[C#] Scale problem <<

I wanna create List<Surface> something like that (Bottom).

What's the problem of my script ?

protected override void SolveInstance(IGH_DataAccess DA)
{
Brep brep = null;
double factor = double.MaxValue;

if (!DA.GetData(0, ref brep))
return;
if (!DA.GetData(1, ref factor))
return;

List<Surface> srfs = new List<Surface>();

Interval inter = new Interval(0, 1);

for(Int32 i = 0; i <brep.Surfaces.Count ; i++)
{
brep.Surfaces[i].SetDomain(0, inter);
brep.Surfaces[i].SetDomain(1, inter);

Point3d center = Point3d.Unset;

center = brep.Surfaces[i].PointAt(0.5, 0.5);

brep.Surfaces[i].Transform(Transform.Scale(center, factor));

srfs.Add(brep.Surfaces[i]);
}

DA.SetDataList(0, srfs);
}

Thanks in advance :D

Surface types are untrimmed. If you want to keep trims, use brep and brep face instead of surface.

Hi Hannes ~

You mean brep or brep face data type has trimmed information ?

Thanks :D

A Brep is a topological type collection of objects, it consists of the following data (not an exhaustive list):

Faces (each face is a surface with trim and loop and edge information)
Edges (the 3D curves around all faces)
Loops (lists of edges that form closed loops)
Vertices (all the sharp kinks in all loops)
UV curves (representations of trims in each face's UV space)
Meshes (optional, but each face can have several type of mesh associated with it)
Topological data. Each face knows which trims surround it. Each edge knows which faces border it. Each vertex knows which curves meet there etc. etc.
