I have a red time bar, but I can't find any errors. Can anyone give me some examples of errors that will make the time bar turn red, thank you.
It's usually because of the mates which are being not solved in motion studies.
As Deepak indicated, red means that the positions can't be solved. This generally means that there is a conflict between mates, motors and geometry. If everything is working up to a point and suddently the timeline goes red, generally you have reached a geometric limit like in the image below of the car jack. If you turn the crank to lower the jack, at some point the distance between A and B is as much as the geometry will allow. If you try to continue turning the crank, there is no solution so the timeline goes red.
If you post the model, I'd be happy to look at it. Sometimes it just takes another set of eyes to see the problem.
