Origin Ver. and Service Release (Select Help-->About Origin): Origin 2024
Operating System:Win 11

I’m trying to draw a 3D region shaped like a slightly curved trapezoidal box. The boundaries are defined by multiple points fitted into planes. I can plot each plane individually, but I don’t know how to combine them into a closed volume.

An example of the desired result
（The number of planes I want to draw is not as many as the examples）

I’d really appreciate any advice on how to achieve this.

Thank you for your time and help!

Best regards,

YimingChen

You can use the 3D Convex Hull app to create a plot from boundary points.

I attached a project for your reference as well
