How to create a 3D polyhedron knowing the vertices?

[RGX124]

Hi,

I would like to create a 3D Polyhedron in CAE or with a Python script.
I know all the coordinates of the vertices.
Extrusion is not possible.
Is there a way to create the edges, then to add faces and finally create a cell?
If possible please let me know.

Thanks

For difficult shapes I usually start out with a general shape, like a cube for instance, and then cut out the parts I don't need using cut/extrude or whatever. Imagine it like sculpting the shape from a block.

I usually just make the parts in a CAD package. For a simple shape like this I would check your favorite programming language and see if someone has already done it possibly exporting to IGS. After that I would write a program that meshed the outside of the part with triangles similar to an STL but in Abaqus format and import it as an orphan mesh. I hope this helps.

I know already this method which is good for one or two polyhedra, or the same polyhedron that is repeated.
Are there general methods to build a partition of random polyhedra within a box?
I have the coordinates of the vertices.

Thanx
