Let's try a project using what we've learned. We'll draw the Ring Stand Base shown in Figure 5.5a.
Create a new drawing with the following setup:
Lower left limits: 0,0
Upper right limits: 17,11
Units: Architectural
Grid: ½
Snap: ¼
Textsize: 3/8
Font: Times New Roman
Follow these steps.
Tools | Command Sequence | Steps |
---|---|---|
| Command: z | 1. Zoom All to see the entire drawing. |

| Command: l | 3. Enter the Line command. |
Specify first point: 4,2-1/2 Specify next point or [Undo]: @3<90 Specify next point or [Undo]: [enter] | 4. Start at point 4,2 ½ and draw a 3" line upward. | |
| Command: [enter] Specify first point: 4-1/2,2 Specify next point or [Undo]: @5<0 Specify next point or [Undo]: [enter] | 5. Repeat the Line command. Then draw the second line as indicated. |

| Command: os | 8. Set the Running OSNAP to endpoint . Clear all other settings. (Remember to toggle the Running OSNAP On or Off using the F3 function key or the status bar toggle as needed!) |
| Command: a | 9. Enter the Arc command. |
Specify start point of arc or [Center]: | 10. Select the endpoint of the second line nearest the fourth line. | |
Specify second point of arc or [Center/End]: c | 11. Use the Center option. | |
Specify center point of arc: | 12. Snap to the grid mark directly above the point you selected in Step 11. | |
Specify end point of arc or [Angle/chord Length]: | 13. Select the lower endpoint of the fourth line. | |
| Command: a | 14. Repeat Steps 9 through 13 to draw the other three arcs. Your drawing now looks like Figure 5.5.1.14a. |
| ||
| Command: l | 15. Repeat the Line command. |
Specify first point: Specify next point or [Undo]: @1<180 Specify next point or [Undo]: [enter] | 16. (Refer to Figure 5.5.1.14a.) Draw a 1" line from the left endpoint of the second line in the 180 ° direction. | |
| Command: l | 17. Repeat Step 16 at all four corners. Your drawing will look like Figure 5.5.1.17a. |
| ||
| Command: a Specify start point of arc or [Center]: 3-1/2,2-1/2 | 18. (Refer to Figure 5.5.1.17a.) Now we'll draw an arc at the end of the first line. Start the command at the point indicated. |
Specify second point of arc or [Center/End]: c | 19. Use the Center option. | |
Specify center point of arc: | 20. Select a point one snap down from the point selected in Step 18. | |
Specify end point of arc or [Angle/ chord Length]: | 21. Select the endpoint of the first line. | |
| Command: a | 22. Repeat Steps 18 through 21 at the other four lines. Your drawing will look like Figure 5.5.1.22a. |
| ||
| Command: l Specify first point: Specify next point or [Undo]: @1/4<0 Specify next point or [Undo]: [enter] | 23. Now add a ¼" line at the end of the first arc. Repeat for each arc. Your drawing will look like Figure 5.5.1.23a. |
| ||
| Command: a Specify start point of arc or [Center]: [select the endpoint of the line at the first arc] | 24. Now draw arcs at the end of the new lines (refer to Figure 5.5.1.29a). We'll start at the lower left corner. |
Specify second point of arc or [Center/ End]: e | 25. Use the End option. | |
Specify end point of arc: | 26. The endpoint is one snap up and one snap to the right. | |
Specify center point of arc or [Angle/ Direction/Radius]: d | 27. Select the Direction option. | |
Specify tangent direction for the start point of arc: | 28. Select a point to the right of the point selected in Step 24. | |
| Command: a | 29. Repeat Steps 24 through 28 for the other arcs. Your drawing looks like Figure 5.5.1.29a. |
| ||
| Command: qsave | 30. It's a good idea to save your drawing occasionally! |
| Command: c | 31. Draw a circle in the center of the first anchor leg. |
| Specify center point for circle or [3P/2P/Ttr (tan tan radius)]: _cen of | 32. Use the center OSNAP to locate the center of the first arc. |
Specify radius of circle or [Diameter]: 1/8 | 33. Use a 1/8" radius for the circle. | |
| Command: c | 34. Repeat Steps 31 through 33 for each of the anchor legs. Your drawing will look like Figure 5.5.1.34a. |
| ||
| Command: c Specify center point for circle or [3P/2P/Ttr (tan tan radius)]: 5,4 Specify radius of circle or [Diameter] <0'-0 1/8">: 1/2 | 35. Now draw the 1" washer using the Circle command. |
| Command: c Specify center point for circle or [3P/2P/Ttr (tan tan radius)]: 5,4 Specify radius of circle or [Diameter] <0'-0 1/2">: 1/8 | 36. Draw the ¼" bolt center using the Circle command. |
| Command: pol | 37. Draw the bolt using the Polygon command. |
Enter number of sides <4>: 6 | 38. Give it six sides. | |
| Specify center of polygon or [Edge]: _cen of | 39. Place it in the center of the last circle you drew. |
Enter an option [Inscribed in circle/Circumscribed about circle] <I>: c | 40. Since we've a dimension on the bolt from flat side to flat side, we'll draw the polygon around a circle with that diameter. Type c for Circumscribed . | |
Specify radius of circle: 7/32 | 41. Type in 7/32 (half the given diameter). Your drawing now looks like Figure 5.5.1.41a. | |
| ||
| Command: el | 42. Now let's draw the logo plate using the Ellipse command. |
Specify axis endpoint of ellipse or [Arc/Center]: 8-1/2,3 | 43. Start at point 8 ½,3 . | |
Specify other endpoint of axis: @2<90 | 44. The ellipse is 2" along the long axis. | |
Specify distance to other axis or [Rotation]: @1/2<0 | 45. it's 1" along the short axis. | |
Command: dt | 46. Add the ACME text to finish the project. | |
Current text style: "times" Text height: 0'-0 3/8" Specify start point of text or [Justify/Style]: m Specify middle point of text: 8-1/2,4 | 47. We'll middle-justify the text in the center of the ellipse. | |
Specify height <0'-0 3/8">: [enter] | 48. If you set the textsize to 3/8 during the setup, it will default to that now. Otherwise, set it to 3/8 . | |
Specify rotation angle of text <0>: 90 | 49. Set the rotation angle so the text may be read from the bottom of the stand. | |
Enter text: ACME Enter text: [enter] | 50. Enter the text. | |
| Command: qsave | 51. Save your drawing. It should now look like the sample in Figure 5.5a. |
