Breaking out components

My question is simple, but can not seem to find the solution.  See attached image.  I have a swept surface, sub divided the surface into points along its section.  For my next operation I would like…Continue

You could flatten the list and use list item to select the point you need. -Boris

Breaking out components

My question is simple, but can not seem to find the solution.  See attached image.  I have a swept surface, sub divided the surface into points along its section.  For my next operation I would like to use just one of the points.  How can I break the points out to select just one of them??  Any comments are appreciated,  Thanks!See More

Have you tried using the Eval Component (Curve>Analysis>Eval) this allows you to obtain a point on a curves length it will accept either a length factor i.e. 0-1 like the output of the graph mapper or as a specific length along the curve just…

Ah ha! Thanks for the clarification. Still working on it and not getting too far. Maybe I don't quite understand the component. Going to see if I can find something in the manual. thanks for the input.

There are two Mass Addition Components One for Vectors and One for Numbers have a look under Scalar>Utilities in version 0.6 or Maths Tab in v0.7

Thanks David, I've tried the Mass Addition and not sure what going on. The output understand that there are 75 vectors (correct), but wants to place each vector equally 1 units apart... Maybe I am missing something. Am I making this difficult…

Hi Greg, you could try using Mass Addition to add all the segment lengths together. The Partial Result output of Mass Addition should then give you lengths along the curve for every point. However, this approach does not guarantee that the whole…

Dividing of Curves into Unequal Lengths (using graphmapper)

I am looking for advise on how to divide a curve into unequal segments using the graphmapper. Attached is my definition file and a screen shot. What I would like to do is this: Using the graphmapper, take the output values and apply them as length segments on a curve.In the attached screen shot, you can see the length values in the notepad. Am I taking a wrong path here??? Unfortunately, this is a small portion of a definition I am working on. I would like to use the graphmapper to generate my…See More

Thanks Giulio, this has been very helpful. Nice definition. I have about 5 days experience with grasshopper so this insight is very appreciated. How about that definition I sent!?! I bet it was entertaining. Again, thank you. Greg

Hi Greg, I'm sending an example of how you could begin the same design with Grasshopper Trees (a more lightweight way). It's not finished yet, but it will give you an idea of how to start. I've also converted all breps into meshes…

Well, you could draw the curves as size "1" and then scaling with these current radii? Or, alternatively, adjust the scaling values to the length of the curve, or its planar area? This logic could be kept all same and just become the…

Hi Guilo, Very informative solution. Unfortunately, I've tried a similar approach that you suggested. Here's the tricky part about this problem. I believe I need to use a type of scaling factor to size the rings instead of using a range of…
