pub fn edge_uses(
model: &Model,
shape: &Shape,
) -> OgeomResult<FastMap<TShapeId, usize>>Expand description
How many times each edge node is walked by the faces of shape, every
placed occurrence of it together.
Whether an edge is free or shared is a question about one occurrence:
two placements of one face share every node and are two faces, each
walking its own edges. placed_edge_uses answers it.
