01
Plane cut → Two split modes
Use Auto Slice to Fit for build-plate-aware straight cuts, or choose the higher-cost cloud AI Semantic Split when natural part boundaries and hidden-surface completion matter.
Migration guide
If you miss Meshmixer, this is the new path.
The same goals — split big models, add connectors, fix geometry, export parts — with a workflow built for current web-based print prep.
Meshmixer concepts, TooBig3D workflow
A practical crosswalk for makers who already know the old manual process.
02
Manual connectors → Alignment Pegs
Generate dovetail, round, or square pegs with material-aware tolerances.
03
Manual labeling → Part Labels
Emboss hidden labels on connection surfaces so assembly stays organized.
04
Repair pass → Mesh Repair
Clean non-manifold edges, holes, and bad geometry before you export.
● Cut for printer volume
● Add alignment automatically
● Export organized parts
