An arc can define the edge of a face and divide a face. Although an arc is one entity, the SketchUp inference engine sees all the segments that make up the arc and highlights any geometric point if you hover your cursor over one. You can tell SketchUp how many segments to use in an arc entity.

## What does the arc tool do?

As the tool names imply, the Line Segment and Arc tools **create line segments and arcs**. As you learned in the previous exercises, the Pen tool can also create lines and arcs.

## What is ARC in drawing?

The arc is defined as **the smooth curve formed by joining two or more points**. The arc of a circle is defined as the portion of the circumference of a circle. By default, the arc is drawn counter-clockwise. We are required to press the Ctrl key to change the direction of the arc in the clockwise.

## How do you smooth an arc in Sketchup?

To smooth edges with the Eraser tool, hold down the Ctrl key (Option on the Mac) while you click or drag over the edges you want to smooth. Use **the Soften Edges panel**. Located on the Window menu, this panel lets you smooth a bunch of selected edges all at once, according to the angle of their adjacent faces.

## What arc means?

An arc is **a curve**. You can describe the bend of a rainbow as an arc. In math, an arc is one section of a circle, but in life you can use the word to mean any curved shape, like the arc of a ballerina’s arm or the graceful arc of a flowering vine over a trellis.

## Which tool is used in marking an arc?

**A compass**, more accurately known as a pair of compasses, is a technical drawing instrument that can be used for inscribing circles or arcs. As dividers, it can also be used as a tool to step out distances, in particular, on maps. Compasses can be used for mathematics, drafting, navigation and other purposes.

## What parameters do you have to specify to draw an arc?

For arc(), the x and y coordinates specify the center of the arc, relative to the top-left corner of the display area (x:0 y:0). The width and height of the rectangle that the arc is inscribed in are measured in pixels. The start parameter specifies what angle in degrees to start the arc at, 0 degrees is to the right.

## What is a 3 point arc?

: a line on a basketball court forming an arc at a set distance (such as 22 feet) **from the basket beyond which a field goal counts for three points**.
