Relier is a software that enable to link points for the drafting of network. It is available for Bricscad®, Autocad®, Ares/Corelcad®, et 4mcad®, in french and english version.

From a set of points to be linked (points, circles, or blocks) and a polygonale boarder (2d or 3d polyline) surounding the dots , the software can compute four kind of networks, and the associated minimum spanning trees.

List of the functionalities

Relier has eight main commands for drawing the following networks:

The generation of the network can be constraint inside concave polygons.

For every kind of network, one can link a set of point entities, the centers of a set of circles, and the insertion points relative to a set of blocks; by simple lines or by polylines formed of two consecutive arcs (randomized a little bit). The entites to be linked can also been filtered by their belonging to a specific layer.

Limitations:

Performances

The performances of execution (magnitude of time on a 1.6Ghz processor) are for normal spanning trees in the case of a convex boarder of about 300 secondes for 1000 dots, and same time but only for 100 dots in cas of the rectilinear spanning tree. in the case of concave boarders and normal spanning trees, the execution time can be much more long with a presumably factor of 100, depending on the complexity of the boarder and the number of points to be linked.
