The Rhino WIP adds new Grasshopper Hatch components to its set of tools. You can now create, edit and save Hatch patterns. Rhino WIP also includes a new HatchPattern command in Rhino that can also work to create new hatch patterns. Why This Feature? Previously, creating custom hatch patterns in Rh…

Hi @wim , Thanks. For now, this workaround fixed the problem: packing the properties, merging into a single stream, and sorting before previewing. It kind of forces me to build cleaner scripts, so that’s not too bad :slightly_smiling_face: [image]

It is clear that the Grasshopper preview may not be using the same rules as Rhino for draw order. This is mainly because it is simply a preview and lacks a lot of the information a normal object would that has been added to Rhino. We have that YT to look at. Here is a consistent way to “preview” a…

Thanks Scott, this is actually pretty fast. I’m just wondering if there’s a way to automatically purge the geometry when the script is disabled or closed, similar to the behaviour in RiR components, where you need to Release Elements, which initially confused the hell out of me …

By eliminating the result output in the content cache it will even be faster. There are a few ways to release the objects. Using bake action may also work in your case. Although, do you mean to have it dynamic for a while, then release it later at a certain point? Or are there multiple different op…

Thanks Scott, to clarify, I’m after an ephemeral mode: keep the objects in the Rhino doc only while the GH definition is running, and automatically delete them when the definition is disabled or the GH document is closed (basically GH preview behaviour, but as real doc objects so vector print respec…

This might be related to RH-76822 . I also came across this old thread with an interesting comment from @DavidRutten . Back then, Ctrl+F / Ctrl+B on the components used to affect draw order, but that no longer seems to work.

There are ways to make the Content Cache delete objects with a toggle switch. But, the automatic hook on close or hide needed in this case is difficult. There are event watchers for closing a document etc…. but that seems extreme. Setting the model Read-only would do it.

Hi, I’m coming back with an issue regarding dot patterns. I created one using the new Grasshopper component. However, when I try to use it, I can’t set a different color for the background. The background and the pattern elements always remain the same color. Best, Pip, [Capture d’écran 2025-0…

Thanks for reporting RH-89637 Pip. I’m seeing this as well.

Thank you for following up. I also noticed in the above file that line hatches can be exploded, but dot patterns cannot. Is this intentional? It might be useful to explode them sometimes.
