Create and Modify Cavity Feature Example (C#)

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

//-----------------------------------------------------------------------------------------------
// Preconditions:
// 1. Create a new folder and copy install_dir\samples\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.
