MET 306 Activity 4 Introduction to ISDX Interactive Surface Design Extension Release WILDFIRE 40 Level 7 Continued The goal ofthis exercise is to be able to model the plastic cover shown above The coverwill actually be hinged on the upper back edge and the rounded area in the front is to satisfy the industrial designers requirements The cross section is shown for clarity An enlarged view of the
