To add a polar grid, select Polar as the type.

Arc

Select the properties of grid lines parallel to the arc.

• Number of lines - Enter the number of grid lines parallel to the arc.
• Radius + Spacing - Enter the radius of the 1st arc (r) and the modular spacing (s) of the other arcs in millimeters in the metric system, inches in the imperial system. For example, 10000+4000, where the radius of the 1st arc = 10000 and the modular spacing = 4000.
• Line extension (°) - Enter the length of the line extension (α) outside the grid in degrees.

Prevent Delete

You can select the property Prevent Delete for a grid. This prevents accidental deletion of the grid. To delete a grid, first open the grid properties and clear the Prevent Delete option.

Location

Origin

By default, the grid is added to the origin point. If necessary, you can enter the coordinates of the grid reference point in the X, Y, and Z fields. To click the position of the reference point, select Click.

Rotation

If necessary, enter the rotation of the grid in the xy plane in degrees. A positive value rotates counter-clockwise, a negative value rotates clockwise.

Click

To click the location and rotation of the grid in a drawing or model, select Click. Select the location and direction:

• The location of the lower left corner of a rectangular grid and the direction of the horizontal grid lines.
• The intersection point of the first radial grid line and the first grid line parallel to the arc, and the direction of the first radial grid line.

Plot

Lines

Select the line drawing properties Line type, Line width, Scale, and Color. To restore the default system properties, click Default. The default properties are set in the system settings with the line name GRID.LINE.

Line Setup

Labels

Enter the Height of the grid line labels and select the Color. To restore the default system properties, click Default. The default properties are set in the system settings with the the text name GRID.LABEL.

Text Setup

By default, the grid line label is inside a circular frame. To remove the frame, clear the Add frame option. Enter the factor that determines the frame size in the Frame size field. The factor is used to multiply the height of the label text.

Select the frame drawing properties Line type, Line width, Scale, and Color. To restore the default system properties, click Default. The default properties are set in the system settings with the line name GRID.LABELLINE.
