The Rack Builder is still being built. Your racks are kept in this browser, and you can save and open them as .json files.

You can cable ports in 2D: press Cable, then click the port at each end.

Cables are in 3D and in the exports: the sheet, draw.io, the 3D model, the bill of materials and a cable schedule.

Export has an import kit for NetBox and one for Nautobot: types, devices, modules and cables, in import order, with a README.

Set the site and the device role they name under Export, DCIM import settings.
