The trend is to hire CADD-literate interns, or to raid other firms for trained CADD staff who may be technically weak. Interns may move through three or four firms in two years, never seeing a project completed, let alone built. In this transitory climate, CADD-proficient staff rarely learn to produce accurate, technically correct design and production drawings. Another option is to hire and train an unskilled employee, but if you do, you'll need to take into account the cost of downtime for training. Don't assume that the drawings your CADD personnel produce are accurate simply because they passed through computer software.
People make mistakes, and with computers the mistakes can be made and repeated more quickly.
Computer-generated dimensions won't be correct, for example, if the drawing parameters are keyed in wrong or if the dimensions are not placed exactly. You can prevent and minimize errors by using quality-control checks and standardized CADD procedures. LLC All Rights Reserved.
