In this lesson you will draw out a plat of a single lot, using Carlson drafting techniques. You will make the plat from an ASCII file of points named Plat.txt.
Prompt(s) | Response | Narrative |
---|---|---|
[Continue/Extend/Follow/Options/<Pick point or point numbers>]: | 1 | This instructs the 2D polyline to commence at Point #1. |
[Arc/Close/Distance/Follow/Undo/<Pick point or point numbers>]: | 8 | This instructs the 2D polyline to be drawn to Point 8 |
[Arc/Close/Distance/Follow/Undo/<Pick point or point numbers>]: | press Enter | This creates a polyline. Keep this as a separate polyline because later you will turn this back lot line into a fence line. Press Enter to repeat the 2D Polyline command. |
[Arc/Close/Distance/Follow/Undo/<Pick point or point numbers>]: | 8-10 | This instructs the 2D polyline to be drawn through Points 8, 9 and 10. |
<Pick point or point numbers> | a | This indicates a tangential arc to be drawn starting from Point 10. |
[Radius pt/radius Length/Arc length/Chord/Second pt/Undo/<Endpoint or point number>]: | 15 | This indicates the arc shall terminate at Point 15. |
[Arc/Close/Distance/Extend/Follow/Line/Undo/<Pick point or point numbers>]: | 1 | This instructs the polyline to be drawn back to the starting point. The segment from 15 to 1 is not guaranteed to be tangent to the previous arc. |
[Arc/Close/Distance/Follow/Undo/<Pick point or point numbers>]: | press Enter | This creates the full lot. |
Brian W. and Mary T. Jones (press Enter)This produces parallel, center-justified text on the west side of the property. Press Enter to repeat the command and complete the following prompts:
D.B. 101, P. 37 (press Enter twice)
Stan W. Bosworth (press Enter)The results are shown here:
D.B. 94, P. 272 (press Enter twice)
Surveyor's CertificationThe command "wraps" the text when it runs out of space in the MText window. Click OK at the upper right to place this text into the drawing.
I do hereby certify that the survey shown heron was performed under my direction by method of random traverse and that the error of closure was 1:52544.
