extract points from dtm with autocad

[Duix]

Good evening to all,

I have a dxf file that represents the digital model of the soil made of various polylines that also represent the elevation.
I would need to extract x,y,z coordinates from the model and then import them into another software.

How could I do that?

Does anyone have any suggestions or suggestions to give me?

thank you in advance for the answer.

greetings to all

polylinee3d or 3dfaces?

 

[Duix]

should be 3d polylines...as they represent the orography of the soil...thank you for the answer.. Do you have any suggestions to give me? ?

Explode all the polylines, then with the command you excreted extract the x, y and z coordinates of beginning and end of the lines in a db access, then make a query of deletion duplicated and carry out in csv.

thanks tristan for the answer....I made a test with a single polylinea....in the table that I go to export I find for every coordination the following items: start x, end x, start y, end y,deltax, deltay, start z, end z, etc.

so in reality what I get are segments not points?

All I need to build a grid to import into a software for the simulation of wind farms.
possibly there would be any alternative, being you a civil 3d user?

Thank you very much

Why? Forgive me but... start x, y, z and end x, y, z are not two points? :36_1_12:

If you have civil3d you don't need to do anything...just create a surface with dxf objects and the game is made

Good morning Tristan,

I tried with your suggestions...but by eliminating duplicates I don't go to delete points? ...in any case how much obtained continues not to be accepted by the simulation software.


I have the following situation:

point 1) start x1 start y1 start z1 end x1 end y1 end z1
point 2) start x2 start y2 start z2 end x2 end y2 end z2

with end x1 that coincides with start x2....eliminando fine x1 do not lose information?

I have the following situation:
point 1) start x1 start y1 start z1 end x1 end y1 end z1
point 2) start x2 start y2 start z2 end x2 end y2 end z2

Forgive me, but this is the geometry of elementary schools. a point is formed by a coordinate terna and not from "start x1 start y1 start z1 end x1 end y1 end z1".
"start x1 start y1 start z1 end x1 end y1 end z1" are 2 points

with end x1 that coincides with start x2....eliminando fine x1 do not lose information?

if end x1 and start x2 coincide you have a duplicate information. What do you do with two identical data?
