The MicroStationAPI provides a C++ API for MicroStation developers wanting to create custom applications for MicroStation® from Bentley Systems.

MicroStation is a 3D computer-aided-design (CAD) tool and platform. Developers often want to write applications that manipulate 3D objects. Third-party computational geometry libraries may provide assistance.

Third-Party Computational Geometry Libraries

There is a number of C++ third-party libraries that deal with computation geometry and related topics. Use one of these in your native-code application DLL built using the MicroStationAPI.


Eigen Silly Professor

EIGEN is a C++ template library for linear algebra: matrices, vectors, numerical solvers, and related algorithms.

The Computational Geometry Algorithms Library


The Computational Geometry Algorithms Library (CGAL).

Geometric Tools


The Matrix Template Library

MTL Logo

The Matrix Template Library (MTL).


The Boost.Geometry library provides geometric algorithms, primitives and spatial index.

Boost QVM

Boost quaternions, vectors and matrices (QVM) is a generic library for working with quaternions, vectors and matrices of static size with the emphasis on 2, 3 and 4-dimensional operations needed in graphics, video games and simulation applications.
