OsnapZ

I need our points to use point elevation for when drawing lines and 3d polylines, however, I need to be able to check the distances between points, not the slope distances. I set the variable OSNAPZ to 1 which is supposed to use the elevation of the UCS (which is set to 0.00), but instead when I take a distance it uses the elevation of 0.00' for the first point I select (using node) and the point elevation of the second point (using node) which is the slope distance.

When I draw a line between the points with OSNAPZ 1 it is flat at elevation 0.00'. Is this a Civil 3d problem or is there something I am missing?

That's odd... when I set Osnapz=1 and use Dist between two points I get the horizontal distance, not the slope.

If you want, you could try this. I wrote it before the Osnapz variable was introduced.

;; returns horizontal distance regardless of z values LPS 2008
(defun c:di (/ pt1 pt2)
(setq pt1 (getpoint "\nHorDistance  Pick first point: ")
     pt2 (getpoint "\nPick end point: " pt1)
     pt1 (list (car pt1) (cadr pt1))
     pt2 (list (car pt2) (cadr pt2)))
(princ (strcat  "\nHorizontal distance = " (rtos (distance pt1 pt2) 2 2) "'"))
(princ)
)

Thanks, I'll give it a shot. It's not just my computer, 3 others in my office have the same results.

Give my DIST replacement routine a whirl.

Maybe it's a 2010 thing...
