Is it possible to get a part to move and stop and move and stop again in simply motion?  How is this achieved?
Attempting Spline function but keep on getting errors.

RE: intermittent motion

Hi Alan,

Spline is the way to go. Enter several consecutive (in time) points at the same value to create a "flat" section in your spline in order to have a pause in your movement.

Some advice:
- if you get a crash, it might be because you said a part was ground when it should have been moving
- if you get an error, it must be because something is not correctly set-up in your simulation. Review the properties of the joints and make sure nothing is conflicting.
- also, if you create joints manually like two translationnal joints for the same part for example (one in X, the other in Y), you might create a conflict because one joint is blocking the other one. In such a situation, a planar joint should be used instead.
- you should try the manual method : say 'no' to the question when entering motion the first time. then select yourself your moving and ground parts (as you go, check that the appropriate joints are added). Don't add ground parts that are not usefull to create a joint : just leave them in 'assembly components'. Also, use 'attach to' when you have a part that doesn't move relative to a moving part. This will simplify your joint section.

Simply motion works great once you've understood how it works.

I agree, I need to understand how Simply Motion and Spline in particular works. There is very little in Help.  Can anyone give links to tutorials or guidance in this area.
