I'm looking for a method for reshaping parcel polygons in large-scale database. I am dealing with cadastral data as shown in the picture and I need to convert the vertexed curves to true curves to reduce the vertices number and improve the performance during the editing process. The polygons originated from CAD.

If you have at least a STANDARD licensed install of ArcMap then you can use the Smooth Polygon tool in the cartography toolbox. Be aware that you cannot create Bezier curves if your source data is a shapefile.

If the line can be represented with a single curve then I think it will do this otherwise it converts it to a set of curves so you may not get the desired reduction in vertices, just something to be aware of.

  • I think it best answer if asker wants to use a tool for this issue if you just use arcgis software. Without this metbod you should edit manually all vertices.
