I am a green ArcGIS user so please bear with my poor nomenclature and rudimentary understanding of the software........
I am attempting to export to CAD a contour shapefile I have derived from LIDAR imagery. Once exported I bring the contour DWG into ArchiCAD, drag ' drop, boom it opens. All good.......except:
Any curves are broken down into thousands of single small co-joined lines, and unlike Autocad I don't have an effective-efficient way to polyline edit......make continuous sections into single polylines or splines as they'd be referred to in ArchiCAD.
Is there a way to set up my shapefile, edit or geoprocess it prior to export that will net me what I am after?
Thanks in advance!
