Hello everyone,

Is it possible to have the extrusion of smaller triangles from exactly the surface it cutting the bigger triangles …? Thanks in advance

Hello @Kumar_Kapadia,

I have the solution; this is not an elegant solution, but this is how you can achieve it. (DYN attached.)

Thanks,

DYN is here…Triangulation_Updated.dyn (83.4 KB)

That was a Daily Build of Dynamo available on Dynamobuilds.com.

BTW, those builds can only be installed if you have Revit 2015 or higher installed on your machine.

If you want I can create the same graph for you on DynamoStudio 1.1.0

Thanks,

Ritesh

I use dynamo studio stand alone student version anyway i have revit 2016 but the dynamo version for that is also same that is 1.1.0…anyway will appreciate if u make the same graph for 1.1.0… thx

@Kumar_Kapadia The file below should explain the process of creating a cutting tool aligned to a surface.

In case you aren’t able to open the attached file, below is the code. The rest you should be able to rebuild from the image

```
//Icosahedron
p=(1+Math.Sqrt(5))/2;
a=Point.ByCoordinates({0,0,0,0,p,-p,-p,p,1,-1,-1,1},{1,-1,-1,1,0,0,0,0,p,p,-p,-p},{p,p,-p,-p,1,1,-1,-1,0,0,0,0});
b={{a[0],a[8],a[9]},{a[0],a[9],a[5]},{a[0],a[5],a[1]},{a[0],a[1],a[4]},{a[0],a[4],a[8]},
{a[1],a[5],a[10]},{a[1],a[10],a[11]},{a[1],a[11],a[4]},{a[2],a[3],a[7]},{a[2],a[7],a[11]},
{a[2],a[11],a[10]},{a[2],a[10],a[6]},{a[2],a[6],a[3]},{a[3],a[6],a[9]},{a[3],a[9],a[8]},
{a[3],a[8],a[7]},{a[4],a[11],a[7]},{a[4],a[7],a[8]},{a[5],a[9],a[6]},{a[5],a[6],a[10]}};
srf1=Surface.ByPerimeterPoints(b);
```

Wow …Thank you so much Sir
