Activate the strength factors toolbar – after Map3D BEM analysis.
This toolbar is meant to provide quick access to the failure mode plots.

Notes:
The strength factors toolbar can only be activated after the model building - CAD Stage
Map3D Analysis Stages
Any of these components can be added to the contour toolbar if desired
