I am wanting to do some analysis in Abaqus on the unit cell of a lattice. I designed the geometry in Grasshopper and want to export as a STEP file to Abaqus. First I created lines that represent the lattice geometry. I then applied Multipipe to make the model solid. I then split the BRep using a box that represented the volume I want to keep. I extracted the index 0 item from the list (the Brep I wanted to keep) and applied Cap holes to make it solid.
However, pipes that have multiple open faces (Circled in yellow) aren’t capped. Is there an easy way I can cap these holes?
The output I have to work with is a single Brep with ~1000 edges so it is difficult to identify the edges of those open pipes from which I could maybe create a surface.
Any suggestions would be very appreciated.
I have attached the grasshopper file. The Purple and light blue groupings are just geometry creation. The pink group is my output and maybe the orange group is of interest where I trim the Multipipe component to what I want. I am using Rhino 7.
