A thorough analysis of these three types of imported beams can be found in the Importing My First MiTek Job Walkthrough. The three icons represent the three different scenarios that can happen when a MiTek member is imported. The first is that the beam is adequate and ready to be exported to StruCalc, this is the green icon.
The second is that the beam imported correctly but there are warnings associated with the beam, this is the yellow icon.
