Isn't there a way to add a prefix to a point in Carlson? I have a range of points that I only want to add the letter U in front of the ex. pt. number.
Renumber points in the coordinate file utilities does not seem to do it. I seem to remember that another routine would do what I want, just can't find which routine.
Make sure your coordinate file format is alpha numeric. Export your points to a txt file.
In a text editor, edit the point numbers to have the U. You will need to create a new crd file. Then re-import your points.
Thanks.
I was thinking there was a routine in Carlson that would do it.
I was going to use the same method you suggested if I couldn't do it through Carlson.
You can renumber a range of points in Carlson, but I'm not sure if you can use that routine to add an alpha prefix.
Not sure what Carlson program you are using, but you may find what your looking for under the points menu, then coordinate file utilities, then point description.
Add prefix or suffix.

The third party software "Toolpac" has that feature (among many others). You can add prefixes or suffixes to any annotation.
I can think of a way but it'd involve two point renumbering steps:
1. Make sure your CRD file is AlphaNumeric (Points -- Coordinate File Utilities -- Convert Format will tell you what it is and allow you to change it as needed).
2. Renumber your points with a large value (e.g. 1000000) to get a unique, searchable string into the point number. If your largest point number was 999, its new number would be 1000999 and would make the "1000" portion unique across your point list.
3. Choose Edit -- Text -- Find and Replace Text and replace 1000 (the unique portion from above) and replace it with "U" (or what ever you desire for the new point number prefix) and make sure the "Search Blocks" toggle is enabled.
4. As needed, issue the Coordinate File Utilities and Update CRD from DWG as desired.
I'll check with programming to see if there is an easier solution and will report back if one exists.

I should have stated that my existing points are already alphanumeric. When I try your method it leaves the alpha character in place and adds the 1000 to the numeral.
G240 becomes G1000240
It's not really a big problem, just would be nice to be able to add another letter in front without editing each point individually. I will probably just live with it for this job.
It works the way I described above. I'm running Carlson 2010 with Autocad 2010. It just won't work unless you create a new crd file set at alpha numeric.
That actually simplifies things a bit:
1. From the Points menu, click Edit Points
2. Click Search -- Replace
3. Replace "G" with "GU" and set the Point# field as the field to search through.

Thanks, Keith.
I know your way would work, I was thinking there was a routine in place that would do it quicker, but I guess I was wrong.
Thanks, Ladd.
I actually have several different alpha characters, not just "G". Each field crew is assigned a letter, and several different crews have been at this particular project.
I know I can edit them that way, was just thinking there was a routine that would do it all at once.
Blew that one. Never used alpha numeric coordinate files. I thought you wanted to change the description. JRL
