With the CAD Like Transform Addon we can precisely define how we want to snap during a grab, scale or rotation. Snap from the center of a face, center from edge? Or scale an object where you can define to scale from where to where as if you set temporally the origin point to a vertex? That all is possible, and with ease with this addon. And that’s just the basics.
What else I like about the addon is that it doesn’t occupy the N-Panel. Instead it shows up as a tool in the Toolbar. Another benefit of this is that any shortcut the addon is using, it’s not interfering with the rest of Blender’s shortcuts. This because the shortcuts get only active when you activate the tool in the tool-shelf (T-Panel)
In short this is the very basics of how the addon works (Add two cubes in the scene first to practise):
Those are the basics, and I suggest to play around with that until you get that into the muscle memory. But there is more. One of the first things you want to know is that during a Grab, Rotate of Scale you can clear the snapping mode by pressing space bar and define again what the snapping mode is. You can also combine snapping modes.
Another thing that is handy, is that you can always move around the object in your viewport with the middle mouse button. You can do this during the operations

You can get the CAD like transform on Gumroad. It’s free, but the addon is so well done, and the the developer did an awesome job, so if you consider to pay anything you like the developer will be encouraged to continue his activities.
You can also read more about the addon on Blender Artists. Interesting to note is that the addon is made by Stephen Leger who is the developer of the Archipack addon.
