Hi when I reproject dwg file from NAD27_MTM_zone_10 to NAD_1983_CSRS_MTM_10 using Csmapreprojector, it reprojects all elements of DWG files execpts Arcs. is there any setting that handle this issue?

The CsmapReprojector should be able to reproject the arcs, but in doing so will convert them to elliptical arcs or polylines, depending on the amount of distortion in the reprojection. You could try using an ArcStroker before the CsmapReprojector to force the conversion to polylines.

Thanks Dave

It works (however the challenge was that ArcStroker could not handle texts. For this reason I used CsmapReprojector for rejected again)Arcs2
