jkunz07 Posted May 14, 2014 Share Posted May 14, 2014 hard to tell from your question as: ("../something" , something else) is just two arguments. One example might be: centroid("../null1", D_X) in which case your getting the x component of the centroid of the geometry in "../null1" This is commonly used in an add sop to fill in each component of the created point's position like: centroid("../null1", D_X) centroid("../null1", D_Y) centroid("../null1", D_Z) So you will have a point which represents the centroid of whatever geometry is fed into "../null" Maybe look at the sidefx expression docs or use exhelp in the textport for more info Quote Link to comment Share on other sites More sharing options...
