Comparing two models

You may have two models of the same component and want to see the differences between them.

  1. Open the models you want to compare.

    Suppose we have the following two models.

    — Model_1

    — Model_2

  2. Click the graphics window of the model in which you want to display the differences. This makes the graphics window active.

    In our example, we made Model_1 the active model.

  3. Select Visualisation tab > Model panel > Compare.
  4. Use the Model Compare dialog to complete the comparison.

Use this dialog to compare models.

Use the following options to control the comparison:

Primary — Select the model in which the differences are to be shown. When the dialog is first displayed, the Primary selection is the model of the active graphics window. You can change the primary selection by selecting the Primary option and clicking another graphics window. The icon indicates that a primary model is selected.

Secondary — Select the model to compare against the Primary selection. To select the second model click the Secondary option and click in the graphics window of the model you want to compare. The changes to a .

Surface trimming comparison — Choose how to compare surfaces with trim boundaries and p-curves. Select:

OK — Compares the two models. All objects, which are in the primary model and not in the secondary model, are highlighted as selected in the primary model.

Note: Objects in the secondary model but not the primary model, are not shown. To show these objects, swap the secondary model with the primary model.
Warning: Models are compared on the basis of positional information (XYZ coordinates) only; differences, such as in tangent direction, colour and level, are not identified. This command can be a useful tool to aid comparison of models, but you must use it with care and check manually for small differences that the command may not identify.
