Hi Felipe,

Here's one way of doing it. It does require the use of the Unweave component available at http://www.grasshopper3d.com/group/milkbox/forum/topics/tree-sloth

Well .. with regard the specific images provided[1A,1B]:  For each surface and each node calculate the bisector Vector (sum of unitized vectors [either the direction per side or the tangent, case curve edges], unitize it, multiply it by the desired double [distance from node] and then your point is:

pointAtBisector = nodePt + (bisectorUnitized * distance).

Starting with Ethan's code... filter by distance between points and surfaces:
