Automatic contour label for AutoCAD.

You can label your contour elevations automatically with the help of AutoCAD dynamic blocks functionality (used to its limits). Please find an example of such annotation label in the dynamic block ContourAutoLabel in the CAD block catalog.

If your contours (polylines) are placed in "their" height (Z-coordinate), just use an osnap mode (e.g. NEArest) and insert the block ContourAutoLabel on the contour polyline. The label will be automatically aligned to the direction of the contour, its Height attribute will be set to the Z-coordinate of the insertion point, the value of the coordinate (rounded to one decimal place) will be centered and background will be masked around the label text.

To suppress the frame use the TFRAMES command. To disable the shaded background use the FIELDDISPLAY variable (the background is not printed anyway).
