Parametric 2d/3d CAD

whitequark 000bf71a50 Add a setting that permits a group to include redundant constraints. ... This setting is generally useful, but it especially shines when assembling, since the "same orientation" and "parallel" constraints remove three and two rotational degrees of freedom, which makes them impossible to use with 3d "point on line" constraint that removes two spatial and two rotational degrees of freedom. The setting is not enabled for all imported groups by default because it exhibits some edge case failures. For example: * draw two line segments sharing a point, * constrain lengths of line segments, * constrain line segments perpendicular, * constrain line segments to a 90° angle. This is a truly degenerate case and so it is not considered very important. However, we can fix this later by using Eigen::SparseQR.		2016-10-25 13:48:49 +00:00
