I find it!))
May be usefull to anybody.
It's work:
--------------
Modeler::MeshBody* mb;
VERT *vrt;
int ivcount;
mb = element_memo.morphBody;
if (mb->IsWireBody())
{
ivcount = mb->GetVertexCount();
for (int i = 0; i < ivcount; i++)
{
vrt = (VERT*)&mb->GetConstVertex(i);
vrt->x = 1;
}
}
// And then do change memo to apply changes on Morph element.
