Is anyone familiar with the following symbols that look like a 'D' with a plus and a 'D' with a minus inside them?

Never seen them before. Bet they are +draft or -draft?

 

[airion]

That was my guess. If anyone out there has seen it and can confirm that please reply.

I've seen circles with +, -, and N in them for + draft, - draft, and No draft.... never a D with them inside

These are Plus Draft and Minus Draft symbols

Hi,


May be draft angles for the features? Jus check it out.

The plus draft would mean the draft angle will increase
the dimension as it goes away from the side the
dimension is on and decrease for minus draft.
