On Feb 25 I asked for a way to change AECC-contour elevations. The answer proposed was to use vlax-get-property. Made sense, so I finally got around to trying it today. It seems that (vlax-ename->vla-object . . .) will not recognize the AECC-contours. Is there some supplemental info that I need to incorporate into vla to recognize them? Or where is there a detailed description of the object? RS
