Hi wing-bend,

Thanks for the image, but images typically don't provide a lot of information. A C4D file does provide more data, and can be attached here up to 1MB directly. (Sorry about the long instruction…) If larger, for security reasons, please upload uncompressed to either WeTransfer, Google, Dropbox, Apple, or Adobe cloud services. The URL is fully pasted here, no HTML wrapper.

Here is what I was imagining from your image:
CV4_2026_drs_26_MOcw_01.c4d

I have unchecked the End-Cap in the Thicken to showcase the change in a better way. Deactivate the Connect Object to see the effect. It is perhaps the closest to my understand what you are looking for.

Let me know how that works.

All the best
