I didn´t even know the command "element", because I can´t find in the command boxes.

I´ll take a look at the user´s guide.

The command is the second item in the "point" menu. However, using the "nice names" which is default displays that as "Point On" which is a much better description of what it actually it and does.

Here is how to make an animated triangle.

Geometry, Plot view.

1. Cmds->plot->Function, type sin(x)
2. Cmds->point->point on, select somewhere on your function and press ENTER. You will see a docked "B" in the corner, and a point appear. Hold down on the B and a slider comes up. Drag it around and B will move.
3. Cmds->point->point. Move to two separate locations and press enter at each one. Points C and D will be made.
4. Cmds->polygon->triangle. Selecte the 3 points one after another with enter. A triangle will be made.
5. Hold down on the B again and press EDIT on the menu when it appears. Turn on animation. Exit the dialog. Press ESC to hide the slider. Your triangle will being to move.


The "user guide supplement" had many details on the new geometry application. Unfortunately, it couldn't be rolled into the main document at that time for various reasons which is why it ended up as a "supplement".
