## How do you draw an arc with a specific length and radius in AutoCAD?

It could of course be done by calculating the angle mathematically, but an easier way to do it is to draw the arc with the required radius and centre point, then modify it using the lengthen tool on the Modify tab drop down. The arc will now be the desired length.

## What is AutoCAD radius?

Determines the radius of a selected object. The object can be a circle, an arc, or a 2D polyline arc segment. The following example uses rad with the CIRCLE command. The radius of the new circle is two-thirds of the radius of the selected polyline arc segment: Command: circle.

## What is a radial dimension?

A radial dimension is a group design object. It allows for the dimensioning of a radius with respect to an arc or circle. The dimension can be placed either internally or externally in relation to the circumference of the arc/circle.

## How do I find the length of an arc?

To calculate arc length without radius, you need the central angle and the sector area:

- Multiply the area by 2 and divide the result by the central angle in radians.
- Find the square root of this division.
- Multiply this root by the central angle again to get the arc length.

## What is common to freeze and lock options in layers?

You can prevent layers from being regenerated with the other layers in a drawing. They can be made visible or invisible, and made available or unavailable for editing. This section describes these options and suggests the circumstances for using them.

## How do you find the area of an irregular curved shape?

Evaluating area using unit squares

Apply this technique for the shapes with curves apart from perfect circle or semicircles and irregular quadrilaterals. In this method, divide the shape into unit squares. The total number of unit squares falling within the shape determines the total area.
