TIN export to ASCII

MichaelaRepkova — Thu, 21 Oct 2010 04:23:29 GMT

hi everybody,

can anybody help me, how can I export the TIN to an ascii file which contains the information about vertices coordinates, and about which vertices form the triangular cells?

for example:
221.2973 175.5181 0 (node 1)
228.6197 193.1957 0 (node 2)
246.2973 200.5181 0 (node 3)
263.9750 193.1957 0 (node 4)
271.2973 175.5181 0 (node 5)
263.9750 157.8404 0 (node 6)

(1 3 2)
(2 4 2)
(5 6 1)
(1 3 4)

its mean that the first triangle is obtained connecting node 1 with node 3, node 3 with node 2, node 2 with node1.

thanks

1. 'Tin Node' tool to extract nodes from TIN into a 3D Point feature class.
2. 'Feature Class Z to ASCII' tool

hi, i did it, and result is,
for TIN node

    0 -332994.12500000000 -1181715.99991174000 1260.155029296875
    1 -331454.12500000000 -1183615.99991174000 970.069519042969
    2 -331214.12500000000 -1181595.99991174000 1389.363647460938
    3 -333294.12500000000 -1182575.99991174000 1556.582763671875
    4 -333314.12500000000 -1182575.99991174000 1546.826538085938

    But I still dont know which nodes belong to one triangle.

and for TIN to triangle:

    0
    -331214.12500000000 -1181595.99991174000 1389.363647460938

    -331214.12500000000 -1181595.99991174000 1389.363647460938
    END

    Here i know nodes of triangle but i dont know ID of nodes.. so i still dont know which nodes belong to triangle. I would like to have result like in my first thread..
