## Set up one rack and review imports

1. **Start a local rack**

   Start a local rack.

   This free anonymous tool keeps one person’s straight lengths in this browser. The practice rack is synthetic.

2. **Give the rack a fixed code**

   Give the rack a fixed code.

   Rack codes stay exact and cannot change once used.

3. **Name the practice rack**

   Name the practice rack.

   Choose millimetres before creating this rack. The unit stays fixed. The usual 2 mm uncertainty becomes fixed after the first piece.

4. **Create the rack**

   Create the rack.

   The usual 2 mm measuring uncertainty will be deducted from measured lengths.

5. **Open the CSV import**

   Open the CSV import.

   Materials need all seven properties. Bins need an explicit family and a length limit.

6. **Review prepared material rows**

   Review prepared material rows.

   The leading zeroes in 000017 stay exact. Read the preview before adding the whole file.

7. **Adopt the material**

   Adopt the material.

   This adds one reviewed material; changing its identity later needs a new material code.

8. **Review prepared bins**

   Review prepared bins.

   The bin belongs to R1, allows AL and holds measured lengths up to 6000 mm.

9. **Adopt the bin**

   Adopt the bin.

   All rows are adopted together. A piece must fit both the family and measured-length limit.

10. **Review a conflicting file**

   Review a conflicting file.

   This file contains one new material and the already-used 000017 code.

11. **See the whole import refused**

   See the whole import refused.

   A duplicate identity refuses the entire file, including its first valid row. Existing work remains.

12. **Keep the accepted setup**

   Keep the accepted setup.

   Cancel the refused preview. The accepted rack still has one material and one bin.
