In these cases you also need to type 4s. The arc now has four segments. 14. Once you create another object or activate another tool you can no longer change the arc this way the 4s method . But for another way to change the arc open its Entity Info window. Both the radius and number of segments can be edited. 15. Change the segment number to 8 and enter a slightly smaller radius don t forget the units symbol if necessary . 16. The arc shrinks resizing the rectangle below it as well. 17. Now make the arc radius larger. Note that even if you are using architectural units you can still enter a decimal value is the same as 2 -6 . This time the arc updates but does not affect the rectangle now a trapezoid below it. This is because an arc can be fit to the current edge below at a size less than a semi-circle. But if the new radius will make an arc greater than a semi-circle the edge below will update instead. 18. Erase the line between arc and rectangle and erase the face. 19. For the next arc use the bottom edge of the cutout as the chord and set the arc upward blue direction . Note that it has four segments this reflects the last arc change you made and does not take into account the change you made via Entity Info. 23 the SketchUp Workbook Version 5 20. Type 8s to make the arc rounder. 24. Now draw an arc that sticks out of the side face and close it with a line. Leave room on this face for another similar arc. 21. Like a circle an arc can be broken down into individual segments. Right-click the arc and select Explode Curve. 22. Each segment is now a separate entity. Erase the top four segments. . . 25. Draw the next arc at the same height by hovering over an endpoint of the first arc and dragging the cursor to the right . To set the bulge you can pick the bulge point of the first arc. 23. . . . and draw a line to connect the ends of the 26. .
