Terrain Mesh

[Mokiloke]

I am not very ACAD literate but I have been given a site mesh that looks like a mesh but is in fact a whole lot of lines making up triangles.

 

Is there any way to convert this to a surface or mesh without doing it triangle by triangle as there would be thousands of triangles

[STRAT]

if it's infact just lines and not faces then im afraid you'll have to re-mesh it from skratch

[graphix]

If they are a bunch of lines that form closed triangles the region tool will turn the individual triangles into renderable faces.

 

nevermind....the ucs needs to be II with each new "face".

Hmm tried region and selection all 27000 objects and tried region but it has said that 0 regions created. Could not figure out what to do with the UCS though.

[graphix]

in order to do what I was talking about you would have to make the UCS parallel to EACH triangle and do them one at a time............. that would be a big negative unless you would like to spend the rest of eternity doing it.

 

 

BUT I had a thought while I was at work today making a terrain for a job:

If you have VIZ you may try importing that file into viz and using the create terrain tool. Then export it back out as a DWG file.

 

best of luck,

You could try the edgesurf command.

 

I have created polylines, based on topography, one closed poly for each gradient, then edgesurf each closed poly. It's been like 2 years, I use VIZ Terrian modifier from ADT polylines now.

 

It may help
