er =,i)

Get the next edge connected to the node with local index i within the source edge e. This can be used to iterate through all edges connected to a node using the function.


er - next edge pointer


e - source edge pointer

i - node index with 1 \(\le\) i \(\le\) 2

Usage Example

The following example illustrates how can be used to iterate through all edges attached to a node, counting the number of edges.

    global test21 = geom.edge.node.pos(pnt,2)
    global test22 = geom.edge.pos(pnt)
    ; Test node to edge loop
    global test23 = 0
    local node_pnt = geom.node.find(setpnt,1)
    local edge_pnt = geom.node.start.edge(node_pnt)
    local node_ind = geom.node.start.index(node_pnt)
    loop while edge_pnt # null
