## One rack, fully documented

Explore the DC42 42U rack, adapt a fictional example with eight server footprints and 40 modeled connections, and export a label schedule, equipment register, connection register, verification checklist and editable project.

The 3D model is optional and loads from Rackstamp only when requested. The source is the owner's DC42_Interactive.blend. Removable doors are omitted so the equipment is visible. The model always shows the DC42 example; editing project records does not move or change its equipment.

Choose a local site, hall and rack scope. Keep a stable cable ID and choose far-end, fixed A/Z, or local HERE/THERE text. Use @ before an endpoint to enter its full scope. Checks identify duplicate IDs, overlapping U footprints, repeated endpoints, missing values and text that exceeds the estimated print area.

Everything entered stays in the current browser tab. Download a project JSON to resume later; reloading clears unsaved changes. All exported records remain Draft or Fictional example; field verification requires actual evidence. CSV exports are label text, not printer-specific layouts.
