Hi

why FME writes stroked Arcs (so there are many linepices) into DWG?

I have a very simple translation. And if I insert an inspector right before the writer there are still arcs. But in the DWG are all arcs stroked. Why? Is there a parameter or setting to give?

Thanks for your help.

The arcs in your source data are slightly elliptical (perhaps due to a reprojection?). Only circular arcs can be parts of polylines, so the elliptical arcs must be stroked.

If you send the polygons through a GeometryCoercer to convert them to lines, then a PathSplitter to break up the boundaries to lines and arcs, the arcs will be written to the DWG as proper elliptical arcs. However, the polygons will now be exploded into the boundary parts.
