Announcing Tangram Pro™ v1.5 :tada: Our biggest update yet!

:star2: New Projects

Organize your work with new Projects. Within a project you can design a component-based system and generate code.

  • Connect projects together for extended capabilities.
  • Collaborate on system designs, add other users to your project, and set their level of editing privileges.
  • Integrate projects with GitHub or GitLab repositories.

:star2: Enhanced Design Tools

System design just got a lot faster.

We took a fresh look at the design process and developed a completely new, more intuitive workspace for building component-based systems. These enhancements shorten the time it takes to lay out a system, define interfaces, and help prevent design mistakes.

  • New design tools, and objects to quickly build out your system.
  • Message flow visibility and validation to prevent design mistakes and highlight incompatible interfaces.
  • New tree view of components makes it easier to see all the elements of your system and subsystem at a glance.

:star2: Streamlined Code Generation

From design to code, now simpler than ever.

  • With streamlined toggles to Generate Interface Code, Compile and Containerize, code can be generated from your design with the simple click of a button.
  • Generate code for multiple components at once.
  • Quickly access previously generated code in Project Runs.

:star2: Containerize Your Code

  • Automatically place generated code into Docker containers with the new Containerize option.
  • Immediately run and test your code using Docker.

Tangram Pro™ v1.5 includes several under-the-hood enhancements and bug fixes. Check out our User Guide for more information about Projects and designing systems.
