Sylvie574	Posted - 07/14/2025 : 11:17:30 PM 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,
