One of the new features in version 6 is the ability to visualize forces in the modelview. The easiest way to do this with a loaded model is to right-click anywhere on the model in the modelview and select the following in the context popup menu:
Main->Forces->(Auto-Generated View)Show
This will show a visualization of the current forces in the model. For example: The reaction forces will be shown as Black arrows with red tips (you can hover the mouse over a force arrow to see which one it is).
Please note that the simulation needs to be in a state where forces have been calculated for any forces to be shown (for example during Inverse Dynamics).
How/Is it possible to visualize only certain forces to increase clarity (selection/deselection of force groups, e. g.)?
I assume that the lines which are sometimes longer than the arrows represent the magnitude of forces. Is it possible to adjust line and/or arrow lengths?
Can this be read somewhere in the documentation/tutorials. (Could not find it yet.)
Thomas,
I have to admit that this is still a little work in progress, so there is not much info available. It is more to give a quick overview. Several of the things you are asking for do not exist yet.
