Draw Circle

Function Description

There are several ways to create a circle. This can be done by specifying Center, Radius, diameter, point on circumference, and so on. Application provides five ways to draw a circle. The default drawing method is to specify a center point and radius.

Operating instructions

Draw a circle by its center and radius
  1. On the Object Operation tab, in the Object Drawing group, click the Face Drop-down Button and select the Center, Radius button from the drop-down menu to display the center circle cursor.
  2. Move Stop by Mouse to Map, and you can see that the coordinate value of the current mouse position will be displayed in the Parameter Input box in real time as the mouse moves. Enter the coordinate value of the center point in the Parameter Input box (you can switch between the two Parameter Input boxes by pressing the Tab key) and then press the Enter key to determine the center of the circle.
  3. Move the mouse again, enter the radius (length) in the Parameter Input box, and press Enter to complete the drawing.

Draw a circle by diameter

  1. On the Object Operation tab, in the Object Drawing group, click the Face Drop-down Button and select the Starting Point, Diameter option. The circle cursor appears.
  2. Move Stop by Mouse to Map, and you can see that the coordinate value of the point will be displayed in the Parameter Input box in real time as the mouse moves. Enter the coordinate value of the diameter starting point in the Parameter Input box (you can switch between the two Parameter Input boxes by pressing the Tab key) and then press the Enter key to determine the diameter starting point.
  3. Move the mouse, and you can see that as the mouse moves, the length of the line connecting the mouse position and the starting point of the diameter and the included angle between the line and the positive direction of the X axis will be marked in the Map in real time (you can switch between the two Parameter Input boxes by pressing the Tab key). Enter the length and angle values in the Parameter Input box.
  4. When the diameter is determined, press Enter to complete the circle.

Draw a circle through two points on the circumference

  1. On the Object Operation tab, in the Object Drawing group, click the Face Drop-down Button and select the Two Points option. The circle cursor appears.
  2. Move Stop by Mouse to Map, and you can see that the coordinate value of the current mouse position will be displayed in the Parameter Input box in real time as the mouse moves. Enter the coordinate value of a point on the circle in the Parameter Input box (you can switch between the two Parameter Input boxes by pressing the Tab key) and then press the Enter key to determine a point on the circle.
  3. Move the mouse. As the mouse moves, enter the coordinate value of another point on the circumference in the following Parameter Input box (you can switch between the two Parameter Input boxes by pressing the Tab key).
  4. When you press Enter, the circle object is drawn with the distance between the two points on the circumference as the diameter.

Draw a circle through three points on the circumference

  1. On the Object Operation tab, in the Object Drawing group, click the Face Drop-down Button and select the Three Points option. The three-point circle cursor appears.
  2. Move Stop by Mouse to Map, and you can see that the coordinate value of the point will be displayed in the Parameter Input box in real time as the mouse moves. Enter the coordinate value of the first point on the circle in the Parameter Input box (you can switch between the two Parameter Input boxes by pressing the Tab key) and then press the Enter key to confirm the coordinate of the first point on the circle.
  3. Move the mouse, enter the coordinate value of the second point on the circle in the following Parameter Input box (you can switch between the two Parameter Input boxes by pressing the Tab key), and then press the Enter key to confirm the coordinate of the second point on the circle.
  4. Move the mouse, enter the coordinate value of the third point on the circle in the following Parameter Input box (you can switch between the two Parameter Input boxes by pressing the Tab key), and then press the Enter key to draw a circle passing through the three points.

Draw Rectangle's Circumscribed Circle

  1. On the Object Operation tab, in the Object Drawing group, click the Face Drop-down Button and select the Circum circle of Rectangle option. The Circumcircle of Rectangle cursor appears.
  2. Move Stop by Mouse to Map, and you can see that the coordinate value of the point will be displayed in the Parameter Input box in real time as the mouse moves. Enter the coordinate value of the starting point of the rectangle in the Parameter Input box (you can switch between the two Parameter Input boxes by pressing the Tab key) and then press the Enter key to confirm the position of the starting point of the rectangle.
  3. Move the mouse. As the mouse moves, the Parameter Input box displays the height and width of the rectangle in real time (you can switch between the two Parameter Input boxes by pressing the Tab key). Type the width and height of the rectangle in the Parameter Input box.
  4. When you press Enter, the circumcircle of the rectangle determined in the previous step is created.
Caution:
The circles drawn in

Online Data are all ordinary line objects, and only the coordinates of each node on the line are recorded. However, the circle objects drawn in CAD Dataset are parametric objects, and the corresponding parameters, such as radius and center, are recorded.
