Overview

AP224 is formally known as STEP Part 224: Application Protocol for Mechanical Product Definition for Process Planning Using Machining Features. The standard was published in 1999, updated by a second edition in 2001, and then a third edition issued in 2006 as ISO 10303-224:2006(E).

Programming Notes

The AP224 schema is the same for all editions and is identified by the StplibSchemaType stplib_schema_ap224 enum.

RoseDesign * d;

// all editions "FEATURE_BASED_PROCESS_PLANNING"
stplib_put_schema (d, stplib_schema_ap224);

switch (stplib_get_schema(d)) {
case stplib_schema_ap224:
    // ap224, all editions
}

Deprecated Definitions

AP224 was an early AP, and used naming conventions that later changed. Assignments in AP224 had a "feature_based_pp_" prefix, while newer APs use the "applied_" prefix.

The table below shows the changes. When reading an AP224 file, an entity in the left column is will appear in memory as an instance of the type on the right. When writing a file as AP224, an instance of a type on the right will be written as the type on the left.
