36. iFeatures Table-Driven iFeatures –Open the.ide file in Autodesk Inventor –iFeature Author Table iFeatures behave similar to iParts –Main difference: No File Name, Display Style or Material column designations

37. iFeatures Table-Driven iFeatures –Inserting Same as inserting typical iFeatures Key parameters are a drop-down list Custom parameters are specified in the dialog box

38. Exercise 9-4 Creating and Placing iFeatures

39. Design View Representations Save configurations that show the assembly in different states, stores the following –Component visibility (visible or not visible) –Component selection status (enabled or not enabled) –Color settings and style characteristics applied in the assembly –Zoom magnification –Viewing angle

40. Create New Design View Representation Make Active Rename Lock Public vs. Private Design Views Design View Representations

41. New Design View Representation Make Active – check mark Lock – view changes are not reflected in locked Design View Representation Design View Representations

42. Set Design View when placing an assembly file –Options button –Select Design View Design View Representations

43. Make Design View in a subassembly active –Select from list Design View Representations

44. Same as a Public Design View Representation buts creates an IDV file Should accompany assembly file Private Design View Representations
