Loft

Status: Implemented

Loft rails a solid across two or more ordered sketch or face sections: one surface curve per station, from the first section to the last, capped at both ends.

Walkthrough

Inputs

• id – a string, default null.
• profiles – a multiple reference_selection filtered to SKETCH and FACE, default []; an ordered list of section references.
• consumeProfileSketch – a boolean. When true (default), removes source sketches after a successful loft. A face section consumes nothing.
• guide – a single (multiple: false) reference_selection filtered to EDGE, default null; the spine the sections follow.
• rotateToGuide – a boolean, default false. With a guide, rotate sections into the guide's moving frame rather than retaining their own orientations.
• boolean – a boolean_operation, default { targets: [], operation: "NONE", mergeCoplanarFaces: true }.

Behaviour

• Each section contributes its profile's outer loop curves in world space. Multi-region and holed profiles loft: each region rails across the sections into its own solid, each hole lofts into a cutter that is subtracted, and the region solids union into one result.
• Face naming: side face i takes the first section's edge name with a _LF suffix (or EDGE_LF when unnamed). Each region's caps are keyed by its first-section loop id as {base}:L{loopId}_START and _END; {base}_START and _END are container aliases for those families. base is the feature id or Loft. Loft side names carry no feature-id prefix, unlike Sweep.

Limitations

Every one of these is a loud error, never a silently dropped or twisted surface:

• Fewer than 2 sections fails (need at least 2 section profiles).
• Any section's outer loop must have at least two curves.
• Every section must share one loop structure: the same region count, the same hole count per region, and the same curve count per loop. A mismatch is an error naming the two sections and the counts that differ — it is not tolerated by resampling.
• A profile name that resolves to neither a sketch profile nor a face fails with profile '…' not found.
• A guide that does not resolve, resolves to no curves, or resolves to a multi-segment chain is refused; guided loft accepts exactly one spine curve.
