SmartCluster: Common Line and Common Crop Cutting now provides an easier way to do Commonline Cutting.
To save cutting, and to avoid thin skeleton pieces, it is sometimes necessary for two parts to share a common cut line. This tutorial shows how this can be achieved.
1Open the Nesting mode.
2Click Open parts from database 
3Search for Parts that have 'Common Line Cutting' as their workorder invoice number (make sure to select "Show All" and "All Cut By Dates"). Open them all.
4Click Open Plate 
5Click Create New Plate 
6Enter the following details
Plate Material |
GR250(A36), 20.00mm |
