Move Objects to Specified Z Coordinate

Rhino Python script for moving selected objects or control points to a specified Z coordinate value.

Features

• Manual input or text object selection for Z value
• Automatic number extraction from text (e.g., “SFL 0.95” → 0.95)
• Remembers last input value as default
• Supports moving objects and control points
• Input unit: meters, processing unit: millimeters

Usage

Input Number

1. Run script
2. Enter number (e.g., 1.5)
3. Select objects to move

Select Text

1. Run script
2. Click text object containing number
3. Select objects to move

Move Control Points

4. Enter or select target Z value

Supported Text Formats

• SFL 0.95 → 0.95
• Level 1.23m → 1.23
• -1.5 → -1.5
• Height: 2.8m → 2.8
