Old question about sdivide and lists

does any one know how to extract the points of a divide surface component into groups of 4 (the 4 corners of the surface) or how to convert the following list into groups of 4 and not 2 items??

i think its a big drawback for the sdivide component to classify the points into groups of 2 instead of 4.

thanks!!!

David has previously explained this changed behavior of the divide component; it allows one to keep track of the points of trimmed surfaces, something previously impossible. To solve the problem, you simply have to "flatten" the lowest level of tree structure, which is achieved with the path mapper. In the case you've shown above, simply feed the output from the simplify component into a path mapper, and double click the path mapper to set a mapping from {A;B} to {A}. This will give you a set of lists with four corner points in each one.
