Mouse Trouble

....of the CAD kind. The wheel as seen without the mouse cover. The importance of the red "button" used when pressing the wheel down in order to spin or orbit objects in the 3D CAD world can often be overlooked. Rolling the wheel will zoom you in and out of the workspace. This image was taken for an A-level student working on such mechanisms.
Talking of CAD work, we've been working/try out a new revolutionary piece of software called Onshape. This software does not need to be downloaded as it is all done online, live. This does mean that both Apple users and Windows folk can use it without any downloading issues. So far so good, but I still prefer Solidworks. A few more weeks will allow me to make a proper judgement on it. The pupils love it so far.
