Urban Design Software: Five Free Software Tools for Urban Planners


Urban design today is more dynamic and visual than ever before. From shaping streetscapes to modeling downtown redevelopments, software has become the foundation of every designer’s workflow. Whether you’re crafting 3D models, illustrating design concepts, or analyzing data to support your projects, digital skills are now as critical as design intuition.

Planetizen Courses offers urban designers a complete pathway to master the industry’s leading design and visualization tools - on your schedule, from anywhere. Below are the five most important software tools for urban designers, and the specific skills you can build for each through Planetizen’s expert-led courses.

1. SketchUp

SketchUp is the most widely used 3D modeling software in urban design. Its intuitive interface makes it ideal for creating massing studies, testing form-based code scenarios, or visualizing public realm improvements.

Five SketchUp skills you’ll learn with Planetizen:

  • Model realistic 3D environments. In SketchUp for Planners: An Introduction, create buildings, streets, and plazas using intuitive push/pull tools.
  • Work with real-world sites. Intermediate Part 1 teaches geolocation, terrain modeling, and importing satellite imagery.
  • Translate zoning rules into 3D. Intermediate Part 2 covers setbacks, height limits, and FAR visualization.
  • Animate your designs. Learn to create fly-throughs and walkthroughs that bring your spaces to life.
  • Render presentation-ready visuals. Intermediate Part 3 teaches how to export and enhance models in Photoshop and Illustrator.

2. Adobe Photoshop

Photoshop is the cornerstone of professional visualization. It helps designers transform simple models or photos into compelling, realistic renderings that tell a story about place and atmosphere.

Five Photoshop skills you’ll learn with Planetizen:

  • Master essential tools. Photoshop CC for Planners 1 introduces layers, cropping, and color correction.
  • Composite professional renderings. Part 2 explores blending, masking, and lighting effects for realism.
  • Build a graphic resource library. Part 3 helps you assemble trees, people, and textures for reuse.
  • Simulate urban transformations. Part 4 shows how to convert a basic street photo into a vibrant “complete streets” rendering.
  • Prepare graphics for reports and boards. Learn how to export layouts for print and digital formats.

3. Adobe Illustrator

Illustrator is the designer’s go-to tool for clean, scalable graphics—essential for creating diagrams, maps, and plan graphics that combine technical precision with visual clarity.

Five Illustrator skills you’ll learn with Planetizen:

  • Understand vector drawing fundamentals. Learn how to use paths, anchors, and layers efficiently.
  • Convert CAD linework into beautiful plans. Refine imported AutoCAD files into presentation-ready graphics.
  • Design conceptual diagrams. Communicate design principles using hierarchy, icons, and color palettes.
  • Create high-quality urban design maps. Combine Illustrator with GIS outputs for accurate, elegant cartography.
  • Export professional deliverables. Format and export graphics for reports, competitions, and presentations.

4. AutoCAD

AutoCAD is still the backbone of technical design for urban spaces. It ensures precision, consistency, and coordination across multidisciplinary teams and projects.

Five AutoCAD skills you’ll learn with Planetizen:

  • Draft accurate 2D site plans. AutoCAD 101 introduces scalable drawing for streets, parcels, and site elements.
  • Illustrate design concepts. AutoCAD for Site Planning teaches how to add layers, hatching, and annotations.
  • Digitize hand sketches. Learn to trace over scanned concepts or aerial imagery for quick iterations.
  • Build 3D massing models. AutoCAD for 3D Modeling guides you through extrusions and spatial visualization.
  • Prepare drawings for print and collaboration. Learn layout setup, scaling, and exporting for design review.

5. ArcGIS (Esri)

Great urban design starts with understanding place. ArcGIS enables designers to analyze the physical, social, and environmental context of a site - informing better design decisions.

Five ArcGIS skills you’ll learn with Planetizen:

  • Build clear, data-rich base maps. Introduction to GIS, Part 1 covers how to visualize zoning, land use, and networks.
  • Manage and import data. GIS Fundamentals teaches data organization and geodatabase structure.
  • Analyze spatial relationships. Use buffers, overlays, and joins to inform design strategies.
  • Design effective map layouts. Apply cartographic principles to communicate spatial ideas clearly.
  • Share interactive maps online. Publish designs on ArcGIS Online for collaboration and feedback.
