In this display, different parts of the simulation results are color-coded for ease of identification, as shown below.
If you open a project file (.tivus) generated with Simulation Utility 2018.1 or earlier, the structure type displays just four element types, as follows:
0 – Build Plate
1 – Part
2 – Support Structure
3 – Failed Support Structure
But if you rerun the simulation, you will see the full range of structure types.
