Bake Objects into separate layers

Grasshopper
1

Hi,

I have a loft and have split this into 3mm layers, I need to take each of these layers, make them into 2D then bake the result into separate layers. I have worked out how to find the surface I need and make this into 2d but now I need to figure out how to do this all in one go with say 40 slices. The output 2D parts should be grouped and put into separate layers - or at least not all staked on top of each other around the same centre point

I have attached the photo of my diagram - The pink group is the one currently finding the layer set by the left slider (currently set to 0) - so the top layer - then finding the second largest surface then making this into 2D - I need to find a way of doing this for all 40 layers in one command - later editions may have 400+ layers

Thanks in Advance!!!

Hi,

Thanks for this - I have tried this but it just bakes each layer to a new layer (good first step)- is there a way to incorporate this into my make 2D function (Pink Group)

Thanks
Callum

Oh, so baking is not the issue, just basic GH skills? I actually agree with you, bake to layer should be easy.

This bakes each branch of the Make2D ā€˜Visible curvesā€™ to a separate layer but doesnā€™t try to move them around from where you put them. Is that the real point of this thread?

My code doesnā€™t bake groups.

This spreads out the Make2D branches in the X direction. What do you want?

Cricketsā€¦ Iā€™m sorry, did I step on your toe? This thread title ā€˜Bake Objects into separate layersā€™ threw me off, I didnā€™t realize immediately that your question is (apparently?) more about layout, AKA ā€œnestingā€, before baking than baking to layers?

Is @Petras_Vestartas in the house?

Or you could spend $1K for RhinoNest:

Hi,

Iā€™ve got this working now quite comfortably and with a few more parameters - I think the way Iā€™m making the layers by doing a linear array of the rectangles, then extruding and then doing a boolean difference between them and the loft is a clunky way of doing it.

Can anyone point me to a quicker way of doing this? This single boolean operation takes up around 90% of the computing time. Iā€™m now trying to do an animation of the lamp growing and shrinking and I need to make the compute time as little as possible.

I think a something like a wire-cut would be quicker but then how would I delete the unwanted layers?

Thanks
Callum

Also Joseph Iā€™m now using deep nest you should check it out: https://deepnest.io/
