Working with Multiple Parts in an Assembly

Reusing Your Existing Design

The shape of the lower halfshell is nearly identical to the upper clamp. Rather than designing the lower

halfshell from scratch, with Autodesk Inventor you can derive the design of the lower halfshell from the upper

clamp.

Since you are deriving the design from another part, you do not need to use the default sketch that was

automatically defined when you created this part.

• To finish the existing sketch, in the graphics window, right-click

and then choose Finish Sketch.

To derive the lower halfshell from the existing design of the upper

clamp:

1. On the Panel bar, click the Derived Component tool.

2. In the Open dialog box, select Clamp_top.ipt, and then click

Open.

The derived part is now positioned directly over the upper clamp.

3. To correctly position the derived part, on the Derived Part dialog

box, select the Mirror part check box, and then click OK.

Breaking Shared Part Definitions

The new lower halfshell is now derived directly from the upper clamp design.

One major benefit of a derived design is that when the parent (base part)

changes, the derived parts also change to maintain consistency. However, as we

continue with this design, we want the two clamps to differ. To do this, we can

simply sever the link between the derived part and the base part.

•In the Browser, under Clamp_A:1, right-click Clamp_top.ipt (second item

from the bottom) and then choose Break Link with Base Part.

You can now make changes to the base part without affecting the derived part.
