how can I read points that created curve in dwg

Hi ​@mkh.rcjy ,

I would say a Transformer Chopper with maximum vertices = 1, will gives you points of the curve.

In addition to the above, the ArcStroker and ArcEstimator are helpful when deal with Arcs (Curves)

The ArcStroker will convert the Arc to a polyline, and the ArcEstimator essentially does the opposite - takes a polyline and estimates an Arc that fits
