I'm not quite sure that I understand what you did, but I tried the Listlength-Series-Item-ReTrim, but it gave me the same results as connecting my lofted cylinder and the tubes the other way around in the boolean dif component.
Maybe I'm describing it the wrong way, don't usually use Rhino, but was intrigued by the Grasshopper plugin. In Moi3d this is what I would expect the Boolead dif to do: http://www.pusselasken.se/screencaptures/boolean_dif_moi.gif But when I use the boolean dif in grasshopper I get this result (the result is baked and pasted into Moi3d): http://www.pusselasken.se/screencaptures/boolean_dif.gif The first version shown is when the lofted cylinder is connected to the A-input of the boolean dif component. The second when it's connected to B. /Lars On 3 Dec, 15:34, "[EMAIL PROTECTED]" <[EMAIL PROTECTED]> wrote: > Hi Lars, > > I had the same problem some days ago, with planarSrf though.
