Importing an ASCII File?

[bill]

I have an excel spreadsheet from a surveyor=containing coordinates, piint numbers and an elevation for additional spot shots. I converted it to a .txt file and want to import these points into my existing topo file (dwg).

It seems I need to create a ".crd" file. I keep getting asked to possibly dump these points into a .crd file.

Am I on the right track?

There must be a way to import spot elevations?

Which exact Autodesk program are you using? You opted to post in a forum that literally has nothing to do with your topic in any way shape or form.

Bill,
"It seems I need to create a ".crd" file. I keep getting asked to possibly dump these points into a .crd file."
Need more information on that. Maybe a screen shot? Are you using Vanilla AutoCAD or a vertical like Civil 3D? Can you post your point file?

If you are creative, you can take the content in Excel, create a block definition with attributes and create a script file that will play in AutoCAD and produce the results.

Otherwise, post your XLS file and someone will create a .DWG you can insert into your topo and assuming they are on the same coordinate system, it should overlay.  Also, a .CRD is most likely a Carlson Software Coordinate file which is binary and not going to help you at all without an application to handle it.

If your work will involve frequent interaction with survey work then Vanilla AutoCAD may not be a suitable software. AutoCAD Civil3D (or perhaps Map3D) is what you’ll need. The csv and txt formats are only some of the file types understood by C3D/M3D. 

Being able to read and insert points from an ASCII file is just one part of creating a drawing. You’ll still be faced with ‘interpreting’ the coordinates used by the surveyor. For example, the coordinates sent to you can be in feet, meters or Lat/Long degrees. If coordinates are geographic lat/longs then you, or the program you use, will need to convert them to feet (or meters) so they can be inserted accurately into your drawing. Common formats for lat/longs are decimal degrees and deg-min-sec (DMS).

If you are tasked to go beyond point insertion, e.g. create a surface, cut a surface profile or perform volumetric computations, then Vanilla Cad won’t suffice. You most def need C3D.
