Hi, i have a file in a geodatabase that in its at attribute table has the columns: OBJECTID, SHAPE, E, N, Z. I know that it should be a TIN file but i don't have it like that in my workspace, but as points. I have no idea from geodatabases, and why it is in that form there? It has been maden form LiDAR data that is for sure.

Any idea how can i convert it to TIN?

Use the Create TIN tool on those points.

If they're not points already, make them into points first, using the coordinates.

looks like the table that already has coordinates, hence the Shape field.  any more info? or is that all there is, just the table

I tried it and worked fine. Thank you very much . I have one more question, would it be more correct if i had tranformed them firstly in .LAS through txt2las and then from LAS to TIN?

You started with a point feature. So the approach outlined by Darren is perfect.

Actual LAS files are a different thing altogether. If you have a collection of LAS files, create a lasd dataset using Catalog and go from there.
