I am looking for a way to create temporary geometry via API, like lines or circles. Can someone point me to some API commands for this?
For example, when I use the evaluate -> measure tool via the user interface and select two vertices, several lines emerge showing their distance (red, green, blue, black). There are also black circles on the two selected vertices. This is the kind of temporary geometry I am looking for.
Note: I do not want to use temporary bodies, as their visible width changes when I zoom in and out. I want the objects to have the same size no matter what zoom level I have.
