SecFrames does not work on multiple items

Hi,

The function Sec Frames does not work the way I want it to. Can anybody help? See below picture and the attached .gs file.

The frames should appear on both the open Brep as the trimmed surface in the first branch. But it does only on the trimmed surface in below example.

Note that each branch at the input of the sec-frames-module belongs to each other. So the planes of the first branch are for the first branch of Breps.

Thanks in advance, Bas

Hi David,

This might be a problem for you to look at.

Cheers,

Bas

I did, and I typed up half a response before I realised I wasn't answering the question you asked.

It's true that the section component will operate on one shape/plane pair at a time. You therefore need to make sure all your shapes are in separate lists, because you want to slice each one with multiple planes.

It's a pretty tricky data management problem though. I can't see a clean solution.

Hi David,

Thanks for your time and help.

I tried the option with all shapes in a separate list by grafting the tree, but then I run into other problems like in this discussion I posted:

Matt Gaydon came with a good solution to list the frames belonging to each other, but this solution does not work with multiple (main)branches. I played around with the function _TreeItem, but without good results. Indeed a tricky data management problem. I hope someone can give a hint for a working solution.

Cheers,

Bas
