This routine lets you create multiple points on a line or grade by specifying either the number of point you want, the spacing you want or a combination of both. The line can be any tangent, curve or spiral defined in a traverse.

- In a Traverse View, highlight the point, which is the foresight of the line you want. The multiple points will be created on the line from the previous occupied point to the foresight.
You can also pick the foresight
from the current drawing.
- Choose COGO | Multiple Points. See Accessing COGO.
- From the Multiple Points dialog, enter the
number of Points you want to create or the Horizontal or Vertical spacing points. If the line is a curve or spiral, the horizontal spacing will be computed along the arc.
- Enter the First Distance if it is something other than zero.
- Enter a staring point label for the points that will be created.
- Choose Compute.

TPC will insert the number of points into the Traverse View, adding a unique number to the point label of the occupied point. This creates a unique label for each point on the line. If the traverse is tagged in the current drawing it will draw the created points.

The Horizontal, Vertical and Points fields each has a button for the field name. When a value is entered for that field, the button changes color, indicating it being held for the computations. Fields that are not held are recomputed automatically as other data is entered.

To toggle one of these hold buttons on or off, just left click the button. They are automatically toggled to hold when you enter data in their fields.

When you enter the horizontal or vertical spacing, the program computes the number of points that can be inserted at that spacing. You can override this and enter a specific number of points to insert at that spacing.

- Enter the Horizontal or Vertical spacing.
- Enter the number of Points you want (must be less than or equal to the number of points computed). You will notice that the Points button changes color to indicate it is being held for the computations.
- Choose Compute.

To create a single point, enter 1 for number of Points and enter the distance you want for First distance. You may also need to release the Horizontal or Vertical button. This is a great way to insert a point on a spiral or curve.

- In a Traverse View, highlight the point, which is the foresight of the line you want. The multiple points will be created on the line from the previous occupied point to the foresight.
You can also pick the foresight
from the current drawing.
- Choose COGO | Multiple Points.
- From the Multiple Points dialog, enter the Vertical spacing you want. If the line is a curve or spiral, the horizontal spacing will be computed along the arc.
- Enter a staring point label for the points that will be created.
- Choose Compute.

TPC creates a point at each multiple of the vertical spacing that you specify. For example, if the **From** point has an elevation of 379 feet and the **To** point has an elevation of 385 feet and you enter a Vertical Spacing of 2 feet, TPC will create points at elevation 380, 382 and 384 feet.

TPC will insert the number of points into the Traverse View, adding a unique number to the point label of the occupied point to create a unique label for each point on the line.

When you enter the vertical spacing, the program computes the number of points that can be inserted at that spacing. You can override this and enter a specific number of points to insert at that spacing.

- Enter the Vertical spacing.
- Enter the number of Points you want (must be less than or equal to the number of points computed.
- Choose Compute.

Multiple points are computed based on the distance type of each alignment traverse.

For example, if a traverse is formatted for ground distance at project elevation, multiple points inserted anywhere in that traverse will be ground distance at project elevation. So you can create stationing for grid, ground or geodetic.
