Inspection Dimensions in Solidworks

Inspection Dimensions in Solidworks

Inspection Dimensions in Solidworks

Does anyone know where the Oval originates from on an Inspection Dimension in Solidworks?

The Oval doesn't exist in any ANSI or AMSE book that I can find or anyone I have talked with about this. I have went back to 1988 ANSI and nothing...Maybe I'm missing something here, but I can't seem to find an answer for this.

Anyone have an Idea?

I think the "inspection dimension" bubble in SW is actually derived from a DIN standard, but I don't know the number.

Here is what I finally found out.

The reason SW has the ovals around the inspection dimensions is because a long time ago a large company wanted those ovals there and it just stayed there. The company was of course buying SW at the time.

It isn't an ANSI standard that I know of or any standard that I'm aware of. Maybe a distant form of a DIN standard. That supports this option.

Scott, my interpretation, especially working wit MD, is that ovals are actually mirrored ellipses. .  When I spec. its always major/minor axis with a c/l.  This works for my job but not the standard your looking for.  I give the little gray cells a chance to work on it.
