Depending on whether the draft grid in a drawing is Cartesian or Polar, the CART PARAMS or POLAR PARAMS menu is displayed when you click Grid Params on the GRID MODIFY menu. Cartesian grid is the default draft grid type.
For a Cartesian grid, the CART PARAMS menu displays these commands:
• X&Y Spacing—Sets the spacing of the grid lines in both the x-direction and y-direction to the same value.
• X Spacing—Sets the x-spacing of the grid lines only.
• Y Spacing—Sets the y-spacing of the grid lines only.
• Angle—Modifies the angle between the screen horizontal and the x-direction grid.
For a Polar grid, the POLAR PARAMS menu displays these commands:
• Ang Spacing—Sets the angular spacing between radial lines. The value you type must divide evenly into 360.
• Num Lines—Sets the number of radial lines to use. The angular spacing is 360 per number of lines.
• Rad Spacing—Modifies the spacing of the circular grid.
• Angle—Modifies the angle between the horizontal and the 0-degree radial line.
