About the group:
Design online is created by a group of engineers concerned with providing designers with basic courses in their working field. Since any designer through his career should master one or more software, we believe that a real designer should be a professional software user. We believe that professionalism cannot be achieved by simply learning how to use a software, but by supporting it by basic science and practical career life knowledge as well.
Who should care?
Since we believe that any engineer can be professional designer once s/he decides, our courses have no prerequisites. We start with you from the point where you are standing to the point where you should be. So, everyone can participate. This is our belief. Be professional. Be unique.
