"Hi Angel, would it be possible to upload the image in a higher resolution. I am trying to learn from your script but im finding it difficult to recognize certain components. Thanks a lot."

"really interesting to see your feedback here on the accuracy of kangaroo for real loads. I've found it great for early stage concept work too."

"Nice! I've been using kangaroo this year in the bar position and pattern design stage for a big stadium project at my school. I've used SAP2000 for the final calculations. The results and process was really nice because kangaroo give us…"

"other victims of invalid surfaces from split srf, I just ran into the same problem, Spliting planar surfaces. I found that when I got the Brep edges, it had interior edges. When I baked out the edges It seems the one edge of the surface was not…"

"Hi David, hi Carlo, i ran into a case that sounds similar and attached an isolated reproduceable bug. Choosing one specific edge of my Srf, I will constantly get an "invalid" result from the SrfSplit components. All others work fine. I…"

not printing objects that are behind a surface ?

Hi, Probably not the best place to post this question. But I have a quite large facade which i divided in different pieces. Each panel received a text dot and text tag through grasshopper. However when I print a certain view text tags from another facade also get printed. Which gives a quite unclear picture. Is there an advanced setting in Rhino to compensate for this ? Without "hiding" every text tag which is in the way manually. Or is there a grasshopper way to do this ? thanks in advance. See More

"I'm not ignoring, I don't have any new information yet. This is clearly one of our bugs. Can you post the files I need to replicate this? (and, does it also happen in Rhino5?) -- David Rutten david@mcneel.com Poprad, Slovakia"

David Rutten replied to Carlo Rousseeuw's discussion Invalid Surface ?

"Hi Carlo, there's all kinds of things that could make a surface (especially a brep) invalid. If you feed the invalid object into the [Null] component, it will tell you why the shape is invalid. It's probably going to be a bit…"

Invalid Surface ?

Hey there, I'm having a an issue with the concept invalid surfaces. I'm using a script and i need to cut up an exisiting rhino surface ( not planar) into different smaller pieces using certain parameters. However using Surface Split component I sometimes keep getting and "invalid surface". And I cannot cut up this "invalid surface". Any pointers on how to get a normal surface, or even what this error means ? Thanks in advance. See More

"Hi Carlo. I'm very intersted in your work, I also find very useful your method to define stiffness values. Did you make the kinematic test? Is Kangoroo approximation acceptable? Thanks Andrea "
