After following this discussion, I’ve made a script that you can use to create a block definition layer structure when creating a block.
And another to organize blocks onto layers with their block name
@pascal @Helvetosaur what do you think?
see the code
import rhinoscriptsyntax as rs
import Rhino
def organizedBlock():
"""
create a block from selection and add it to a layer with the block's name
nested under layer Block_Definitions
tested in Rhino 6.14
www.studiogijs.nl
"""
#get objects to create block from
objs = rs.GetObjects("select objects to creat block from")
if not objs: return
base_point = rs.GetPoint("block base point")
if not base_point: return
def checkName():
block_name = rs.GetString("enter block name")
if block_name =='' or block_name==None:
print "block name can't be empty"
return checkName()
#check if layer Block_Definitions exist, else create it
if not rs.IsLayer("Block_Definitions"): rs.AddLayer("Block_Definitions")
#check if layer with block name exists, else create it
if not rs.IsLayer("Block_Definitions::"+block_name):
block_layer = rs.AddLayer(block_name, parent = "Block_Definitions")
else:
print "block definition with this name already exists"
return checkName()
return block_layer, block_name
block_layer, block_name = checkName()
#create the block
block = rs.AddBlock(objs, base_point, block_name, True)
if not block:
return
temp_layer = rs.CurrentLayer()
rs.CurrentLayer(block_layer)
rs.InsertBlock(block, base_point)
#restore to previous layer
rs.CurrentLayer(temp_layer)
if __name__ == '__main__':
organizedBlock()
