Hello Again! I'm back to search and learn something new from this unique site. I came from a vacation and was able to talk to my cousin who have been familiar with CAD - (computer aided design). According to her, it is really good to know that the software could help improve the quality of designs. By the way, I'm glad that I have been reading some topics here that I could relate it to her. Great day guys! I'm so excited to start reading and participating again.
