Add Components Example (C#)

This example shows how to add multiple components to an assembly.

//---------------------------------------------------------------------------
// Preconditions:
// 1. Create a new part document.
//    a. Extrude a rectangular block and cut-extrude a diagonal section

//       off one face of the block.
//    b. Click Insert > Reference Geometry > Coordinate System.
//    c. Select a corner of the block for the origin of

//       the new coordinate system.
//    d. Select an edge for the Z axis of the coordinate system.
//    e. Click the green check mark to save the coordinate system.
//        Coordinate System1 appears in the FeatureManager design tree.
//    f. Save and minimize the part.
// 2. Replace <component_name> in the code with the full path name

//    of the new part.
// 3. Create a new assembly document.
//    a. Create a line segment sketch originating at some distance

//       from the default origin of the assembly document.
//    b. Click Insert > Reference Geometry > Coordinate System.
//    c. Select one end point of the line segment for the origin of

//       the new coordinate system.
//    d. Select the line segment for the X axis of the coordinate system.
//    e. Click the green check mark to save the coordinate system.
//       Coordinate System1 appears in the FeatureManager design tree.
//    f. Right-click on Coordinate System1 in the FeatureManager design tree,

//       select Feature Properties, and rename the coordinate system

//       and its description to differ from Coordinate System1.
//    g. Save the assembly and keep it open.
// 4. Change the namespace to match your project's name.
//
// Postconditions:
// Component part is inserted into the assembly such that
// the part's Coordinate System1 is coincident (no translation or rotation)
// with the assembly's default (not user-defined) coordinate system.
//
