AutoCAD Map 3D

[#1]

When using the mapdist command the measurement is different from the actual line that I create. The map coordinates and the maptrack coordinates match. When I open a older drawing there is not an issue. Did I somehow change the origin of my template.

Any suggestions thanks

Here is sample from the command line

Command: _mapdist
Specify first point:
Specify second point:
Distance = 12.7513 (Foot)
Azimuth = 38 degrees (forward), 218 degrees (reverse)
Delta X = 15.0000, Delta Y = -0.0381

DIST calculates the distance between two points in space.
MAPDIST calculates the distance as measured on the earth's surface.

If no coordinate system is assigned to your drawing, DIST and MAPDIST will return the same values. If you assign a coordinate system based on a map projection for your DWG, then you will of course see a difference between the two measurements.

Here is an example. I assigned HARN/WO.OR-S to my drawing, drew a polyline, and measured the distance of that line using DIST, and then MAPDIST. Here are my results:

DIST
Distance = 7.8132

MAPDIST
Distance = 7.7772

I hope this makes sense

When drawing lines there is a difference between the line drawn and the mapdist measurement. Is there a way to draw the line so both distances are equal?
