# THREE-DIMENSIONAL GEOMETRIC SOLVER

This section describes another software component of the C3D Solver
module -- the three-dimensional geometric solver. The three-dimensional
geometric solver is applied for geometric modeling when you need to
arrange 3D-dimensional objects as a diagram of mutual relations and make
them subject to geometric constraints and dimensions. You may need this
for the following tasks:

-   Merging solid body parts into assemblies;

-   Kinematic analysis, including an inverse kinematic task;

-   Solid body assembly animation;

-   Modeling 3D wireframes.

In combination with the collision detection component (see Chapter
[Collisions detection of
bodies](../../RESULTS/COLLISIONS_DETECTION_OF_BODIES/Collision_Detection_of_Bodies_en.md))
the geometric solver helps CAD users assess the motion boundaries of
mechanism parts.
