Tutorials
Start using Inspire with our interactive tutorials.
Parametric Modeling
Create parametric sketches, geometry, and PolyNURBS with construction history and variables.
Implicit Modeling
Create implicit models with primitives, lattices, point clouds, fields, offsetting, Booleans, inverting, smoothing, morphing, and filleting.
Structures
Set up your model and run a structural analysis or optimization.
Motion

Motor or Actuator Joint is Locked

Condition

The joint where the motor or actuator has been applied is set to Locked, so the motor or actuator cannot move.

This error message has two versions:

Motor Joint is Locked
Actuator Joint is Locked

Remedy

Click the Fix button to unlock the joint. This will set the joint state to Active.
