C3DT Constrainer

Fast & Reliable Constraints in Inventor

What is the C3DT Constrainer Inventor app?

The C3DT Constrainer is a powerful Autodesk Inventor add-on that automates one of the most repetitive tasks in mechanical design: applying constraints. Instead of manually selecting origins, planes, and axes for each part, the Constrainer applies them instantly and correctly. It’s built by engineers who use Inventor daily and know the pain points of assembly work inside out.

With Constrainer, you spend less time clicking through menus and more time creating designs that matter.

In complex assemblies, applying constraints the “right” way — using planes and axes rather than faces — is time-consuming. Most designers take shortcuts, which often leads to:

  • Lost constraints after geometry changes

  • Assemblies that behave unpredictably

  • Extra hours fixing broken links

  • Frustrating rework during revisions

Constrainer eliminates these issues by handling constraints properly and automatically.

What the C3DT Constrainer inventor app Does

  • Automates Constraints: Select a reference part and target parts, and Constrainer applies all the necessary plane/axis constraints in seconds.
  • Saves Time: A task that takes ~5 minutes manually can be done in ~10 seconds. Multiply that across dozens of parts, and the savings are massive.
  • Improves Reliability: Constraints stay intact when geometry changes, reducing errors and rework.
  • Works at Scale: Ideal for large assemblies with many subcomponents.
