I am trying to teach myself AC LT. I am retired and do woodworking as a hobby. My usage of AC is to 'design' the various things I want to make andthen have 'she who must be obeyed' check out the measurements etc. It is another activity to keep me from slipping into senility. There are those who say I have already slipped. I have an AC LT manual that is of some help. I also use ACs Help but usually find it confusing as I do not have enough of a background to understand it. So I have posted my questions here and also at http://discussion.autodesk.com/forums and have received a tremendous amount of help. For that I would like to thank those of who have responded to my past inquiries and ask you to be on the alert for my future ones. Thanks again.
