Civil 3D Points Names and Point Numbers.

[yangcheng2008]

I'm trying to import a GPS coordinate file where our Surveyor has used both Points Names (Alpha-Numeric) and Point Numbers. see below. I have setup a Point File Format for Pname, North, East, Elev and RAW Description, to import this comma separated point file. The problem is that Civil 3D does not want to seem to use a numeric point name as a Point Number, instead the number is used as a Point name and Civil 3D assigns a Point number from the next availible point number. Is it possible to automatically, when the Point Name is a numer only to also assign it the same value as the Point Names?

I would really want Civil 3D to allow users to use Both, Point Names without assigning a Point number.

Well, "yes" and "no". C3D always assigns a Point Number, even when you are using Point Names. There is no way to automatically get it to parse numbers as Point Numbers, and alphanumeric strings as Point Names.

But you can pull the file into Excel, and duplicate the column that has your Point Numbers in it. Now edit one of the columns, and change all the alphanumeric strings to an unused point number. Then create a Point File format that imports your new data, with the extra column. In other words, instead of using a PNEZD, you would now have a file that has "Point Number, Point Name, Northing, Easting, Elev, Desc", and every point would have both a Point Number and Point Name.

There's actually a big thread on Autodesk's DGs right now about Point Names and how they are such a pain in C3D:
