Inkscape is a powerful vector graphics editor perfect for creating scientific diagrams, technical illustrations, and publication-quality graphics.

Objects vs Paths

Understanding the difference between objects and paths is crucial:

  • Objects: Basic shapes (rectangles, circles) with editable properties like corner radius
  • Paths: Mathematical curves with editable nodes and control points

Convert to path when you need:

  • Custom stroke positioning
  • Node-level editing
  • Complex shape modifications

Convert objects to paths: Path → Object to Path or Ctrl+Shift+C

Basic Workflow

  1. Set up guides: Create alignment guides first (Object → Guides)
  2. Plan layers: Use layers for complex drawings (Layer → Add Layer)
  3. Use clones: For repeated elements (Edit → Clone or Alt+D)
  4. Organize objects: Group related elements (Ctrl+G)

Essential Shortcuts

  • F1 - Select tool
  • F2 - Edit paths by nodes
  • F4 - Rectangle tool
  • F5 - Circle/ellipse tool
  • F6 - Polygon/star tool
  • T - Text tool
  • Ctrl+D - Duplicate
  • Alt+D - Create clone
  • Ctrl+G - Group objects
  • Ctrl+Shift+G - Ungroup

Working with Text

Basic text formatting:

  • Select text tool (T)
  • Click and type
  • Format with Text → Text and Font

LaTeX Integration

For mathematical expressions, use proper font sizing:

\fontsize{11pt}{1em}{$p_1$}

Extensions for LaTeX:

  • Install TexText extension for complex equations
  • Use Extensions → Text → TexText for inline math

Guides and Alignment

Create guides:

  • Drag from rulers
  • Object → Guides → Create Guides Around Page
  • Snap to guides: View → Snap Controls

Clones and Patterns

Clones update when original changes:

1. Create original object
2. Select and clone (Alt+D)
3. Position clones
4. Edit original to update all clones

Tiled clones for patterns:

  • Edit → Tiled Clones
  • Set rows, columns, and transformations

Export Tips

For publications:

  • Use high DPI (300+ for print)
  • Export as PNG: File → Export PNG Image
  • For vector output: Save as PDF or EPS

Inkscape excels at creating precise technical graphics and integrates well with academic publishing workflows.
