Scale Keep History

Scale Keep History

File: Part_Document_Scripts/Scale_Keep_History.py
Version: 1.0
Document Type: Part (also works with Part inside Product or Process)

Description

Scales selected hybrid shapes about a centre point by a user-defined ratio, preserving the original name of each shape. The result is a live parametric feature — the source shape is kept as an input and the centre point or ratio can be edited after creation.

Requirements

Requirement	Value
Python	>= 3.10
pycatia	>= 0.8.3
wxPython	Required
Open document	Part, or Part inside Product/Process

Usage

1. Open a CATPart document containing hybrid shapes and a point
2. Run the script
3. Selection 1: Select the hybrid shapes to scale (multi-select supported)
4. Selection 2: Select the centre point for the scaling operation
5. A dialog appears — enter the scale ratio (e.g. 2.0 = double size, 0.5 = half size) and click OK
6. Scaled shapes are created inside the current in-work geometric set

---

Output

• Scaled shapes are added to the current in-work geometric set
• If the in-work object is not a geometric set, a new geometric set named Scale_Keep_History is created
• All results are live parametric features — they retain a link to the source geometry and can be edited

---

Notes

• Enter a ratio greater than zero; values less than 1 reduce the size, values greater than 1 increase it
• The source shapes are not modified
• Use this script when you need to keep the parametric history; use Scale Keep Name when you want isolated datums instead
• For scaling all shapes in a geometric set while keeping the full structure use Scale Keep History And Structure
