3D polylines survey to model

Good evening everyone,

 

I admit I have been looking for a solution for days, but I couldn't find anything so far - I hope some may have a solution for me on this, so thanks in advance!

 

I basically have the survey of an highway, composed by 3D polylines, and available as .dwg file.

What I am trying to do is to have a solid/mesh/model in 3D.

With qGIS I am able to extract punctual cross sections with the elevation profile, but I'd prefer to have the whole infrastructure in 3D to have a solid/mesh to reproduce the topography of the whole thing.

 

Do you know if there is a possible solution to do this?

I don't know if I explained well what I am trying to do, eventually just ask me for more info

 

Thanks again,

Have a nice evening

Hi Nicolò,

 

Although this not possible in plain AutoCAD, you can try this way:

 

1/ Use attached put_points.lsp to create points on the vertices of the 3D polylines

2/ Use attached TRIANGULATE__Elpanov.lsp to create 3DFaces from points, created in step #1

3/ Convert 3D faces into mesh as described >>>>HERE<<<<
