The problem of drawing arcs
Thread Content
I would like to ask everyone: what is the simplest way to draw an arc with a known length and radius? Thank you for your advice
If you want to draw an arc with a radius of 10 and a length of 30, first draw an arc with a radius of 10 but any arbitrary length, such as a semicircle. Then use the “lengthen” command; four options will be presented: incremental, percentage, total, and dynamic. Choose “total”, enter 30, and then select the arc as instructed – the arc’s length will then become 30
1. Draw a line segment whose length is equal to the radius. 2. Use the arc command to draw an arc: specify one end point of the line segment as the center of the circle, and the other end point as the starting point of the arc; by specifying the arc length, the desired arc can be drawn. 3. Delete the line segment
The arc length can be converted into an angle. 1. ARC 2. C 3. Specify center point 4. Specify start point of arc 5. Calculate angle (convert arc length to angle) 6. A 7. Specify angle value. Last edited by white36 on 2007-12-19 22:31]
Good idea; I learned another command: lengthen. The method on the third floor is not feasible; what can be specified is the length of the chord, not the length of the arc. It’s not possible to create an accurate drawing on the fourth floor.
