As you know, I am trying to write a book on DoubleCAD. In order to do this I have been trying to teach myself the various functions of DoubleCAD that I am not too familiar with or that are different than how the same or similar functions work in AutoCAD. I have devoted the first 6 chapters of the book (almost 200 pages) to describe the use of DoubleCAD's basic functions. Now I have begun writing the chapters dealing with more advanced intermediate type of functions. These Webinars should greatly help me to learn the more advanced areas of DoubleCAD. However, I have a full time job and will not be able to attend many of live Webinars. You say that they will be recorded so that they can be viewed later. That would be a great help to me and much appreciated.
Maybe a future Webinar could be making parimetric symbols. Using scripts would be in the advanced section of the book, but my knowledge in this area is very limited so any Webinars on this would be very useful.
Another Webinar could maybe deal with how to use the Library. I have already dealt with this in the book as a basic function but it was a frustrating undertaking and I found the help files confusing. As the symbol library is a very important function of any CAD program I put a great deal of time on this subject, first trying to understand how the DoubleCAD symbol library works, and then writing about it so that it will be clear to others. A Webinar on this, I feel, would be very useful to almost anyone using the program.
