Ezigrade 4.1.30

Bug fix in linear programming. Under certain circumstances  the variable grading could lead to "infeasible solution" even though a solution is possible. Variable grading with constraints on one axis only has been speeded up.

Ezicad 4.1.29

When using the triangle based grading we have improved the smoothing option. It now knows how to fix up the smoothed surface around section links. When running the grading we have the following dialog presented.

Tick on the "smoothing between sections" option and add in a value distance to use. Make it big enough to include any imperfections around the link.
