How to draw arc length in CAD
In CAD design, drawing arc length is a common but confusing operation. This article will explain in detail how to draw an arc with a specified arc length in CAD, and also attaches hot topics and hot content in the past 10 days to help readers understand the current focus of society.
1. Steps to draw arc length in CAD
1.Open CAD software: Start AutoCAD or other CAD software and create a new drawing file.
2.Select drawing tool: Find the "Arc" tool in the toolbar, or enter the "ARC" command.
3.Specify starting point and center point of circle: First click or enter the coordinates of the starting point, and then specify the center position of the circle.
4.Enter arc length: Enter "L" in the command prompt to select the arc length option, and then enter the desired arc length value.
5.Complete drawing: After confirming the arc length, the arc will be automatically generated.
2. FAQs
Q: How to accurately control the arc length?
A: You can use the "LENGTHEN" command to precisely adjust the arc length, or by entering specific values.
Q: What is the relationship between arc length and radius?
A: The relationship between arc length (L), radius (R) and central angle (θ) is: L = R × θ (θ is in radians).
