Apparent intersection between two objects

[Costinbos77]

That's good advice Hipper013. But if you do not have AutoCAD Civil 3D, what can you do?

 

I started working on this program in January 2014.

So far, I have managed to create the 3D TIN , do sections , to draw contours and calculate volumes.

And what is more interesting, I can constrain TIN by 3D objects.

 

And still not finished the year.

 

To intersect an object 3DMESH with a linear object, you must first put z = 0 for all TIN and then reset the coordinates.

 

(setq lisCooTIN (vla-Get-Coordinates myTinV)  )

(function "put z = 0 for all TIN")
. . .
(while (setq lisCooI (vla-IntersectWith myTinV objLin acExtendNone))

. . .
)

(vla-Put-Coordinates myTinV lisCooTIN )
