Hi guys. Sorry this is probably a super easy thing. But I've literally started with houdini today and I'm struggling to find up to date and good information in many places :p

My ultimate goal is to create a tile generator for a dungeoneering game in unity.

At this point ive managed to build a wall via a sweep.it follows a curve and that great but I would really like to have a “ floor generator” which I was thinking I could just randomly generate a bunch of copies of grids using the parameters and some randomness to get odd and intersting floor shapes.
Then link that too my wall generator and it would follow a curve round the floor.
However you have likely already spotted my short sightedness.
Currently when I link my wall generator to my floor generator the wall build across all edges. Not just round the outside leaving it not so useable :p
How can I pull a curve from pull the outside of my floor geometry and have it ignore all the edges running through it.

I'm currently not at my machine. But if you need any more info or a project file let me know.

Thanks in advanced !

Any chance you coupld post a HIP file showing an example of something like what you've got and describe what you'd like in that context? It's a bit hard to visualize it without a HIP file.

My wild guess would be to use a Group Create SOP to select unshared edges and a Dissolve SOP set to dissolve non-selected with that group specified, but it's hard to know if that makes any sense without an example.

The divide node has an option to remove shared edges which essentially creates an outline.

Hello ! thank you so much !

i had an idea it would be to do with grouping i just couldn't figure it out xD i got it to work and its fantastic thank you ! my resolution was to layout the grid in any shape i wish, fuse it. group it by unshared edge and dissolve ungrouped ! this is exactly what i needed ! thank you very much for your help i look forward to getting back into the flow of my project
