Using the Model Navigation Tool . Finding Information About Features Info Feature . Finding Information About Objects Engineering Changes You must be able to determine how a model was build, and then determine the best approach for editing it. Editing the model is earlier, once the construction method is determined. Model interrogation Techniques Info: Info Object Info Feature Info Expression Note: In modeling, Naming features’ primary expressions. Model Navigation Tool Toolbox MNT Edit: Edit Feature Playback Edit Feature Suppress / Unsuppress Feature Reordering Feature Usage: To edit a model by changing the order of Feature ( Timestamp ) Solves “ Update Fail” during perform model change. Suppress / Unsuppress Features This option temporarily remove selected features form a target body Usage: Reduces the size of your model, which make it easier to work on Speeds up creation, object selection, edit and display time Removes non-critical features from your model such as holes / blends for analysis work Solves “ Update Fail” during perform model change. Methods: Edit Feature Suppress / Unsuppress Features Edit Feature Suppress / Unsuppress Feature by expression Pn = 0 / 1 Unsuppress Suppress Note:This option make one model may have multiple structure configuration Thickness = thk Thickness thk Performing Engineering Change Method:
