Conversion from BREP to IPT is not supported yet :(

A Brep file is a 3D model stored in the boundary representation (also known as B-rep). The Brep format is a part of Open CASCADE Technology (OCCT).

The Brep structure is made up of two major components:

• topological components such as faces, vertices, and edges;
• links between components such as surfaces, points, and curves.

It comprises three-dimensional data such as vertices, edges, wires, faces, shells, solids, compounds, edge and face triangulations, polylines on triangulations, space location, and orientation.

An IPT file extension is used for Autodesk Inventor objects.

Autodesk Inventor is a CAD application that engineers and product designers use to construct prototypes of mechanical products. These prototypes, referred to as assemblies, consist of several individual parts joined together. Each Inventor part is saved in an IPT file.

Inventor users can import IPT parts from outside the program or create their IPT parts using the Inventor's part design tools. Typically, users begin by creating a 2D drawing of a part before transforming that drawing into a 3D model. Thus, an IPT file may contain either a 2D or 3D object. Files in IPT format can be opened using Autodesk Inventor 2017, Autodesk Inventor View 2017, Autodesk Fusion 360, and SpaceClaim Engineer.
