Nice course practice using the Autocad software. Very good course the only bad thing the sound quality is very low. Had a hard time hearing and the text doesn't help much because it is not proof read. Learn to use the scale tool in a different way. Interesting to use the inches and foot, I use more the metric system. The only doubts I had when when printing that some colors still appear in color even thought I used the monochrome and assign how the colors behave.
