Howdy gurus, fellow novices, and all in between --

1) If I send someone a dwg file that I created using a line style that they do not have loaded ... what happens? Are the lines of styles not loaded displayed correctly? Are they shown in a default style? If defaulted ... are there any warning messages stating which line styles are needed to see the dwg as intended? Perhaps DraftSight automatically attempts to load the missing styles?

2) As a CAD novice, once the command line power became apparent ... it felt like a door had been opened. Many of the commands are too specialized for me yet to utilize until my skills improve; however, as I stumble along, my favorite 3 command line inputs are: "a" (add), "r" (remove), and "fence". All of these involve selecting entities and have greatly sped up that part of the drawing task for me.

Please tell me which commands you use the most often. A top 5 or top 10 list would be great, as this will allow me to focus on a smaller learning target and be less overwhelmed by the multitude of options.

Thanks.
