Why does a part look stretched after scaling?

为什么缩放后部件会被拉伸？

A part stretches because Scale is applied per part in the SG panel, while its Parent ID, Anchor X/Y, and the offsets in its action units still follow the old values. The child keeps the old anchor and offsets, so rotation and offset pull it out of proportion.

部件被拉伸，是因为 SG 面板里的 Scale 是按部件单独生效的，而它的 Parent ID、Anchor X/Y 以及动作单元里的偏移量仍沿用旧值。子部件保留旧锚点和偏移量，旋转和位移就会把它拉变形。

How to do it in 3SAX V3

在 3SAX V3 里怎么做

1. Open the SG panel and select Part ID. Check Parent ID, baseX/baseY, Anchor X/Y, Scale, Layer, Z-perspective.

1. 打开 SG 面板，选中 Part ID，检查 Parent ID、baseX/baseY、Anchor X/Y、Scale、Layer、Z-perspective。

2. Set Anchor X/Y to the joint you rotate or scale around. A wrong anchor stretches the part.

2. 把 Anchor X/Y 设在旋转或缩放的关节上；锚点错了，部件就会拉伸。

3. If the part is bound in BONE, recheck its joint weight before scaling.

3. 如果部件已在 BONE 里绑定，缩放前先核对其关节权重。

4. Open the AG panel. In the action unit, fix seq (e.g. 01:0-5), relative rotation, scale, X/Y offsets, swap part.

4. 打开 AG 面板，在动作单元中修正 seq（如 01:0-5）、相对旋转、缩放、X/Y 偏移、swap part。

5. Use auto-suggest sequence to rebuild a seq that matches the part's numbered states.

5. 用 auto-suggest sequence 按部件的编号状态重新生成 seq。

6. Open CANVAS. Drag to adjust dx/dy and edit rot/scale; changes sync back into the codes.

6. 打开 CANVAS，拖动调整 dx/dy，编辑 rot/scale，改动会同步回代码。

What you CAN and CANNOT do

能与不能

CAN: scale a single part, adjust anchor and offsets, sync fixes from CANVAS.
CANNOT: auto-fix stretched parts. If you scale a parent but not its children, they fly apart on render or validation rejects the codes.

能：缩放单个部件，调整锚点与偏移，在 CANVAS 里同步修正。
不能：自动修复拉伸。若只缩放父级而不处理子级，渲染时部件会散开，或校验拒收代码。
