Simplifying layer structure by merging

[spb (Steven Burzinski)]

After reading There is a block definition on layer X, delete it before deleting layer , I want to bring to others’ attention, MergeLayer, a method that exists in RhinoScript but doesn’t appear to be in the UI. This method has been quite valuable to me for simplifying layer structures, those either created by me or by others (typically imported from another CAD system), with or without blocks.

I just wrote a more robust version in RhinoPython and wanted to share:
xLayer_merge.py (5.1 KB)
(rhinoscriptsyntax doesn’t contain MergeLayer, but it easy to replicate its behavior.)

A MergeLayer command has been requested a few of times in this forum, but I didn’t find an issue for it in YouTrack.

Merge Layers

Hi Pascal and all ones looking for a merge layer that works with blocks I finally managed to script a “full” merge layers from both or your scripts Script Process Choose Source layers that will be merged Choose a unique target layer All Source Layers are merged to target All Source Layers in blocs and nested blocks are merged to target Prompt “Yes No” to Purge empty layers I would LOVE to add an option for a complete layer deletion, even in nested blocks… Enjoy (and help if possible) Bes…

I’ll check yours soon

Thanks
