Analyzing Generated Dimensions

Before you begin, make sure you customized the following settings:

Dimension generation:
Go to Tools->Options->Mechanical Design->Drafting, and click on the Generation tab. Check the Analysis after generation option. This automatically launches the generated dimensions analysis after dimension generation.

This task will show you how to analyze generated dimensions via the Generated Dimension Analysis dialog box.

Open the GenDrafting_front_view.CATDrawing and the GenDrafting_part.CATPart documents.

Tile your windows horizontally to view both your drawing and the related part. To do this, select Window -> Tile Horizontally from the menu bar.

1. Click the Generating Dimensions icon

from the Generation toolbar (Dimension Generation subtoolbar).

The dimensions are generated on the view. You can select a dimension in the drawing to highlight the corresponding constraint in the 3D, and vice-versa.

The Generated Dimension Analysis dialog box is automatically displayed.

The Generated Dimension Analysis dialog box displays the number of constraints available in the 3D, as well as the number of dimensions generated on the drawing, for each part or product in the drawing (in this case, there is only one part). You can use the options in this dialog box to highlight the dimensions in the drafting sheet as well as the associated 3D constraints you can visualize in your Part or Product document.

Let's describe the dialog box more precisely:

Constraint Analysis in 3D

These options let you highlight specific constraints on the 3D part.

	`Generated constraints`: highlights all the constraints which are associated with the dimensions generated on the drawing.
	`Other constraints`: highlights all the constraints for which dimensions have not been generated on the drawing.
	`Excluded constraints`: highlights all the constraints which have not been taken into account during the dimension generation (this can be because you previously excluded them using the Not Generated icon when performing a step by step generation, or because you removed a generated dimension from the drawing).

Dimension Analysis in 2D

These options let you highlight specific dimensions on the drawing.

	`New Generated Dimensions`: highlights the dimensions which were generated during the latest dimension generation (this is useful if you generate dimensions several times).
	`Generated Dimensions`: highlights all the generated dimensions.
	`Other Dimensions`: highlights the dimensions created manually via the Interactive Drafting workbench.

2. Check the Generated constraintsand Generated Dimensions options. The generated dimensions are highlighted on the drawing, and the constraints associated with the generated dimensions are highlighted on the 3D part.

2. Click OK to close the dialog box.

	The `Analysis after generation` option automatically displays the Generated Dimension Analysis dialog box (after dimension generation), each time you generate dimensions either automatically (Generating Dimensions icon ) or semi-automatically (Generating Dimensions Step by Step icon ).
	By default, the `Analysis after generation` option in `Tools->Options`is checked, and the Generated Dimension Analysis dialog box is automatically displayed at the end of dimension generation. You can deactivate this default by unselecting the `Analysis after generation` option.
	You can also launch an analysis explicitly when needed. To do this, go to `Tools->Dimension Generation->Analysis`. The Generated Dimension Analysis dialog box will be displayed immediately.
