Solver

The addon utilizes the solver from solvespace which takes a set of entities with an initial position and a set of constraints which describe geometric relationships between entities. When the solver runs it will try to adjust entity locations to satisfy the constraints.

Solver Failure

It's common that the solver fails to find a solution to satisfy all constraints. There are multiple reasons why the solver might fail. Whenever this happens the active sketch will be marked in the sidebar. It will have one of the following states:

Okay
Inconsistent
Didnt Converge
Too Many Unknowns
Unknown Failure
