Drew an line on a layer with layer color set to red - Fail.
Drew a line on a layer and changed the lines color property to red using the code you helped me with earlier - Success.
Did the same with a dimensions.
Dim on Layer with layer color set to red - failed.
Dim on Layer with overridden dimclrt, dimclre, dimclrd to red - failed.
We have one layer that uses color bylayer RED. I can deal with that.
