become dxf 3d into a solid

[Mix88]

Good morning I am facing a bigger problem than I know and therefore I ask for the help of the forum, I must import in an illuminotechnical calculation program a valley detected and realized in 3d autocad with the isoipsa level at 1m. the program that I use only accept solids and therefore I have to transform the floor of the valley into solid. I meshato with a software downloaded from the internet topocal the section of valley that interested me of which I simplified the isoipsa at the levels of 5m, then I realized the mesh to triangles. now I have a nice 3d floor of the valley in dxf. how do I turn it into a solid? If I was unclear I apologize but I am a little confused. Thank you.

version of the cad?
from 2011 (if not erro) you can convert mesh to smooth surfaces and thicken to get a solid.
is easy the file will increase considerably weight

not wrong; the problem is that most likely mix88 does not have a mesh but a tint, that is so many 3dfaces approach each other

...2006.

you did not mention the assertion of tristan on the nature of your model (3dface), assuming that you are right you should operate "by hand":

- draws from the top of a triangle a vertical line (to the bottom) longer to the height of the solid you want to get
- select all 3dfaces and then estrudi with option tRaettoria (the line previously designed)
- select and combine all extruded solids from the 3dfaces
- draw the solid resulting from the share of the plan that interests you


p.s.: it goes more to explain it than to do it
p.p.s.: you cannot use the method indicated by joseph as you have a version that does not allow you
p.p.p.s.: You may also use the m2sa lisp of arklisp, but the procedure I described is faster as you should give an enter for every 3dface of the model.

Yes, we understood, what asked gp. is whether your surface consists of many separate triangles (3d faces) or if it is a single mesh.

the surface consists of many separate triangles, created on the polylines that sent me from the topographic program. for the realization of the triangles I used topocal but now I realize that extruding them do not all go in the same direction. I created the solid but I can't orient the faces of the triangles so that the extrusion goes in the same direction.

dear mix88, have you read well the last post of gp.?
follow exactly what is written and you will see that everything is resolved
