### BReps

A BRep, or ** Boundary Representation**, is the data type used to hold generic geometry. If, for example, we use the

*node to create a box, the output is in the form of a BRep:*

**Box**The types of topological components contained in a BRep are * Vertex*,

*,*

**Edge***,*

**Wire***,*

**Face***,*

**Shell***,*

**Solid***,*

**CompSolid***.*

**Compound**We can use the node * Brep Components* node to extract the different components, by selecting the corresponding type in the

**T**attribute of the

*node.*

**Brep Components**#### Vertex

A zero-dimensional element representing points in geometry.

#### Edge

One-dimensional shape corresponding to a line or a curve and bounded by a vertex at each extremity.

#### Wire

Sequence of edges connected by vertices.

#### Face

Part of a surface bounded by a closed wire(s).

#### Shell

Set of faces connected by edges.

#### Solid

Part of 3D space bounded by Shells.

#### CompSolid

Set of solids connected by their faces.

#### Compound

Set of any other shapes described above.
