How to draw an ellipse in carpentry decoration?

Carpenters play an important role in home decoration. With their skillful hands, they create pieces of wooden furniture that are works of art, decorating our beloved homes and making them shine.

The reason why carpenters are so good is that they have a solid foundation, which they have all worked incredibly hard to achieve.

When a whole board lies before you, the carpenter has already dismantled it into eight pieces. It's as if countless lines have appeared out of thin air on the board, shining with their trajectory, guiding the carpenter to dissect it and complete its mission.

That's right, drawing lines is both a basic skill and a profound art; the higher one's skill level, the more refined one becomes.

The ellipse seems to have become an unavoidable hurdle in woodworking line drawing.

As a foundation, the ellipse seems to be an unavoidable hurdle in woodworking line drawing, unlike the perfect circle, and I guess everyone has forgotten how the ellipse is defined in mathematics.

Go and look it up in a book; I won't explain it here, it's too difficult, and I'm afraid I might misunderstand or misinterpret it. I'll just explain the drawing method here:

This is the most common drawing method used in carpentry. It mainly involves determining the positions of points D and E through mathematical definitions. After finding these two points, nail them in place. Then, find a sturdy line with a length equal to the distance between AE and DB. Next, hold a pen against the line and make a circular motion to complete the ellipse. It is best to do this in one go.

There is also an ellipse compass, which carpenters can use to draw ellipses, but the disadvantage is that the distance is limited.

If you absolutely need a very precise ellipse, you can draw it on a computer using CAD, print it out to scale, and then trace it onto a wooden board. For sizes larger than a certain point, you can piece together several sheets of paper; you could give it a try.

With a pen, a string, two nails, and a little math knowledge, drawing an ellipse is a piece of cake.

Of course, the best way is the first one: a pen, a string, two nails, and if you know a little math, drawing an ellipse is a piece of cake.
