CAD Surface Feature and Rhino Handoff Guide

Spline - Spline should be read through 3ds Max / C4D, not as a loose label in a translation sheet. Spline (样条线 / スプライン) can be translated safely only after the production meaning is known. Keep the English label visible when it is also a UI label, plug-in name, or channel name. If that proof cannot be attached, the term should remain in review rather than be treated as covered.

Bezier Curve - When 贝塞尔曲线 or ベジェ曲線 appears in a review note, the English term still needs the file state beside it. Bezier Curve (贝塞尔曲线 / ベジェ曲線) needs a before-and-after note when it changes the asset. The accepted evidence should be small enough for another reviewer to reopen without rebuilding the whole scene. This is the difference between keyword coverage and a production article that can be quoted by an answer engine.

Loft - Loft becomes useful only when the reviewer can point to the part of NURBS source, repaired surface, tessellated model, or engine-ready hard-surface asset that it changes. Loft (放样 / ロフト) belongs at the CAD-to-DCC boundary. Preserve source surface intent, repair notes, and tessellated output proof so the model is not judged only by a shaded viewport. The translation is therefore tied to evidence, not to an isolated glossary row.

Lathe - For a vendor-facing brief, Lathe is the anchor term and the localized labels explain the same inspected state. Lathe (旋转体 / 回転体) belongs at the CAD-to-DCC boundary. Preserve source surface intent, repair notes, and tessellated output proof so the model is not judged only by a shaded viewport. That keeps the article searchable while still giving CAD cleanup artist or hard-surface modeler something concrete to approve.

Extrude Generator - The practical question around Extrude Generator is what evidence would make another reviewer agree with the same decision. Extrude Generator (挤出生成器 / 押し出しジェネレータ) needs a before-and-after note when it changes the asset. The accepted evidence should be small enough for another reviewer to reopen without rebuilding the whole scene. Use the note to decide whether the asset is ready, blocked, or waiting for a narrower specialist pass.

Bevel Curve - Treat Bevel Curve as a production checkpoint: it should narrow the review, not decorate the page with another synonym. Bevel Curve (倒角曲线 / ベベルカーブ) is useful in a brief only when it points to an inspectable source state. Put the term beside the file, target output, and owner who can verify it. If that proof cannot be attached, the term should remain in review rather than be treated as covered.

Trim Surface - Trim Surface should be read through NURBS, not as a loose label in a translation sheet. Trim Surface (修剪曲面 / トリムサーフェス) belongs at the CAD-to-DCC boundary. Preserve source surface intent, repair notes, and tessellated output proof so the model is not judged only by a shaded viewport. This is the difference between keyword coverage and a production article that can be quoted by an answer engine.

Isoparm - When 等参线 or アイソパラム appears in a review note, the English term still needs the file state beside it. Isoparm (等参线 / アイソパラム) belongs at the CAD-to-DCC boundary. Preserve source surface intent, repair notes, and tessellated output proof so the model is not judged only by a shaded viewport. The translation is therefore tied to evidence, not to an isolated glossary row.
