All enteties layer 0 To layer per color

Lippens Infra

Recommended Posts



I have a lot of drawings comming from an export f.e. Tekla stuctures. 

Those drawings have no layer structure, only thing to categorize entities are the colors.

Is it possible to create layers per color and get the entities in that layer?


Thanks in advance
