@subsubsection occt_modalg_7_2 Offsetperform function.
The offsetperform functon uses 2 algorithms presented by 2 methods of the *BRepOffset_MakeOffset* class:
* MakeThickSolid: makes a thick solid from the initial one.
* MakeOffsetShape: makes offset of the initial shape.
Let’s consider the *MakeOffsetShape* method.
*MakeOffsetShape* method.
*MakeOffsetShape* can use 2 algorithms:
* BuildOffsetByArc: simply makes offset faces and then creates arcs between them.
* BuildOffsetByInter: constructs offset using intersections.
The *BuildOffsetByArc* algorithm is quite simple while *BuildOffsetByInter* is more complex.
Let’s consider *BuildOffsetByInter* in detail.
*BuildOffsetByInter* calls *MakeOffsetFaces* and passes to it a map of faces that should be offset.

To make an offset, *MakeOffsetFaces* uses the *BRepOffset_Offset* class.
