# Creating a Hole Dimension Table

This task will show you how to create a hole and center line dimension table (containing diameter and center coordinates).
Open the alesage.CATDrawing document.
1. Select one or more holes and center lines (only center lines not associated with a hole) in the drawing.

 Do not select arcs of circles, as it is impossible to include them in a hole and center line dimension table. Hole and center line dimension tables cannot be associative. Selecting an element in the drawing does not make the table associative to this element.
2. Click Hole Dimension Table in the Dimensioning toolbar.

The Axis System and Table Parameters dialog box is displayed.

This dialog box contains the following options:

• Axis system: Indicate the holes coordinates 2D reference axis system. In this example, click on  the view origin (you can also select two lines or click anywhere in the drawing, or enter the origin coordinate).

Two reference axis appear:

You can rotate or flip the axis using the Flip horizontally and Flip vertically icons and choose to represent the axis system by checking the Create representation box.

• Title: Type the table title.

• Columns:

• Choose a label (A, B, C... or 1, 2, 3...). If you want column numbering to start with values other than A or 1, click the icon and specify the start value.

• Select and name the column to display.

• Table format:

• Select the Transpose table check box to invert columns and rows.

• Select the Sort table content  check box to sort the table elements.

• Select the Split table  check box to split the table into several tables. For more information on splitting tables, see Creating/Modifying a table.

3. Choose 2D reference axis system for the axis system from the associated drop-down list.

4. Type the table name in the Title field.

5. Select Label: A, B, C from the Column drop-down list (you can also choose the Index naming mode) to give a label to the selected points in the drawing.

6. Select the X, Y and Diameter  check boxes to have four columns corresponding to the hole labels and to the Cartesian coordinates. Then enter a title for each column.

7. Select the Transpose table check box to invert columns and rows in the table.

8. Select the Sort table content check box and then click the [...] icon  to define the sorting parameters.
The Sort dialog box is displayed.

9. To sort the table by descending X coordinates, choose X in the Sort by combo box, and select Descending. Then, click Close.

 At this point, if you want to change the precision value, you may do so using the Numerical Properties toolbar. Note that once you validate the creation of the points coordinate table (by clicking OK in the Axis System and Table Parameters dialog box), you will no longer be able to edit these dimension properties. Also note that you can not edit Coordinates Table precision value through style customization.
10. Click OK in the Axis System and Table Parameters dialog box to validate your settings and click in the drawing to define the location of the table. The table is generated.
