Most programs starts a new tab or something similar when opening a new document while the program is already running, but if you open a grasshopper-file by double clicking it in file explorer a whole new Rhino starts. Is there a way to change this setting?
Grasshopper has the functionality to have multiple scrips open at the same time, so I cant see why this isn’t possible.
Perhaps I am missing something, but I frequently open GH files simply by double-clicking them. Doing this starts Rhino, and then GH opens and and loads the selected GH file. I believe this is a standard function of Windows that happens as a result of file association: if you right-click on a GH file you get a list of options, one of which is Open with…
Selecting this gives you a dialog that lets you specify the program you want to use to open this type of file. That dialog has a check box that lets you always use the program to open the GH file type. So just specify Rhino. From then on double-clicking a GH file will cause Rhino to start, open GH, and load the file.
I do that all the time by drag & drop from my file manager onto the GH window. I grant you it’s quite easy for me because I have 2 monitors, but if you get used to using Alt-Tab it’s pretty easy to do with only one screen.
