Error: The geometry is not Z-aware

ShaningYu — Mon, 24 Jul 2017 14:06:22 GMT

In my ArcObjects projects, there is a function to Insert a polygon feature from a Source FeatureClass into a Target FeatureClass (fc_Target). The related code is below:
IFeature f_Target = fc_Target.CreateFeature();
f_Target.Shape = f_Source.Shape; // f_Source - feature of Source FeatureClass; Got error
However, it throws an error: The geometry is not Z-aware. Then, I found that the fc_Source is a type of PlogonZM, while the fc_Target is type of Polygon. How can this problem be fixed? Thanks.

The reported error was gone with the code below:

            IZAware zAware = (IZAware)f_Source.Shape;
            if (zAware.ZAware != false) {
                zAware = (IZAware)f_Source.Shape;
                zAware.DropZs();
                zAware.ZAware = false;
            }

IZAware zAware2 = (IZAware)f_Target.Shape;
f_Target.Shape = f_Source.Shape;

Thanks for your review.
