This example shows how to create and modify a cavity feature.

'-----------------------------------------------------------------------------------------------
' Preconditions:
' 1. Create a new folder and copy public_documents\tutorial\molds\telephone.sldprt to that
'    folder.
' 2. Click File > New > Part and OK to create a new part document.
'    a. Insert a sketch of a rectangle with a length of 240 mm and width of 350 mm.
'    b. Using the sketch, create a boss extrude feature with a depth of 160 mm.
'    c. Save the part as telephoneMoldBase.sldprt in the folder created in step 1.
' 3. Click File > New > Assembly and OK to create a new assembly document.
'    a. Click telephoneMoldBase in Part/Assembly to Insert in the PropertyManager page.
'    b. Click OK.
'    c. Click Insert Components on the Assembly toolbar, click Browse in
'       Part/Assembly to Insert, click telephone.sldprt located in the folder created in step 1,
'       and click Open.
'    d. Drop telephone.sldprt in the graphics area.
'    e. Click View > Display > Hidden Lines Visible.
'    f. In the FeatureManager design tree, click telephone<1> and click Move Component
'       in the Assembly toolbar.
'    g. Move telephone<1> into the center of telephoneMoldBase<1> and click OK.
'    h. Click File > Save All > Rebuild and save the document (recommended), navigate to the
'       folder created in step 1, type AssemInterim.sldasm in File name, and click Save.
'    i. In the FeatureManager design tree, click telephoneMoldBase<1> and click Edit Component
'       in the Assembly toolbar.
'    j. Click Cavity on the Mold Tools toolbar.
'    k. Click telephone<1> in the FeatureManager design tree for the design component.
'    l. Clear Scale uniformly and set X, Y, and Z to 0, if necessary.
'    m. Click OK to create the cavity feature and close the PropertyManager page.
' 4. Click File > Save All.
' 5. Click File > Close two times.
' 6. Click File > AssemInterim.sldasm.
' 7. Open the Immediate window.
' 8. Run the macro.
'
' Postconditions:
' 1. Accesses Cavity<1> and gets and sets scale-related properties.
' 2. When the macro finishes executing, click File > Close and Save All.
' 3. Open AssemInterim.sldasm, click Yes to roll forward, and click Rebuild to rebuild.
' 4. Expand telephoneMoldBase<1> in the FeatureManager design tree.
' 5. Right-click the Cavity1 feature, click Edit Feature, click OK if a message box displays, and
'    compare the values in the PropertyManager page with the new values shown in the
'    Immediate window.
' 6. Click OK.
' 7. Close File > Close > Save All.
