**[NEW FEATURE] Hole Selection Wizard - Select circles/arcs by diameter, color, line type and layer**

Hello LibreCAD community!

I am a progressive die designer and I have been using LibreCAD for 2D technical drawings. I needed a way to quickly select specific hole features (bolts, pins, columns, etc.) based on their properties, so I developed the **Hole Selection Wizard**.

## What it does

The Hole Selection Wizard adds a new command under **Tools → Select → Hole Selection Wizard** that allows you to select circles and arcs by:

- **Diameter** (with tolerance)
- **Color** (ByLayer or custom color)
- **Line type** (ByLayer, Continuous, Dash, Dot, DashDot, DashDotDot, Center)
- **Layer**
- **Apply to**: entire active layer or a user-defined rectangular area

**Safety feature:** The wizard only selects entities on visible (non-frozen) layers, preventing accidental modification of hidden geometry.

## Workflow

1. Open **Tools → Select → Hole Selection Wizard**
2. Set your filters
3. Choose search area (entire layer or draw a rectangle)
4. All matching circles/arcs are selected
5. Apply any LibreCAD operation (move, copy, delete, attributes, etc.)

## Source Code

The source code and integration instructions are available on GitHub:

https://github.com/emreonen/librecad-hole-selection-wizard

The integration requires modifying a few existing files (`rs.h`, `lc_actionfactory.cpp`, `lc_menufactory.cpp`, `lc_actionhandlerfactory.cpp`, `src.pro`) — full instructions are in the README.

I hope this is useful for other mechanical designers using LibreCAD. Feedback and contributions are welcome!

Best regards,
Emre

This is great!

You could fork LC and enable the workflow to create distributions.

oh, this great indeed.

Yet conditional search is almost available in LC - it's implemented and will be available soon as I'll merge my PR https://github.com/LibreCAD/LibreCAD/pull/2540

It includes functionality for selecting entities based on their properties and conditions.

Hope I'll commit it one of these days, it should be available in 2.2.2-alpha branch
