· Click Return tool

· Next, extrude circle to create head (page 7)

· Extrude the Circle

· Click Extrude tool

· Click inside the inner circle

· Click between the two circles to select the second profile

· Enter 4 mm in the Distance edit box

· Click OK to create the extrusion

· Next

· Define new sketch plane

· Project geometry onto sketch plane

· We use projected geometry to create next sketch (page 8)

· Start New Sketch

· Click Sketch tool

· Click Hidden Edge Display tool on Standard toolbar

· Click Projected Geometry tool on 2D Sketch Panel

· Click edge of front face of shaft

· Right-click

· Select Done (page 9)

· Sketch a Polygon

· Click Look At tool

· Click the Projected Circle

· Click the circle center point

· Click a point on edge of projected circle

· Click Done in Polygon dialog box to create polygon

· Tip: Look for Coincident constraint symbol

· Click Show Constraints (not)

· Pause cursor over edge of circle (?)

· Next, fully constrain sketch (page 10)

· Constrain Sketch

· Click arrow beside Constraint tool

· Click Horizontal tool

· Click bottom line of polygon

· Right-click

· Done

· Exit sketch

· Click Return tool

· Or right-click and select Finish Sketch (page 11)

· Create Cut Extrusion

· Press F5 till you return to our isometric view

· Click Shaded Display

· Click Extrude tool on Part Features panel

· Extrude dialog box

· Select hexagonal sketch profile

· Click Cut tool button in Extrude dialog

· Enter 2 mm in Distance edit box

· Click OK to create cut (page 12)

· Save Work Often

· Click Save tool

· File name

· der_002.ipt

· Keep file open

· Next

· Open file of derived part and change number of threads (page 13)

· Modify Parent Part

· Open der_001.ipt

· Select Open from File menu

· Double-click der_001.ipt

· Right-click Coil1 in browser, and then select Edit Feature

· Click Coil Size tab

· Enter 15 in Height field

· Enter 15 in Revolution field

· Click OK to update coil feature

· Click Save on the Inventor Standard toolbar to save the changes to disk (page 14)

· Update Derived Part

· Switch to der_002.ipt window

· Notice

· Derived part der_002.ipt icon has changed to a lightning bolt

· This indicates origin part was modified

· This part does not reflect changes to original part

· Next

· Update derived part

· Break link to original file (page 15)

· Update Derived Part

· Click Update tool

· Part is updated

· Derived part is linked to original

· If no more changes are required

· Sever link

· Making sure changes to original part will not affect derived part (page 16)

· Protect Original File

· To sever link

· Right-click der_001.ipt

· Select Break Link with Base Part

· Icon changes to broken link icon

· Save work

· Tip

· If we select Suppress Link with Base Part instead link can be restored later (page 17)

· Restore and Close Parent File

· Switch to der_001.ipt window

· Right-click Coil1 in browser Select Edit Feature

· Click Coil Size tab

· Height field

· Enter 10

· Revolution field

· Enter 10

· Click OK to update the coil feature

· Click Save

· Click Close

· We can

· Explore design alternatives with derived parts

· Build library of parts

· Click Close from the File menu (page 18)

· Summary

· In Empty Part

· We learned

· Use an existing part as the base feature of a new derived part

· Add features to a derived part

· Modify the parent part and update the derived part

· Break the link between a derived part and its parent part
