Recently, some friends have consulted the editor on how to draw an oval gland in CAD2018. The following will bring you the method of drawing an oval gland in CAD2018. Friends in need can come and learn more.
The first step: Open the CAD2018 software and create a new drawing interface (as shown in the picture).
Step 2: Use the circle command C to draw a concentric circle with the diameters of 22 and 38, named concentric circle 1 (as shown in the figure).
Step 3: At a position 26 to the left of the center of the concentric circle, also use the circle command C to draw a concentric circle. The diameters of the circles are 10 and 20 respectively. Name it concentric circle 2 (as shown in the figure).
Step 4: Use the mirror command MI, take the vertical center line of the center of concentric circle 1 as the mirror line, mirror concentric circle 2 to the right, and name it concentric circle 3 (as shown in the figure).
Step 5: Enter the straight line command L, press the space bar, enter TAN, press the space bar again, move the mouse over the diameter 20 circle of concentric circle 2, a tangent symbol will appear, click it to draw a main line, and then enter TAN Press the space bar, move the mouse over the diameter 38 circle of concentric circle 1, a tangent symbol will appear, click it, and the tangent line will be drawn (as shown in the picture).
Step 6: Use the mirror command to mirror the other three tangent lines (as shown in the figure).
Step 7: Use the trimming original TR to trim the corresponding line segments, so that an elliptical gland is drawn (as shown in the picture).
The above is the entire content of how to draw an oval gland in CAD2018 brought to you by the editor. I hope it can help you.
