# How to modify gears add-on in Blender

I'm very new to Blender and have a question that I hope someone can help me with. I am interested in using this gears addon. I have installed the add-on into my version of Blender 2.76b (running on Ubuntu 14.04) from the py script but whatever I try and read I cannot find where to edit the gears (adjust radius, number of teeth etc...).

I'm very confused and hope someone can shine a light on my problem. Many thanks,

• To elaborate on @MrZak's comment... press T in the 3D view to enable the left-hand toolbar, and look at the bottom. You may have to click the little "+" icon at the bottom to make it visible. – John-Paul Gignac Feb 1 '16 at 23:22
• You should always try to look for the add-on wiki pages like this one wiki.blender.org/index.php/Extensions:2.6/Py/Scripts/Add_Mesh/…. Usually it's well documented. – hawkenfox Feb 2 '16 at 5:00
• Thank you for your comments but I have looked at the wiki page you mention and I simply cannot see anywhere the interface for editing the gears that it mentions. I think it must be missing. If I use the last operator menu and select gear, I still cannot see any edit tools in the tool bar (although there is a title 'gear' that appears but below is all empty. – JulianJ Feb 2 '16 at 9:34
• If the operator properties are not visible at the bottom of your toolshelf region then there will be a little + at the bottom that will bring it back. You can also press F6 to show the operator properties in a floating panel. – sambler Feb 2 '16 at 9:57
