DEFINE

Purpose:

To redefine the size and origin of the orthogonal grid in the current drawing.

Instructions:

In the View menu, click Grid, then Define.

In a dialog box showing up, the user is prompted to key in the grid size, that means, the distance between two adjacent grid points along the x- and y-axis (the current size is proposed by the system). A single value keyed is accepted and will be interpreted as the distance along both the x- and y-axis.

Next, the user is prompted to key in the x- and y-coordinate of the grid origin (the current origin is proposed by the system).

Options:

There are alternatives for defining both the grid size and the grid origin.

When you are prompted to key in the grid size, click Options and a multiple choice dialog appears:

1. Standard

2. Key in

3. Two positions

The Standard grid size is controlled by the Default Keyword GRID_SIZE, while defining by Two positions means that you are expected to supply two points in the drawing giving the diagonal of one square of the grid.

When you are prompted to key in the grid origin, click Options and a multiple choice dialog appears:

1. Standard

2. Key in

3. One position

The Standard grid origin is controlled by the Default Keyword GRID_ORIGIN, while defining by One position means that you are expected to supply a point in the drawing giving the origin.

Result:

The grid belonging the current drawing is redefined according to the user.
