Grasshopper to fabrication: closing the loop on CNC handoff
The geometry is the easy part. The win is a definition that emits cut-ready DXFs your fabricator opens without a single phone call.
Most parametric work stops at the pretty render. The part that actually saves a project is the unglamorous end of the pipe: the moment geometry becomes a file a CNC operator can run.
The handoff is the deliverable
A Grasshopper definition that produces nested, labelled, tolerance-checked DXFs is worth more than one that produces a flawless model. The fabricator never opens Rhino. They open the cut files — so the cut files are the product.
If the fabricator has to call you to interpret the file, the automation has not finished its job.
We build the nesting, layer naming, and kerf allowance into the definition itself, so a design change re-emits a correct cut set instead of starting a new round of manual cleanup.
