Hello everyone,
I’m re-posting this thread as it’s likely to get more responses on this sub-forum (and because this message board seems to lack the ability to relocate your own threads).
I’ve been modeling road networks, and so far I’ve used to it manually, creating roads with the Sweep-modifier, and connecting them to pre-modeled intersection and transition blocks. I think a dedicated plugin might be able to automate most of the process.
The way I see it, it could be a modifier working something like this:
- Assume that the entire road network is built within a single editable spline object
- Look for the coincident vertices in intersecting paths
- Break any coincident vertices, and move them apart to make room for a pre-modeled intersection block
- Insert the intersection block, and align the previously moved road vertices to the matching edges of the intersection block
Obviously the paths should contain the road type information in some way. In my opinion, the "Shape ID" setting should work fine for this. A certain shape ID would then be linked to a certain road cross-section shape in the settings.
The user would manually determine the proper intersection/transition blocks to be used for different (or identical) road types. After filling up the required details, the modifier/plugin could automatically do its job.
The above is of course a simplified description, and there are some additional details that would be involved.
