[GRASS-user] Why does v.split convert 3D vector to 2D?

2010-03-07 Thread Dwight Needels
I have a 3D vector [test_3D] created using v.drape, confirmed as 3D with v.info. I used v.split to split the polyline at the vertices: v.split input=test_3D output=test_3D_split vertices=2 The resulting vector [test_3D_split] is a 2D vector (i.e. it lost the z geometry data according to v.in
