Hi,
I extruded the model from Figure 1 and the problem in Figure 2 appeared. I did in the interface of Plaxis LE, what happened?
From the screenshot it is not entirely clear what causes the extrusion to not work in your case. Probably two surfaces/regions overlapping each other. To assist you further please submit a service request with the model. Then, one of our support engineers can help you in detail: https://apps.bentley.com/srmanager/ProductSupport
