Exporting .xyz points file

[unearthed]

I have a need for an .xyz points file for manipulation in another software. While VW allows export of early dxf formats, there's no option for export of 3D points aka vertices.

 

Currently I'm using https://www.guthcad.com/dxf2xyz.htm but it adds quite a few steps (and ime requires a very early-format .dxf), and it'd save time to avoid it.

 

.xyz points file format looks like this:

81525.081217,21129.437724,490.905487 - for X Y & Z coordinates

Make a worksheet of the points and export a CSV file from there.

Thanks Pat, I just realised I forgot to say the points are currently the vertices of a group of 3D polygons which are contour lines.

AEC:Survey Input:3D Polys to 3D Loci command.

 

Make sure you put them in a new class so it is easy to isolate them and to use as a criteria for making the worksheet.

Thanks Pat!, If I ever knew of that command I'd forgotten  it. It makes that very painless.

Do what Pat sez. It gives points only on the contours, as you requested. Probably lots of them.  If the selected spacing misses some sharper contourq curves, add a few extra loci by hand. 
 

A similar approach is to create, in a new class or layer, an array, over entire site, of 3d Loci on layer plane, via the Edit>duplicate array command. Choose xy spacing values to optimize the count. Send to surface. Call the xyz values into a worksheet and export csv.

None may land exactly on the contours, but will be evenly distributed over the site. If that’s any advantage.

Gridding vs arraying

Thanks Benson Shaw, I was wondering how I could use Edit>duplicate array, and a nice simple route to thin points. In this case my client supplied data is amazing but my outputs don't need that level of definition.
