nessesary? Is this part of a standard somewhere? Does anyone do this on a regular basis?
Oh the joys of writing CAD standards.

So I have features on the outside surfaces of the part that must be dimensioned from the round feature in the center of the part, but you cannot see the round feature in the side views where these other features are.
Hope that isn't too confusing. Should I show the CL symbol on the side view centerlines for clairity or is it enough to have just the centerline and a center mark in the top view? I would post a pic but I cannot due to proprietary rules. If you need one perhaps I can sketch something to illustrate.

Using a centerline font thru the axis of a circle feature without the CL is correct.

If possible, show the hidden geometries in phantom lines so that the feature can be identified.
An irregular-shaped piece also has a centerline, so showing the centerline of the circle only would be misleading if it were not centered. In that case, I'd show the centerline of the workpiece with a visibly longer line than the centerline for the other features.

I've done some civil work in shcool so I know what you mean and agree that would be an aceptable application, but I should have specified this is a mechanical part so this really doesn't fall into the same catagory.

I would only use CL if for some reason the part needs claryfication, I would use CL to indicate center of the part. It is sometimes useful for the machinist.
