Each stable release of SheepMetal is listed below, newest first. These notes describe what changed for you as a user — no setup required, just update the plugin to get the latest version.
0.9.9#
Features#
- Bend Correction Table: new compensation strategy. Looks up a correction from thickness, inner radius and angle; flat length = sum of flange lengths + correction. Nearest match on thickness and radius, linear on angle.

Improvements#
- Faster classification, most noticeable on large parts.
- More robust overall.
0.9.7#
Bug Fixes#
- More robust tolerance handling.
0.9.6#
Bug Fixes#
- More robust hem handling in edge cases.
0.9.5#
Features#
- Experimental Sheet To Non-Manifold and Sheet Editor components.
Bug Fixes#
- Fixed lookup tables for K-factor strategies.
0.9.3#
Bug Fixes#
- Bend direction detection is more robust in edge cases.
- Correct trims for angled hems.
0.9.1#
Bug Fixes#
- Unroll: null inputs keep the tree structure and return null in place.
0.9.0#
Features#
- New corner relief options.
- Faster edge relief processing.
Improvements#
- Faster classification.
Bug Fixes#
- Sheet Info: null inputs no longer return wrong trees.
0.8.0#
Changes#
- Default setback changed from 1 to 0.5 × thickness.
- The extension of inner bend relief cuts is now a fixed value.
Improvements#
- Faster relief cut detection and creation.
Bug Fixes#
- Hems work again in Rhino 8.27+.
- Relief cuts are created correctly on some complex parts.
- 180° hems give the same result on Mac and Windows.
0.7.4#
Bug Fixes#
- Flat parts allow a small angle tolerance for minor inaccuracies.
0.7.3#
Improvements#
- More stable bend detection for angles near 0° or 180°.
- Invalid sheets now always raise an error.
0.7.2#
Bug Fixes#
- Two faces joined by more than one edge are handled correctly.
- Fewer fillet failures during relief cut creation.
0.7.1#
Improvements#
- The Sheet parameter supports transforms.
- One tolerance system shared by all components.
- Faster Brep To Sheet components.
- Error codes for easier troubleshooting.
Bug Fixes#
- Non-Manifold To Sheet no longer fails when switching from parallel to single-threaded.
- More reliable edge detection on complex parts.
- Unroll no longer sets the bend radius to 0.
0.7.0#
Features#
- Flange: offset on both sides and taper.
- Unroll: new Back Side Up input.
Bug Fixes#
- More reliable hem detection.
0.6.2.3#
Bug Fixes#
- Non-Manifold To Sheet: the bend direction flip works in Rhino 7.
0.6.2#
Changes#
- New bend detection: more accurate and faster. Results may change for some parts.
0.6.1.0#
Bug Fixes#
- Flat relief cuts.
Improvements#
- Non-Manifold To Sheet rebuilds from the root face for consistent results.
- Faster Non-Manifold To Sheet and Manifold To Sheet.
0.6.0.1#
Bug Fixes#
- Joining Breps retries with larger tolerances, so complex parts join more often.
0.6.0.0#
⚠ BREAKING CHANGES#
- Non-Manifold To Sheet: the root face defaults to the first face, not the largest.
- Manifold To Sheet: no longer picks the largest face as root. Set the root face explicitly.
- Non-Manifold To Sheet: Flip Normals is renamed Flip Offset.
Features#
- Non-Manifold To Sheet: new Flip Bend Direction input.
- New Tolerance component for headless Rhino.
- New SM Changelog component that shows the installed version's notes.
Bug Fixes#
- Adjusted the depth of inner bend relief cuts.
- More reliable relief cut detection.
0.5.0#
- Initial release.
