Scale Keep History And Structure

Scale Keep History And Structure

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

Description

Scales every hybrid shape inside a selected geometric set about a centre point by a user-defined ratio, recreating the full geometric set structure in the current in-work object and preserving the original names of all shapes and geometric sets. Recurses through all child geometric sets automatically. Results are left as live parametric features with a link to the source geometry.

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 a geometric set and a point
2. Run the script
3. Selection 1: Select the geometric set to scale
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. The scaled structure is created inside the current in-work geometric set

---

Output

A child geometric set named after the source is created inside the in-work object, containing the full recreated structure with all shapes scaled as live parametric features:

[in-work object]
  └── SourceSetName
        ├── Shape_A
        ├── Shape_B
        └── ChildSetName
              ├── Shape_C
              └── Shape_D

Notes

• All results are live parametric features — they retain a link to the source geometry and can be edited
• The source geometric set is not modified
• The selected geometric set must not be the current in-work object — the script will exit with an error if this is the case
• Use this script when you need to keep the parametric history; use Scale Keep Name And Structure when you want isolated datums instead
• For scaling individual selected shapes rather than a whole set use Scale Keep History
