I have the Logitech Marathon Mouse M705 that I have seen other users on the forum discussing and using. I would like to configure it and I see this explanation. I have the same question but need a much more basic step by step answer starting with using the Logitech Control Panel ie. what I should set each mouse control to…and then the Rhino preferences ie. how to get to them and what to set each one to. I am an absolute Rhino beginner using the test version of RHINO for MAC. I would like to set up the same button gestures I use AutoCAD because they are so automatic for me. In AutoCAD I have the left button for Click, the Right button for Return, the middle button (scroll wheel button or one of 2 thumb buttons can be used in the case of the Logitech Marathon Mouse) that pops up a OSNAP menu so I can select what I want to snap to and my mouse does not have to move from the work space area in the drawing I am working on to do so. Anyway, I went into Rhino Preferences and cannot figure it out. Thanks for any help you can give me, I am anxious to get going with Rhino!
