CAD experts, come take a look and see what’s going on here

I’m a beginner in CAD. It’s really ried and GOUed. Why does this circle have 362 degrees again? I’m almost laughing myself to death; I don’t know what’s wrong. My method is: to use tangent circles to capture the nearest point

Do you see the center line right below? It’s not vertical; P and P are both like this.

Can’t you just draw an inscribed hexagon directly? ? ? ? ? ? ? ? ?

For hexagons, the direction of rotation always matters, but circles don’t require a direction of rotation. . . ;P Find some reason for my novice behavior.

There are many reasons for this outcome; for example, changing the label to P, or the positioning of the annotation points being incorrect. You can simply draw a straight line and rotate it twice to ensure the angle is correct

That is not a vertical line. It’s a line connecting two centers; theoretically it should be straight, but it isn’t.

Most likely reason: there is a problem with the circles you drew; perhaps they are not perfectly tangent to each other. Adjust the labeling precision (to show two decimal places) and you’ll naturally understand what’s going on. Or, if you delete everything and redraw it carefully, the problem will go away.

There are experts upstairs. The vertical line in the middle is drawn separately; it’s actually not vertical. The ripples can be seen.
