I just received a 3dconnexion spacemouse (the basic wireless one). I installed the latest driver, under drafsight it works without problem, under solidworks 2015 SP3, the driver appears in the add-ons, on the other hand despite that I activate it impossible to use the mouse. When reading the document provided by 3Dconnexion a drop-down menu should also appear between "tool" and "window" of the toolbar, but the latter is not present.
If anyone has ever been confronted with this problem, please enlighten me.
First, check if the "3Dcontrol" add-in launches when SW starts. As visible as an attachment. To do this, "Tools" then "Complements... ".
Then check that the driver launches when windows starts. To do this, at the bottom of the start menu, type the command "msconfig" and then [Enter]. A window appears. Use the startup tab to see the list of programs that launch when windows starts. In it you should see an item "3Dconnexion, Inc 3DxService". Verifies that this item is selected.
