Just received the attached surveyor's drawing. It's in decimal units. When I measure from point A to point B, I get an answer, which states 315 units in the X direction and 153 units in the Y direction but, the "distance" is shown as 1208. units. I would have assumed the distance is the hypotinuse of the X and Y sides of the right triangle. The measurement, also, states there is an angle "from" the XY plane of 16 deg.'s.
I would have expected a plan view surveyor's drawing to be 2D with a 0 angle from the XY plane and, also, expected the decimal measurement to match the numerical amount of the Architectural or Engineering. For example if the Arch. units measure 100', the Decimal would measure 100 units or, possibly, 100' x 12" or 1200 units.
Could someone look at the attachment and offer an explanation?
Thanks,
