After entering CAD for so long, do you think you are a master?
Never
As the saying goes, there is still a high mountain, so many senior designers will feel that they are just a person who can skillfully operate CAD, not enough to become a master in the eyes of others.
In this way, is it difficult to get started with CAD?
This is not the case, because many times, you can master the commonly used commands in the software, and can complete some practice drawings, such as the following five, then congratulations, you can basically be called an entry, you may wish to practice drawing after collecting likes.
Everyone sees this practice drawing, and the first time you think about where to start?
1. Observe, starting from the center line, determine the hexagon in the middle, draw with an circumscribed circle, and enter a radius of 60, so that the size of the regular hexagon conforms to the above figure.
2. The RO rotates a regular hexagon, 45 degrees, marked with a standard size, yes, it is 30.
3. This time we set the drawn objects as two circles/arcs on the sides, and look at the dimensions for positioning. There are many ways to determine the center of the circle. Here is the rectangular way. Is there a better way?
Length 37.5, width 22.5
4. Three circles, two centered on the upper right corner of the rectangle, R10 and R5, and one centered on the center, R22.5.
5. After that, draw the common tangent line and the common tangent circle of R22.5 and R10. The common tangent circle can be tangent, tangent, and a radius of 30. To draw the common tangent line, after the L command is required, Shift right-click and select twice The cut point on the CAD will be adjusted automatically.
6. Trim the extra lines, make a mirror image, then trim, mark it, and you are done.
There are 4 pieces left, please complete it.
