N Size Drill
An attachment that marks 4-axis locations eliminates human error during manual layout. Even after painting blasting or galvanizing, the part information is still retained.
The CNC Drill Line can import DXF files and can use them to process 3-D shapes as long as the steel is detailed according to specific rules. Some of these rules might be different to the way you are detailing at the moment and might require some adjustment. This process is not nearly as seamless as the 3-D modeling software solutions above.
