# 005 : Triangle Pattern Tower - Al Bahar Towers

[@khs2110]

원기둥 심? internal edge 없애는 과정이 번거로운데 연습을 위한 과정인가요? 혹시 다른 방법은 없을까요?

Is there no speech explanation ?

Thank you

[@Touchhhhhhhh]

Your tutorials are great and really fascinating! I really enjoy watching each one of it. BTW I have question about "-1" Indices you connect to "Cull Index" Command in 11:30, What does that do to the Index that different from other numbers? Thanks in advance :)

[@Touchhhhhhhh]

I assumed that It has to do with finding center of each panels, I tried finding center by using "Area" command to generates center point of each panels, but once I wired them to other command, It fails.

[@RhinoGrasshopper]

You can read the list in reverse order of index. The reverse order starts at -1.

Hi, Thanks for the tutorials, I started to learn now. I have the latest version of Rhino and therefore GrassHopper. Right at the beginning, I don't find the command used: "Triangle Panels B", I believe it is from an earlier version. Is there any alternative? Thanks

16:30 에서 MOVE에서 빼서 SHIFT LIST로 넣는 건 어떤 버튼을 누르면서 하신걸까요? Ctrl , Alt 눌러봐도 안되네요..ㅠㅠ

[@RhinoGrasshopper]

ctrl + shift 키를 동시에 누르시면 됩니다.

Hello! Do you have a vídeo making the same building but using a program called Julia?

[@jimnoelarchitect_6688]

정말 감사합니다. 호주에서 건축석사과정인데, 이게 과제라서 힘드네요. 근데 21분쯤 가다가 point extrude하니깐 너무 느려지는데 어떻게 할지 모르겠네요

[@RhinoGrasshopper]

실행속도가 느려지는 대부분의 이유는 Data Matching의 문제입니다. 영상속의 컴퍼넌트에서 "Flatten"과 "Graft"의 체크여부를 잘 확인해서 다시한번 해보시기 바랍니다.

[@shaileesolanki5444]

the expression command shows error and other wise also the panels dont get selected in a straight line. Please help me

[@RhinoGrasshopper]

Without your definition, I can't know your question exactly.
