Importing Points Part I

We know that there are several ways to import point data into Autodesk® Civil 3D® 2006. We can...

1. Import Points from an ascii file.
2. Use LandXML to transfer the points.
3. Use the Autodesk® Civil 3D® 2006 – Point Conversion Utility

Not everyone knows that methods 1 and 3 will give us better results.

Why? Well unfortunately the LandXML format stores the point's number as

< CgPoint name="PointNumber"... >.

When the LandXML point data is imported into Civil 3D it is read as the Point Name NOT the Point Number. It will be handled as not having a number and will be automatically sequentially numbered.

Note: It is not possible to Use the "Import Data from Land Desktop..." (IMPORTLDTDATA) command to import the point data directly. This only supports the importation of Description Keys, Surfaces, Alignments, and Parcels.
