Hi everyone!
When presenting drawings of electrical systems, HVAC systems, internet systems, and fire protection systems, we usually use the architectural drawing as an Xref. If we keep the layer colors the same as in the architectural drawing, it becomes difficult to view, so we often change all Xref layer colors to one color.
