Hello Gerry,
If you could go into a bit more detail here I would greatly appreciate it, as I have never been able to find anything in the help files!
If I type "open" in the search box on the "Search" tab, the only thing close is "Open files modified in AutoCAD", which isn't close.
If I type "open" in the search box on the "Index" tab, it jumps from "Online translations" to "Options". No "open".
When I first started, I needed to draw a line tangent to a circle so I typed "Tangent" in the search box and sixteen topics came up, none told how to do it. It told how to draw circles tangent to lines, and many other combinations, but not a line tangent to a circle. I discovered how to do it at a later date by accident while drawing something else.
Thank You!
