Chamfer Edges
chamfer_edgesBevel selected edges of a 3D part by a specified distance, with validation to ensure the result remains a valid solid.
Instructions
Chamfer (bevel) specific edges of a shaped Part object — the direct-shape counterpart to fillet_edges.
handle: handle of the object to chamfer (e.g. 'box_1', a boolean result). edges: non-empty list of edge references. Each may be a tag ('e_...' from list_edges, preferred), an 'EdgeN' string, or a bare 1-based integer index. size: symmetric chamfer leg distance in mm (applied equally to both faces meeting at the edge, i.e. dist1 = dist2 = size). Must be > 0. Default 1.0. name: label for the resulting feature object. Default 'Chamfer'. per_edge: add the edges one at a time, validating after each, instead of in a single apply. Slower; for geometry known to be blend-hostile. allow_partial: accept a partial result instead of aborting. Off by default.
The base object is hidden (consumed into the chamfer feature). Validated exactly like fillet_edges (issue #283) — Shape.isValid(), unchanged solid count, no growth of the tight bounding box — before a handle is issued.
Returns {handle, name, volume (mm^3), edges (resolved 1-based indices actually chamfered), checks {valid, solids, envelope_ok, envelope_growth_mm, envelope_tol_mm}, mode ('batch' | 'per_edge'), partial}; when partial is True, also skipped_edges and a warnings entry. On a failed check the feature is removed from the document and BlendCheckFailed is raised naming the offending edges — never a handle to corrupt geometry.
