l := sketch.set.region.nodes(sp<,ib><,i>)

Get the list of 2D vectors that correspond to the positions of the nodes of an element with local index i within a block with ID ib. The index i can vary from 1 to sketch.set.region.element.num. If the element index is not provided, the function returns all nodes within the block. If the block ID is not provided, the function returns all nodes within the set sp.

Returns:

l - list of node positions

Arguments:

sp - sketch set pointer

ib - block ID

i - element number with 1 \(\le\) i \(\le\) sketch.set.region.element.num.
