Is there anyway to read the featId attribute of a polyline and assign the elevation to the polyline? All the polylines are at elevation 0. Is there a lisp routine to do this?
PS: I do not have the shp file from GIS only the AutoCAD drawing with the polylines already created and their featId.
Thank you in advance for any input.
A few years ago I wrote a routine for a customer who wanted to do exactly what you describe. If you send the drawing, I can modify it work work for you.
You may still be able to use a Mapquery to query the polylines from that file and add the featid field as the elevation. Find instructions [HERE] in post #3. Ignore the expression for converting the elevation and only use the elevation stored in freatid.
