Creating a shortcut for changing the solidify thickness

Question

I would like to create a shortcut for changing a solidify modifiers thickness much like changing the amount of subdivision with Ctrl + number or hitting the S key and typing the number for scaling. Is there an easy way to do that?

Answer 1

This can be easily done with python.

1. Get the script

Copy the script into blender's text editor and save it as "solidify_set.py" (NOT "solidify_set.py.txt").

OR

Download from github (see the comments for more info).

2. Install it as an add-on

(make sure to click the all category and the community supported level)

3. Add the hotkeys that you would like

It should be added in the "3D View > Object Mode" section where the subdivision set operator is.

Click Add New, then enter "solidify_raise", then enter your hotkey (and select any key modifiers you want...shift, ctrl, etc.). Click Add New, then enter "solidify_lower", then enter your hotkey (and select any key modifiers you want...shift, ctrl, etc.). You can click on the amount setting to set the amount it shifts. Clicking on the restore button, restores your hotkeys to the way they were before. Finally, don't forget to save user prefs with Save User Settings :-)
