Supported scales
ArchMM supports full size and common architectural scales through 1/16" = 1'-0", converting in either direction between full-size dimensions and model millimeters.
Printer-bed checks
Included presets cover common Prusa, Bambu Lab, Creality, Ender, and Anycubic beds. Always confirm orientation and clearances in the slicer before printing.
Offline use
ArchMM works without an account or network connection and keeps the selected scale and printer on the iPhone.
