ArcGIS Urban vs Modelur Comparison: Reviews, Features, Pricing & Alternatives in 2026

ArcGIS Urban is a web-based 3D platform designed to transform how you approach city planning and real estate development. You can move beyond static 2D maps by creating immersive 3D models of your entire city, allowing you to visualize proposed buildings and zoning changes in their actual context. It helps you streamline the planning process by providing a centralized location for all your spatial data, development projects, and long-term plans.

You can use the platform to evaluate different planning scenarios and automatically calculate how new developments will impact population growth, job creation, and traffic. It is built for urban planners, real estate developers, and local government officials who need to communicate complex ideas to stakeholders clearly. By using data-driven insights, you can make more informed decisions that shape the future of your community while ensuring transparency throughout the public review process.

Modelur is a specialized parametric tool designed to streamline your urban planning and design workflows within SketchUp. Instead of manually calculating complex zoning numbers, you can create 3D building masses that automatically update their data as you scale or move them. It helps you stay compliant with local regulations by providing instant feedback on land use, building heights, and density requirements.

You can quickly generate multiple design iterations and compare their financial or environmental impacts through live data syncing. This eliminates the need for tedious spreadsheets and manual area tracking, allowing you to focus on the creative aspects of city planning. Whether you are designing a small neighborhood or a large-scale master plan, it ensures your 3D models remain data-rich and technically accurate throughout the entire design process.

• 3D Scenario Modeling Create and compare multiple design alternatives in 3D to see how different zoning rules change your city's skyline.
• Zoning Automation Apply complex zoning parameters to your 3D models automatically to visualize maximum building envelopes and floor area ratios.
