Description

The ap203check, ap209check and ap214check tools rapidly check data files against the local rules (WHERE clauses) and global rules (RULEs) defined in the AP203, AP209 and AP214 EXPRESS schemas. The tool also checks for the presence of all required (non-OPTIONAL) attribute values in the data file.

The ap203check, ap209check and ap214check tools are faster than apconform, but are specific to a particular schema. Whereas the apconform tool utilizes a general EXPRESS interpreter, ap2XXcheck tools use custom C++ optimized for speed with techniques such as pre-computing reverse (USEDIN/INVERSE) references between entity instances.

Command Line 

ap203check [options] <data-file>
ap209check [options] <data-file>
ap214check [options] <data-file>

The options accepted by the checkers are:

Print this list of options and exit.

Windows Control Panel

The AP203 Checker Windows control panel is shown in the figure below. Run this by selecting AP203 Checker, AP209 Checker, or AP214 Checker from the Start Menu. The following sections describe the fields and setting on this control panel and show how to perform various tasks with the checker.

AP203 Checker Control Panel
AP203 Checker Control Panel

At the top of the AP203 Checker control panel is a text field for the STEP files that you would like to check. You can open the file dialog using Ctrl+O or the [...] button to the right. You can also drag and drop files from the Windows Explorer. Click the Check button to start checking.

Example

As an example, we test a file to see if it meets the AP203 schema constraints. The example file is an assembly of parts forming a doghouse. It is a modified copy of the file doghouse.stp on our web site translation service. It has been modified so that the geometric context entity instance specifies 2-dimensionality (while the geometry remains 3-dimensional) and so that one of the edge_loop instances does not meet a head-to-tail constraint.
