Hi everyone,
as a beginner. i'm trying to learn how to use the Hexablock Module in salome.
but there is always an error,when i try to associate the vertex of the block to the geomety.
by vertex association i can only use the first algorithm-- by coordinate. when i choose the other algorithm like by reference or by an edge and a parameter etc., the error occurs: TCollection_DataMap::Find.

does anyone knows what is this problem? or how can i fix it?

thx
