Ignore Thickness

This option controls what unique board types are listed in Lumber tab.

When Ignore Thickness is set unique board types are determined using the material type only ignoring thickness. All parts with the same material type or appearance, depending on the Use appearance setting, will be mapped to the same board type with a single thickness equal to the thickest of all parts of that material type.

Shown here is a mapped board created with three part of the same material type but with 3 different thicknesses and Ignore Thickness set. This example has the Create Board as Glass option set for effect.
