I want to make a pendulum in Create.

I want to do a simple scene using a sphere and a shaft (modified cylinder) and make it swing back and forth. So I am thinking I need to connect the sphere and the shaft somehow, so it is one object. And then “fix” the top of the shaft so it can only rotate along one axis and thereby swinging.

Any tips and trix?

You should be able to use physics and joints.

  1. Select the sphere and cylinder and create a fixed joint - Create->Physics->Joint->Fixed
  2. Select the cylinder and create a spherical joint - Create->Physics->Joint->Spherical
  3. Move the spherical joint to the position at the top
  4. Select the axis that you need

@Jack_Jensen ,

I think this tutorial page have something similar you can reference, look at step4 for collision setup.
