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 front is shown below 11132008 Page 1 of9 MET 306 Activity 4 Begin by creating a solid protrusion shown below 11132008 Page 2 of 9 M ET 306 Activity 4 Create a datum curves on DTM1 using the following

curves Start by creating a style feature Insert Style Notice the following items39 1 There is a default active datum plane highlighted the grid 2 A new menu appears vertically to the right above the datum menu These are style options Select the fth box down Create COS s by projecting curves onto surfaces Follow the menu options to Select the curves to drop datum curve on DTM2 Select surfaces on

create a new curve At the top of the graphics screen select S ing Snap to turn on the snapping function Select Planer in the dashboard and draw a straight line as show on the r39ght We now need to

shown below Turn off the Snap then selecting the point and dragging it This is best done in the right side view We now need to define tangencies Select the lower end point Move the cursor overthe orange tangent line that extends from the end point of the curve right click the mouse and select Surface Tangent You can drag the tangent line to influence how this constraint modifies the overall curve Once you have set a tangent you can select this point and the Constraints and Properties of this will appear as shown below Now set the Length to 9 and define the tangency of the other end point
