Industrial Drafting (Computer Aided Design)

All topics relate to industry and include things such as detail and assembly drawing, development of mechanisms, machine frames along with electrical and electronic and sheet metal drawing. Students will use the current versions of autocad, solidworks and autodesk inventor. 

Our program enables students to acquire the knowledge, skills, and attitudes required to produce drawings quickly and accurately, using a computerized workstation.
