convert a DTM in a .DWG format in a .TIN format in Arcgis

Hi everyone,

I need the help of the GIS community for a question related to TIN. I have a DTM created with Covadis. My topo points are connected with triangle 3D face.

Now, I would like to obtain exactly the same DTM but in a .TIN format in Arcgis (I would like to avoid to re-create an entire TIN in Arcgis as the work was already done in Covadis). I'm pretty sure there are easy ways to do it, but as I'm a GIS-beginner, I don't really know how to do it...^^

Here are all the software I have: Autocad Map 3D 2011, Covadis 11, Arcgis 10.1 and Autocad Cicil 3D 2017

Thank's to all of you for your help!!

the only direct tin import can be found here LandXML To TIN—Help | ArcGIS for Desktop and cad tools are found here CAD to Geodatabase—Help | ArcGIS for Desktop if the TIN is properly constructed, then you should be able to recreate it from a Delaunay triangulation from the input points which apparently you don't want to do Fundamentals of TIN triangulation in ArcGIS—Help | ArcGIS for Desktop
