Delete Instances and Dimensions in Variable Pattern Feature Example (C#)

This example shows how to:

  • delete instances in a variable pattern feature.
  • add and delete dimensions in the pattern table of a variable pattern feature.
//---------------------------------------------------------
// Preconditions:
// 1. Verify that the part exists.
// 2. Open the Immediate window.
//
// Postconditions:
// 1. Opens the part and selects the variable pattern feature.
// 2. Accesses the variable pattern feature.
// 3. Deletes the last and fourth instance from the pattern table
//    and pattern.
// 4. Gets the number and names of the controlling dimensions.
// 5. Selects and adds two dimensions to the pattern table and
//    deletes the second dimension from the pattern table.
// 6. Rolls forward the modified variable pattern feature.
// 7. Examine the graphics area and Immediate window.
//
// NOTE: Because the part is used elsewhere, do not save changes.
