Help!! Vector Issues
Sorry guys! I've just ran into another problem with Vector2pt.I am trying to set up a behavior between two points using the Vector2pt component, however as seen in the picture below, the point…Continue

Circle CNR aligned to curved surface
13 Replies
Hi all,Just a quick question: Is it possible to align circles made by the CNR component onto a curved surface such that it flushed with the surface curvature. much like tiling a curved surface with…Continue

Diagrid Edge and Extruding in direction of surface normal
Hi guys,I am doing a case study on the Carpenter Centre Puppet Theatre done by Harvard GSD students. I'm not very familiar with grasshopper and rhino nor am I proficient in scripting,however I have…Continue

Hi guys,I'm an architecture student who is very new to grasshopper, I would like to create an equilateral triangle grid on an angled/folded/curved surface that i can list points out of to generate…Continue

June-Hao Hou replied to Adeline Leng's discussion Circle CNR aligned to curved surface"Your example shows that three mid-points moving inward/outward in equal distance and reside on a circle centered on the triangle's center of mass -- that's because they are on an equilateral triangle. For non-eqilateral triangles, just…"

Sorry guys! I've just ran into another problem with Vector2pt.I am trying to set up a behavior between two points using the Vector2pt component, however as seen in the picture below, the point circled in blue is unable to move towards the target point circled in green. Instead it has moved away from the target point, hence the resultant point circled in red. I would like the point circled in blue to move towards the target point circled in green properly and I suspect it has something to do…See More
Adeline Leng replied to Adeline Leng's discussion Circle CNR aligned to curved surface"Hi June,
Sorry for the late reply! It is difficult to describe what i want to achieve in terms of my surface module hence I will upload a few other files to illustrate what I wanted to do :)"
Adeline Leng replied to Adeline Leng's discussion Circle CNR aligned to curved surface"Thanks Evert! sorry for the slow reply, I was studying for my exams yesterday! I will try out the definition now! :)"
June-Hao Hou replied to Adeline Leng's discussion Circle CNR aligned to curved surface"Just saw your file and tried to figure out what you intend to have. Here comes a straight way of getting circles on the triangle panels (not onto the surface) -- see the attachment. Once you increase the number of divisions you get smaller…"
Evert Amador replied to Adeline Leng's discussion Circle CNR aligned to curved surface"Hi Adeline,
Does this help?
Cheers
Evert"

pyrit replied to Adeline Leng's discussion Circle CNR aligned to curved surface"theres already a discussion on this, have a look

pyrit replied to Adeline Leng's discussion Circle CNR aligned to curved surface"since im myself no pro, i cant help you really much...
look in the def i attached.
you see that if you dont have same tiling it wont function because inner circles of the triangles dont have the same tangent points.
so you have to look out for a…"
Adeline Leng replied to Adeline Leng's discussion Circle CNR aligned to curved surface"sorry for the double post! but i have uploaded the files on the thread. These updated ghx file highlights the CNR circle in the definition that needs to go onto the curved surface
Thanks once again :)"
Adeline Leng replied to Adeline Leng's discussion Circle CNR aligned to curved surface"Hi pyrit!
Thanks for your reply! I have attached the relevant files in my reply to June above. The ghx file is done in 0.70055 and the 3ds is done in SR8. Please take a look if you can :)
I wish to control the radii of the circles by attractor…"
Adeline Leng replied to Adeline Leng's discussion Circle CNR aligned to curved surface"Thanks for your quick reply! :)
I've just tried the Evaluate Surface component. However, it turns the CNR circles into funny spheres. I wonder what did I do wrong? :(
I even tried using a guide circle done by Circle 3pts to extract the plane…"
pyrit replied to Adeline Leng's discussion Circle CNR aligned to curved surface"i think you may first look out how to tile your surface. because if you want to maintain same sizes, i assume that also your tiling has to be made out of equal parts.
but then you are limited in getting the overall shape, because with bigger…"
June-Hao Hou replied to Adeline Leng's discussion Circle CNR aligned to curved surface"Yes, as long as you can get the normal vector of a point on the surface -- try Evaluate Surface component for this matter."
