:Draw point: After clicking the button with the mouse, click OK at any point in the
interface to draw a point
:Straight line: after the mouse click on the button, click on any point in the interface
to determine the starting point, the second click to determine the distance between the
starting point and the end point, and measure the length of the straight line (after drawing
the line, and then click the mouse at the appropriate location, the length of the line will be
displayed)
:Crosshairs: After the mouse clicks on the button, the crosshairs are displayed in
the interface after (and coordinates are shown), click again, and repeat the operation
:Parallel lines: After clicking the button with the mouse, click on any point in the
interface to determine the starting point, the second click to determine the straight line,
the third click to determine the position of the parallel line, and measure the distance
between the two parallel lines
:Folded line: After mouse click on the button, click on any point in the interface to
determine the starting point, and click a second time to determine the distance between
the starting point and the end point and turn it into a new straight line starting point...
Measurement is displayed as total length
:Curve: after the mouse clicks on the button, click on any point in the interface to
determine the starting point, the mouse passes through the path for the length, the
second click to determine the end point, measure the length of the drawn line
:Vertical line: after the mouse click on the button, click on any point in the interface
to determine the starting point, the second click to determine the straight line, the third
click to determine the vertical distance from the line, measuring the length of the vertical
line
:Rectangle: After clicking the button with the mouse, click at any point in the
interface to determine the right angle position, click a second time to determine the
perimeter of the rectangle, and measure the perimeter and area of the rectangle
:Polygon: After clicking the button with the mouse, click on any point in the
interface to determine a corner, each click will increase a corner, the last click should
overlap with the first clicked point, and measure the area occupied by the polygon
:Angle measurement: after the mouse clicks on the button, click on any point in the
interface to determine the starting point, the second click to determine the straight line,
