Glyph script that automatically generates half-OH topology between two connectors that form a closed loop.

Operation

The main purpose of this script is to help expidite the manual generation of structured topology in the area between two connectors that form a closed loop. It can be thought of as a half-OH topology, as it produces a topology geometrically similar to the upper (or lower) half of an OH grid.

To run, simply highlight two connectors or one unstructured domain with an edge defined by two connectors and execute the script (for versions >= 17.2R2), or execute the script and then select the connectors/domain. The topology will be automatically created. There is a dimension in the operation that is subject to contraints, but can be chosen automatically based on an optimal value. However, if you would like control over this value, there is a flag in the script on line 39 that allows you to use a GUI.

On line 37, the input(AutoDim) variable should be used with caution. This prompts the script to automatically adjust the dimension of some connectors that are not dimensionally consistent. While logic is included to try and prevent any changes resulting in unbalanced domains, this can sometimes fail, resulting in undesired behavior.
