Geometry idealization > Creating midsurfaces before meshing
Define a midsurface with the Offset method
From the Insert menu, select Model Preparation→Midsurface→Offset.
In the Offset Midsurface dialog box, click Target Body and select the body.
Click Seed Face and select a seed face for the midsurface.Note: The software uses the thickness of the seed face as the thickness value of the midsurface.
Set the Cliff Angle. The default is 75 degrees.
Preview the generated face to be offset by clicking the Region or Full Boundary preview buttons.
If necessary, adjust the Cliff Angle to ensure that the correct face is selected. When the previewed face is correct, click OK. Note: If Hide Original is selected, the original solid body is hidden; only the sheet body is displayed.
