Title: ModelCHECK Date: 8/22/01 Objective: At the end of this tutorial, you will know how ModelCHECK:

• can help you adhere to your company’s standards (Parameters, Layers, etc) • facilitates Reuse of Models • can assist with Problem Resolution, Education, and Online Advice • can monitor improvement

Overview:

ModelCHECK evaluates Pro/ENGINEER parts, assemblies, and drawings to ensure that they adhere to a company's modeling standards and best practices. If an exception to these conventions is detected, users are notified of the inconsistency, given tools to identify the problem within the solid model, and can often make a correction

Title: ModelCHECK Date: 8/22/01 automatically from the familiar web-based ModelCHECK interface. ModelCHECK facilitates the work of design team engineers by letting users create superior models that are well suited for reuse in downstream applications. Facilitating Reuse of Models As companies continue to embed Pro/ENGINEER into their design process, reusing the model becomes increasingly important. To facilitate reuse, models have to be created in accordance with common and accepted design philosophies and must contain all necessary information. However, users are often unaware of the design standards, or the company has difficulty enforcing them. ModelCHECK helps designers use correct modeling practices by letting them constantly monitor the Pro/ENGINEER model as design features are added, much as they would use a spell checker for a word processing application. In this manner, variations from accepted practices can be detected and corrected early in the design process, before they affect downstream users of the model and incur additional costs. Detecting Existing Designs As the volume of models being created and stored in databases continues to grow, the opportunity to reuse existing designs increases. The problem is that with an increased number of models stored, it becomes progressively more difficult to identify similar designs. Often previously designed and released models are re-created from scratch simply because the user had no ability to determine if the model already existed somewhere in the database. ModelCHECK introduces powerful new patent pending Shape Indexing™ technology that enables rapid detection of existing designs. While a user is building a model, ModelCHECK is constantly scanning the model's geometry to determine if a model with similar shape has been previously created. As soon as a similar model is detected, ModelCHECK informs the user of this opportunity and displays to them the degree of similarity between the two models and from where the existing model can be retrieved. Problem Resolution, Education, and Online Advice The first step in guaranteeing the quality of any finished solid model is making sure users are aware of information missing in their model. ModelCHECK offers tools beyond simple notification. It will not only identify the feature in question but also actually make corrections to the model. In addition, users can easily access online help pages specific to the problem identified. This type of immediate feedback will advance user knowledge of Pro/ENGINEER modeling practices and help avoid the same types of mistakes in the future. Automated Tracking of Model Quality As ModelCHECK is run on Pro/ENGINEER models, a database is created to track the types of problems found and their frequency. Tools provided with ModelCHECK sort and graph this data for trend analysis. The result is an engineering management organization that better understands the training needs and challenges of their Pro/ENGINEER users.

Title: ModelCHECK Date: 8/22/01 Using ModelCHECK: Much of the effort in implementing ModelCHECK is done by the system administrator. He or she is responsible for configuring the checks to adhere to your company’s standards. Once the configuration is established, the use of ModelCHECK becomes part of the Pro/ENGINEER users everyday workflow. The reports are easy to read and many of the problems found in models can be fixed with a single button pick from the report window. ModelCHECK runs in four ways:

• Interactively (as shown below) • When the model is regenerated • When the model is saved • In batch mode

Title: ModelCHECK Date: 8/22/01 The ModelCHECK report displays the items in the model that have failed during the check. A sample check is shown below.

This section gives information about the model, how ModelCHECK was run and which configuration files were used

Errors and Warnings are reported

Selecting Report will reformat the window as shown below to allow corrective action

Shows indented Bill of Material with the number of errors and warnings for each part listed. A sample window is pictured below. Page 8

Compiles total list of errors for the assembly, Tells how many parts fail each check. A sample window is pictured below. Page 7

Window shown when “report” is chosen in the initial summary window

This section gives information about the model, how ModelCHECK was run and which configuration files were used

The summary tab shows all warnings and errors from all of the checks. It does not list checks that have passed

Each tab will list all relevant checks run, with a status of ok, error or warning

For many checks (like the parameter check shown) selecting on the red buttons will correct the problem detected. Others may need to be corrected manually

6


Window shown when “Assembly BOM failed checks” is chosen in the initial summary window

Results are listed for all checks that have failed in the assembly or any of its’ models. The number of models which have the particular failure are listed.

7


Window shown when “Assembly Bill of Material” is chosen in the initial summary window

An indented BOM is shown with the tally of errors and warnings for each component

Users are able to navigate to the reports for a given component through this window and where appropriate, fix the errors

Some of the general check capabilities are shown below. These are taken from the list of all checks which follows on page 10. Conformance to Standards
