Thank You So much,Tig. It works !
This is the idea to revise a model from architect by storing data at the first time. And later use to recheck data for tagging panels , and take the panel out in order that the facade engineer can do the life size panels to do mapping back on sub-dividing panels.
The method I do :
The subdividing faces are in the "Layer0".
The patterns are in the Layer-"Patterns".
So , they are not mix together in the same layer.
For the shortage time to "delete coplanar edges or patterns" , I have to select edges by degrees and use your code to delete edges because the group edge and original edges are overlap that I have to delete original edges.So , it doesn't affect to bring tagging panels out , and I can recheck the patterned data to do retag panels.
For the store patterned data , maybe it comprise of 3 functions :
1.Make edge group
2.Select Coplanar edges by degrees
3.Delete Coplanar edges selection
