[#1]

I create a engine assembly and used "Drive Constrain" to rotate the crank shaft. The animation shows the crank shaft turns continuously in one direction. However, when I animate the constrain in Inventor Studio, the crank shaft turned in two different directions (see the vide file attached).

May I know why the crank shaft turns different direction?

Thanks

Which of the 3 Angle Constraint types did you use?
Can you use Dynamic Simulation and Publish to Studio instead?

[#3]

Not matter I used Directed Angle or Undirected Angle, it is still the same. I created a animation by using "Drive Constrain"  and the crank shaft shows only one direction. Please see the file attahced.

Any reply?

Attach your assembly here.

As the file is too big, so I zipped into 3 files. This is the 1st zip file.

[#7]

This is the 2nd one

[#8]

This is the last one. Please unzip the 3 zipped files into one folder.

Make sure the planes used for the angle constraint share the same axis.

I used the assembly origin YZ and the DLM-006 YZ planes for the angle constraint and it worked fine in Studio.

Thanks. It solves my preoblem.
