Use the Quad to access tools to create a flat or unfolded representation of your model.
For production, you can save your unfolding to a DXF file.
The DXF file contains all necessary information, such as: bend positions, radiuses, angles of bending, overall dimensions, material and its thickness.
Depending on the material and production tools, the length of unfolded representation may vary.
Bend tables are a more reliable way to express material deformation properties and this information can be stored in CSV file, which can be attached to the model.
After applying a bend table, you can see the size of unfolding has changed.
