Hi,

if I use \_explodeblock than the internal layer structure of the block is reset to the current layer. If I use \_explode than it works. Maybe an option could be added to the \_explodeblock command to select the final layer method.

Ciao,  
Micha

PS: Same reported for R6. (no reply there)

Hi Micha - the workaround for the moment is this -

[ExplodeBlocksToLayers.rhp](https://global.discourse-cdn.com/mcneel/uploads/default/original/3X/7/c/7c4922af4c4daa24a6261719c8c33abed360742c.rhp) (14.5 KB)

Drag and drop that plug-in onto Rhino to add `ExplodeBlocksToLayers` command. You probably want the non-default option for how to treat layers. Indeed it does seem like this a job for `ExplodeBlock`.

Oh, I feel like we talked about in the past. It’s not easy to keep the little workaround in mind. 🙂

Thank you very much for your kind help. Could you set it on the bug tracker please? It should be a standard function of R6 explodesblock.

Hi Micha - I added a comment to the bug track item to, hopefully, give it a boost…
