3D surface cleanup

3D surface cleanup clears eligible walls and floors at the deepest retained Z of each step. Use it to clean residual step geometry; it is not a general-purpose replacement for 3D surface finish. Select one or more imported models; several targets are cleaned up together.

Requirements

Requirement	Value
Target features	One or more 3D model features; regions can limit the cut
Tool	Flat or ball endmill
Passes	Finish only

Parameters

Shared settings are documented in Common operation parameters.

Parameter	Description
Pattern	Chooses Offset, Seeded circles, or Parallel floor coverage.
Finish walls	Enables eligible wall cleanup.
Finish floor	Enables eligible floor cleanup.
Stock to leave	Leaving material changes what a finish pass can reach.

Strategies

The floor patterns are covered by Clearing patterns and Seeded-circle clearing. Cleanup does not offer Trochoidal, Waterline, or Constant scallop patterns.

Limitations

Neighbouring models that are not targeted remain protected from their top down, including levels below their bottom. Cleanup can therefore leave material beside or beneath a neighbour; inspect the remaining walls and floors before changing the target or machining order.

Cleanup may have nothing to cut

Cleanup follows retained step depths and only emits the enabled wall or floor work. If stock to leave, a region, or protection removes that work, the result can be intentionally sparse.

Verifying the result

Confirm independently that the wall and floor passes appear where expected, then inspect the remaining surface in 3D before exporting.
