Rhino WIP has an all new ArrayCrv command. What is ArrayCrv? ArrayCrv has been updated to allow you to quickly and easily repeat objects along any curve, making it simple to create patterns, details, and design features that follow a path. Whether you’re adding decorative elements, or laying out re…

Yeah for sure, I do think we could eventually introduce some sort of list of sizes on the curve. I don’t see this happening for v9’s new ArrayCrv revamp but could certainly happen going forward. I’ve made a ticket so that we don’t forget about the request. ArrayCrv add list of sizes/coun…

The Array Curve Plus plugin (from Jarek? I think?) allows for per-item scaling as well as start/end scaling. Works very well, would love to see the same functionality in the new Array Curve tool. [Screenshot 2026-03-24 163428]

I’ve been waiting for this for years!!! Thank you!!!

When using history, editing the curve works only 1x:

Would you then use a “Round” such as Floor/Ceiling/Neutral (similar to GH) to select which value to use from the list?

Late to this discussion, tried to read everything to catch up but I apologize if I’ve missed an explanation here. I’m trying to use ArrayCrv for the legacy behavior and can’t figure it out… Do I need more coffee or is this actually difficult? ArrayCrv Simple.3dm (57.7 KB) [image]

The initial alignment is by objects bounding center and world orientation, not the objects location in the world. ArrayCrvOld still supports the older method. Best practice is to create array objects around the origin for maximum positioning options and control during layout. [1449]

Fair enough. I see what you’re doing. For a moment I thought maybe I could set a CPlane aligned to my object and then use that to orient but that’s not an option either. I see why this is more powerful. I’ll keep ArrayCrvOld in my pocket until I get over the muscle memory of building my objects dire…

It definitely is a shift from the “from here” alignment of the old tool. That method worked but got limited quickly and didn’t do a good job of supporting a list of blocks that you might want to sit and noodle with and a few other weird alignment scenarios. However, we don’t have any plans of removi…
