I previously mentioned [here] that the circle command with the TTT (tangent, tangent, tangent) option was only available with use of the ribbon. I am happy to report that there is a way around this in the form of an undocumented command called AI_CIRCTAN. There seems to be a bunch of commands that have that “AI_” prefix. I haven’t fiddled around with them to see if there are any gems. But when I do find some, I will post them here.
You can use this command and associate it with a button & macro and add it to a toolbar if you think that you will make use of it a lot. Again, this command is a deafult command with its own button in the ribbon found in the Home tab > Draw panel > Circle tool pulldown – Tan, Tan, Tan
Here’s how to use it:
- AI_CIRCTAN <enter> to start
- Select the 3 objects that you want the circle to be tangent to
