( h! R& F, o: U* \NX二次开发源码分享：从当前视图创建CSYS

比较有用哦，尤其在 PMI 视图选取的时候，自己想想！


[mw_shl_code=csharp,true] double[] center = new double[3] { 0.0, 0.0, 0.0 };
            Tag viewTag = Tag.Null;

) V4 V1 h% t) Y( K9 U: Q, ]1 W            theUfSession.View.AskWorkView(out viewTag);

            if (viewTag == Tag.Null) return;

            theUfSession.View.AskCenter(viewTag, center);

            Point3d point3d = new Point3d (center[0], center[1], center[2]);
            Vector3d xDirection = new Vector3d(view.Matrix.Xx, view.Matrix.Xy, view.Matrix.Xz);

            Xform xform = workPart.Xforms.CreateXform(point3d, xDirection, yDirection, NXOpen.SmartObject.UpdateOption.WithinModeling, 1.0);

            NXOpen.Features.DatumCsysBuilder datumCsysBuilder = workPart.Features.CreateDatumCsysBuilder(null);
            datumCsysBuilder.Csys = workPart.CoordinateSystems.CreateCoordinateSystem(xform, NXOpen.SmartObject.UpdateOption.WithinModeling);

            datumCsysBuilder.Commit();
