Exporting polyline nodes?

[scott_hicks]

Is it possible to extract the coordinates (x, y, z) of polyline nodes to
an ascii file?

Thanks,
Scott

Here is the work arround I got:

Open the dwg file
Export the polylines to a GML file using the MAPEXPORT command
Open the GML file in EXCEL as an XML list, This might generate an error - let Excel fix it by selecting yes.
Delete the unneeded columns in Excel keeping the coordinate string for each polyline (my column is ns2:coordinates8)
Select the column and change the format to General (to get rid of the #########)
Export this as a TXT file and you can do pretty much what ever you need to with it.

I added some object data to the export that was my GIS_ID and I was set.

I use a LISP routine called "ptexport" that directly exports polyline nodes
to a comma-delimited text file. The LISP routine came from
http://www.dotsoft.com; click on "Free Stuff" on their home page. The text
file contains x,y,z coordinates.

What the export does NOT provide is any point ID. The export list starts
with the first point of the polyline and proceeds to the end, so you can
number the points (e.g., on a printed list or in Excel), count them on the
polyline and label them manually.

Something to be aware of when exporting polyline nodes: nodes can sometimes inadvertently get "stacked" -- that is, multiple node points with the same coordinates.

When the nodes are exported, there will be duplicate values in the text file. This will throw off hand numbering on the drawn polyline (because the "stacking" is not visible on the drawing).

Use the command line MAPCLEAN or Express tools > Modify > Delete duplicate objects to get rid of these "stacks" and then "ptexport" again. Sometimes I have to run both these cleanup routines more than once to "fully clean" a polyline. Not sure why that is.

The right command is _MAPEXPORT, sir.

Ouch, sorry for that. And Thank you!

There is also a short way, you can use the list command, copy all, then paste it into a txt file and delete all the words that are not important, then saved in csv format.

Dear Friends,

i want to extract X,Y,Z from polyline but easiest. i just select the line and used LI Command for list, it's asking 30 times to enter and even not able to find full data easily, as well as after copying from list, have to delet extra txt and have to arrange separately xyz., as you've given the lisp locaiton at : http://www.dotsoft.com/freestuff.htm i am not able to find that LISP file for xyz txt file etc.

please can anyone send me quickly to Abuhasan3k@gmail.com

Many Thanks,

Problem to get the data from 3D Polylines/Points/Blocks which should be in original xyz form. how to extract data from all these types?

Answer is to uplaod a Lisp file and use as mentioned in website and you can play around for other options.

Hi,

see attached file .rar.

Save your file in dxf format.

This small saftware export all the entity in xyz coordiantes in a txt file.

Try, and let me now
