In ICM add AutoCAD layers to usertext1 on import
When importing from autocad layer mapping can be used to create a model layout for things like 2D Mesh zones but all created objects are null. I have written an SQL to apply parameters to all null mesh zones and roughness zones and import each layer individually. If the autocad layer was written to usertext1 I could import all at once with a saved layer mapping and then enter all parameters by selecting usertext1

This could be useful in more instances than just importing for 2D Mesh zones. AutoCAD .dwg or .dxf files usually have little information other than the object type (line, polyline, point, area, circle, etc) and name of the layer the object is on to help distinguish objects. AutoCAD uses named layers to distinguish (and often color) objects of a common type, like ICM and InfoAsset Manager use tables for nodes, conduits, etc.
So all the lines representing pipes might be one layer, circles or blocks on another layer might represent manholes or valves, etc.
