General solution for equidistant pattern on breps?

I find surprisingly few topics on this when I search, so maybe I’m using the wrong words… what I mean is that the distance between the points/repetitions on the brep should be equal when measured along the surfaces…

Not sure if this is an idealized video, but the Grasshopper clone in Siemens NX seems to handle patterns across breps in a pretty generalized way:

Is there something similar for Grasshopper in Rhino?

99% of all examples I ever see in Grasshopper is with a single surface, and 0% of my CAD models use single surfaces… :slight_smile:

this interface is very like grasshopper

Hi @zhuangjia777,

It is a common paradigm in visual programming tools.

I’m going to request a trial of the Algorithmic Modeling feature in Siemens NX to see if they really solved it or not, because I find it very weird that nobody even seems to want to go near this in Grasshopper.

Well, just got word about the cost of that Grasshopper-like add-on in NX and even though NX is expensive, the cost for that add-on alone was eye wateringly crazy expensive… so I’m not even going to bother with a trial of it to find out if they really have a general solution or not. :sweat_smile:

Have in mind that NX (but CATIA as well) are used for entirely different purposes than R/GH … by entirely different cliantele … doing entirely different things (like an Airbus or a Boeing or a Mercedes or a Ducati).

Kinda like comparing prices for a Golf GTI (the best affortable “all purpose” sportish car) VS a 911 GT2 (the best track weapon if you can handle 700 bhp).

Oh, believe me, I know. We have about 10 NX seats and a few in Catia still. In fact, I made that exact comparision in another thread here recently. :laughing:

And with that in mind, I still made that comment, so… damn, Grasshopper is cheap.

I also have 3 NX seats and 4 CATIA ones (plus 15 AECOsim) … and you know what? They are really cheap IF you take into account what you can do (and IF you can sell the product). That said I’m in the AEC/BIM market sector (Final level Studies and the likes) … and … well … R/GH can’t actually play ball on that game.
