The measurement function of markups is currently right click to indicate the end, I want to change it to middle click to end, right click to rotate the model. I didn’t find anywhere in markups about mouse event handling, how I should do that.

You can use the `SetEventTranslation` method to change keyboard and mouse event mapping to widget events. You can find examples on this forum and in the script repository.
