Creating/Modifying Coordinate Dimensions

This task will show you how to automatically create coordinate dimensions on elements. Coordinate dimensions allow you to define the coordinates of a point relative to X and Y axes.

Open the PointSketch.CATDrawing document.

1. Click the Coordinate Dimension icon

from the Dimensioning toolbar (Dimensions subtoolbar).

2. You can choose between creating generated geometry (3D) coordinates dimensions or sketched (2D) geometry coordinates dimensions.

Two icons appear in the Tools toolbar after clicking the command icon , one for the creation of 2D (x, y) coordinates dimensions and one for 3D (x, y, z) coordinates dimensions .

These icons appear only if you have selected elements from 3D.

Select the 3D (x, y) icon

in the tools box.

3. Select the element to be applied coordinates dimensions.

4. Click the free space.

The Coordinate dimension is automatically created, without any preview.

5. Click the Coordinate dimension to modify the dimension position.

The selected dimension is highlighted and the anchor point appears in yellow.

6. Drag the dimension to a new position.

	Coordinates are relative to absolute axis system except for view created selecting a 3D local axis system.
	The yellow anchor point is associative and is linked to the element you dimensioned.
	Text, dimension and graphic Properties Toolbars settings are taken into account during creation.
	All settings defined in Tools->Option->Mechanical Design->Drafting (dimension and manipulators tabs) are taken into account during creation.
	You can select a set of elements (step 3.) to create coordinates dimensions in one shot.
