How to create points with the help of sample lines?

How can i create/export points using sample lines.

Hi @mughaladeel9, what would be the output you are looking for?

If you only need the Sample Line endpoints (vertices), with VisualLISP, you can drill down to the Location property for each vertex. It would be easy enough to create a COGO Point or an AutoCAD Point at that location. This code creates AutoCAD Point entities at Sample line vertices. Select a Sample Line, the code will place points for all sample lines in the group.

(defun c:go ( / smpl smpgp smplns ctr cnt vtcs vcnt vctr vtx loc)
(vl-load-com)

(setq smpl (vlax-ename->vla-object (car (entsel "\nSelect a Sample Line: "))))
(setq smpgp (vlax-get smpl 'Parent))
(setq smplns (vlax-get smpgp 'SampleLines))
(setq ctr 0
	  cnt (vlax-get smplns 'Count))
	  
	  (while (< ctr cnt)
			  (setq smpl (vlax-invoke smplns 'Item ctr))
			  (setq vtcs (vlax-get smpl 'Vertices)
					vcnt (vlax-get vtcs 'Count)
					vctr 0)
					
					(while (< vctr vcnt)
							(setq vtx (vlax-invoke-method vtcs 'Item vctr))
							(setq loc (vlax-get vtx 'Location))
							(setq vctr (1+ vctr))
							
							(vl-cmdf "Point" loc)
							)
							
			(setq ctr (1+ ctr))
			)
			(princ)
			)

I'm looking for the points at specific interval and offset with single click.

What do cross section reports offer?

[TerryDotson · Accepted solution]

If you were to consider third party add-ons, DotSoft's C3DTools will process an alignment, collecting points (optionally places CogoPoints) along the sample lines.  Exports station, offset, northing, easting and surface elevation at specified intervals (like -10,0,10) or all points where the sample line intersects the triangles of the surface.

[ecfernandez]

You can create the points wherever you need them and then use the "Station Offset to Points" report to get the information

Set the corridor to the sample line increment and write cog point from corridor >> export
