★Why does the hole geometry change after converting geometry to sheet metal in ZW3D

Issue: 

Why does the hole geometry change after convert to sheet metal in ZW3D?

Causes:

Convert to Sheet Metal is a function driven by selected stationary faces, which generates a sheet metal part with uniform thickness and is commonly used for converting solids to sheet metal.

In the case shown in the figure, the hole is a tapered hole with non-uniform thickness sections, after conversion to sheet metal, a uniform-thickness sheet metal will be generated,

causing the chamfered geometry of the hole to disappear.

Solution:

Method 1

To preserve the geometric shape of the hole, the Mark Bend function can be applied to mark only the transition sections, allowing the marked bends to be unfolded successfully.

1. Execute the Mark Bend command.
2. Select the target face for the Stationary option.
3. Select the input for the Bend faces option.
   
   
   

Method 2

Convert the model to sheet metal, and then proceed to design holes. Execute command Convert to Sheet Metal, convert the solid to sheet metal.

1. Execute command Convert to Sheet Metal, convert the solid to sheet metal.
   
2. Execute the Hole command,and then add hole.
