We also have Dimension Tools guides (v 1.9.11) as well as Toolbox Guides.
As always, any mistakes are purely my own. If there's any feedback, I'd love to hear it so we can continue to get better. If there's any questions or if anything isn't clear, I'm more than happy to help--I'd especially like to know if there's a lack of clarity, so that can be improved.
On the DTC YouTube channel, we've also some video guides for Dimension Tools, as well as a full set for Tinker Tools.
