Grain constrained is used to make parts align with the plate reducing the number of rotations needed to cut the parts.
Let’s discover an example of when to use grain constrained.
In this example, a quantity of 50 parts is nested. There is one rotation of the plate needed to complete the nest. Learn more about how to nest in our resource center.
Let’s add “Grain Constrained.”
- Select Edit on the part, then select “Grain Constrained.” Finally, select “Update Item.”
3. Select “Clear All Nests.” Then renest the items.
4. The single part nest is now placing the parts on the sheet with no rotations needed due to “Grain Constrained” being selected.
Let’s explore an example of a multi-part nest without “Grain Constrained” selected.
1. When multi part nesting, SecturaFAB maximizes material usage; however, multiple rotations are needed to complete the cutting of this nest.
2. With “Grain Constrained” selected, the nested part placement maximizes the material usage and places the shapes that best reduce plate rotations.
Another benefit of “Grain Constrained” is limiting waste of material by rotating the parts in the CAD editor. Let’s discover how.
1. Select “Edit” on the CAD line item.
2. Select “Rotate.” In this example we rotated our part at a 90-degree angle. Select “Done.”
3. When renested, the part placement on the sheet now considers “Grain Constrained” and the angle of our DXF part.
