"Do you mean you want to keep three levels of Branches? If so then currently you have {3;0;0} (N=16) {3;1;0} (N=16) {3;2;0} (N=16) and would like to have {3;0;0} (N=1) {3;0;1} (N=1) {3;0;2} (N=1) .... {3;2;15} (N=1) Using the Path Mapper {A;B;C}(i)…"

"There is an offset on Surface component which is more reliable but uses more processing time."

Danny Boyes replied to stoltm's discussion Offset of simple curve fails
"OK. Some of this is related to the RhinoCommon offset routine using user supplied inputs at the time of running eg direction. There have been several work arounds to over come this problem such as Offsetting both sides and calculating the new curve…"

Danny Boyes replied to Ali Nayeri's discussion How to create and modify a persistent list
"I think the way to overcome this is to find the central axis of the whole column and use that as the point to calculate spurs from and rotation. In the image above the left hand average point is closer to undamaged side and therefore creating the…"

Danny Boyes replied to Scott Davidson's discussion Welcome to the Grasshopper to Revit Forum in the group GH>>Revit
"Hi Muthahar, not wishing to seem pedantic, but native GH is more about repetition than recursion. My favorite quote "To understand recursion, you must first understand recursion". In GH there is no mechanism that allows resulting data…"

"Here's a definition that includes a perimeter sorting algorithm using a circle and CPs to get the points aligned better. "

Danny Boyes replied to Ruth's discussion Paneling a surface with open-closed components
"This is certainly possible. If you haven't used the Image sampler before the I would suggest this approach. 1) insert a Picture Frame of your chosen image into Rhino. 2) Reference Surface from Rhino. 3) Reparameterise the Referenced…"

Danny Boyes replied to paul piciorul's discussion data tree
"I can only suggest that the subsurfaces are not in the order you thought. You can order them first with a 2D sorting algorithm first before grouping them into rows or columns. 2d sorting FAQ"

Danny Boyes replied to Meagan Wood's discussion Z Axis Planes/Drawing Curves
"When you say "on the Z Axis" I take it you mean the closed curves drawn on the YZ construction Plane in the image above. If so then you can draw them in the "Right Viewport" (opposite to left). You can either make use of the…"

"Are you restricted to any number of points to define the surfaces? can they be trimmed surfaces?"

Danny Boyes replied to Matthew Roberts's discussion The "INT" Component
"the inputs a and b can be either connected to a dynamic source or be internalised for the lower and upper bounds of the surface that you are subdividing. they are probably 0 and 1"
