Select all curves from a layer in Rhino?

[Ryan_Saks]

I have a set of curves drawn in rhino (all on one layer) and I have this set of curves linked in grasshopper to a curve node. I am continuously adding to this set of curves, so I have to continue to “set multiple curves” in grasshopper to add my newly drawn curves to the set. I have everything on the same layer in rhino.

Is there a way to have grasshopper select my set from everything on that layer so I don’t have to keep going back to grasshopper and adding to my curves set?

Geometry Pipeline - very old component.

Geometry Pipeline

thanks so much! That worked. Is there a way for it to select a sublayer though?

I assume the standard layer naming convention applies? Let me check…

I thought double colons (“::”) between layer name and sublayer name would work but I guess not. I don’t have more time right now, search the forum?

GH Geometry Pipeline not collecting data from sublayers

Problem Solved: I was using a legacy version of the component at first, then the current version without adapting my use. Cheers, Gavin Rhino 7 Version 7 SR25, Grasshopper 1…7 Hi Thanks for your help. I have been using Geometry Pipeline quite a bit recently but suddenly I find that I cannot use it to collect data from sublayers any more. I know there are ways to filter layers but to my knowledge I have not applied any such filtering. Not sure why this is happening or what I may have done to…

Apparently not How STUPID Please, someone tell me it’s not so?
Not even in R8.

Grasshopper Geometry Pipeline nested layer wish

Yeah it was pretty trivial. The full layer path string is now compared against the layer filter, so that assuming a file with three nested layers: Default Default::SubLayer1 Default::SubLayer1::SubLayer2 you can filter: Default (the first layer only) Default* (all layers) Default::* (sublayers only) *SubLayer2 (third sublayer only) the problem is that this changes the behaviour. Previously, SubLayer2 would have selected the third l…

@DavidRutten

Ideally I’d like to make it smarter than this, but that will have to wait until GH2.

don’t despair, make sure the full layer name is written between asterisk with double colons between each sublayer name. see attached

This component lets you filter objects by layer or sub-layer.

[Tom_Newsom]

Yeah sublayer selection was working last time I used it, a few months ago

The nice things about this is Pipeline is limited on what is can reference this will allow to reference a bunch of other stuff.

I can see your brep but can’t see my curves. Struggled for a LONG TIME… before finally succeeding - thank you. But still fail with Untitled.3dm

I don’t think the leading and trailing asterisks are needed.

As to why my Untitled.3dm failed, it’s because the curves are on the ‘Default’ layer instead of the ‘crvs’ sublayer. I swear, I went over my changes very carefully, many times.

[BTH]

i just removed the asterisks and it does work, weird… i clearly remember making scripts a couple years ago where asterisks were required otherwise the layer wasn’t selected.

Try like this in geometry pipeline component

MainLayer::SubLayer1::SubLayer2
