TPC uses conventions for entering values like bearings and stations. This topic explains these conventions.
TPC uses numbers to specify compass quadrants where1=NE, 2=SE, 3=SW and 4=NW. You enter bearings using the quadrant number then the bearing. Put a period after the degrees, then type the minutes and seconds.
For example, N 30°45'10" E is entered as 130.4510.
Use a single decimal point in the degree position and don’t use any other punctuation or spaces.
Angles are entered with the degrees followed by a period and then the minutes and seconds.
For example, 30°45'10" is entered as 30.4510.
Use a single decimal point in the degree position and don’t use any other punctuation or spaces.
There are several ways to enter a degree symbol in Drawing View.
You can recall data using existing points and entering equations. For instance, to recall the bearing between points 11 and 12, type 11..12 in the bearing field and press [Enter]. To recall the elevation of point BM14, type BM14 in the elevation field and press [Enter].
You can also add, subtract, multiply and divide using recalled data. For instance, to recall half the distance between points 11 and 12, type 11..12/2 or 11..12*.5 in the distance field and press [Enter].
You can use an equation any place you would normally enter a distance, bearing, elevation or coordinate.
Here’s how they work:
If you are in a direction field, the equation returns a direction. If you are in a distance field, the equation returns a distance. If you are in an elevation field, the equation returns an elevation.
The following symbols are valid: (+ = add, - = subtract, * = multiply, both / and \ = divide, F and f and ‘ = feet, I and i and “ = inches).
Use two periods .. or a comma to separate point labels.
If a point label contains a valid equation symbol, follow it with two periods. For example, 10+00..12+45..+50 recalls the data between points 10+00 and 12+45 and adds 50 to it. You can also use ( ) as in 10+00..(12+45)+50. To recall the elevation of 12+45, use the equation 12+45.. or (12+45) in an elevation field.
Enter 10 feet, 8 and 13/16 inches as 10F8I13 or 10f8i13 or 10’8”13. TPC will convert it to feet and display the equivalent decimal feet. 10f8i13 is redisplayed as 10.73 in the distance field of the Traverse View.
This feature is not included in the Property Edition.
Enter the station 12+50.45 as 12+50.45, just like it is displayed. TPC converts the number before the + to a station and the number to the right of the + as the units.
An Imperial station is always 100 feet. A metric station, however, can be 100 meters or 1000 meters. You can choose which one to use by choosing Tools | Program Settings | Units.
This feature is not included in the Property Edition.
Enter Latitude positive = North, negative = South or include the letter N before or after the value for North or the letter S before or after the value for South. Example: enter N42.1334568 for 42°13’34.568” North.
Enter Longitude positive = East, negative = West or include the letter W before or after the value for West or the letter E before or after the value for East. Example: enter W128.1334568 for 128°13’34.568” West.
Use a single decimal point in the degree position and don’t use any other punctuation or spaces.
You can edit existing data in the Traverse View at any time. Use the up, down, left and right arrow keys or your mouse to select the field you want to edit and enter the new data. This will replace all of the data in the field.
To edit a portion of the data in a field, press the space bar on your keyboard after selecting the field. You can then edit any part of the data in the selected field.
When you update raw data, you may need to recompute (Tools | Recompute) the traverse to update coordinates based on the new raw data. If you enter new data and it immediately reverts to the original value, recompute the traverse.
