Hi @cole.fritz, Check these out and see if they help: > [@Creating solids from volumetric surfaces via dynamo](https://forum.dynamobim.com/t/creating-solids-from-volumetric-surfaces-via-dynamo/62807): > > Hello guys, i’m trying to create some solids from my volume surfaces inside dynamo, but i’ve encountered a couple problems: First, when we create it directly from the civil3D UI, the prompt is somewhat different from the normal solid extraction: [image] as we can see, the normal parameters that define the solid (depth, fixed elevation and at surface) can’t be modified. So, the nodes i got to create surface from the civil3D toolkit all come with one of these parameters. Any ideas how should I … > [@Batch create volumetric surfaces](https://forum.dynamobim.com/t/batch-create-volumetric-surfaces/62632): > > Hello guys, what i’m trying to achieve rn is exactly the topic name, batch creating volumetric surfaces between my already existing TINsurfaces. I’ve searched the forum and the closest I got from it was this post: [Getting surface information from C3D using Python - #5 by jduran](https://forum.dynamobim.com/t/getting-surface-information-from-c3d-using-python/44258/5) but i can’t seen to do this operation for multiple inputs! any help around this issue? thanks in advance --- _[View the full topic](https://forum.dynamobim.com/t/breaking-tin-surface-into-solids-by-bound-regions/63677)._
