INCONS_FACE Warning when trying to cut geometry in Dynamo for Civil 3D

Hello everyone, I would like to pre-emptively thank you all for the answers.

I’m currently working on a railway project and need to cut the dormants geometry from the ballast but I keep getting the INCONS_FACE warning when trying to apply the Solid.DifferenAll Node and I don’t really know why.

For context: I did import the solid geometry from the ballast but, for reasons of memory usage, opted for generating the dormant geometry inside Dynamo and translated the geometry with the coordinate system of the dormants in the project.

I have 2 solids from the ballast wich I joined using Solid.ByUnion Node, and approximately 1,2k dormants, wich I also used the same node to transform it into a single solid, both have generated one single Solid just as I expected, so no problem until now.

The problem arises when I try to apply the Solid.DifferenceAll or the Solid.Difference to those geometrys. For sciences sake I’ve tried a bunch of combinations with and without the join geometry nodes, but, without luck, none have given any different results.

If anyone has by any chance any information, solution or lead I would be very happy!

Thanks all!
