Windows TIP: Quickly Open Additional Rhino Program Session

Hi All. In Windows 7 (And probably Win10 too) if you need to quickly open an additional Rhino program session
i.e. to open a 2nd model:
Move the mouse pointer down to the windows taskbar and middle click on the current running rhino toolbar/icon.
An additional rhino program will startup immediately which you can use to open a 2nd, 3rd etc. model.
This tip works for some other programs too.
Useful for Windows Explorer too to open multiple windows without going to desktop or start menu.
Also, Someone else on the forum posted a tip to use:_Run Rhino.exe
from the command line, which does the same job. Michael VS


That’s a great tip. Thanks.

If you’re in Windows 8 or 10, then you can go the start screen [Windows Key] and SHIFT-click on the Rhino icon.

Well, if your start screen looks like the following (Win8), you can just hit the Windows key and click on the Rhino icon.


I made a button, right click start another instance of Rhino left to export part of the design to a temp file and start Rhino with that.

Right Button
_Run “C:\Program Files\Rhinoceros 5 (64-bit)\System\Rhino.exe”

Left Button.
_Run “C:\Program Files\Rhinoceros 5 (64-bit)\System\Rhino.exe c:\temp\temp.3dm”

Or this:

import rhinoscriptsyntax as rs

def OpenRhino():
    message = rs.MessageBox("Are you sure you want to open another session?", 4 + 32 + 256, "Rhinoceros 5.0")
    if message == 6:
        rs.Command("Run rhino.exe")
        print "Please wait while a new Rhino session loads...."
