# Coordinate input
For entries of lines, walls, bars and other inputs where a point must be chosen, various coordinate input methods are available. You call up this coordinate input by selecting a number from 1–5 on the numeric keypad. Using the correct number, you can directly invoke the appropriate function. Alternatively, you can call one of the other functions from the dialog box via a drop-down list:
The following coordinate inputs can be called by a number:
1: Relative coordinates
2: Relative angle and length
3: Global coordinates
4: Global angle and length
5: Successive angle
## Relative coordinates
With relative coordinates you define a point by specifying a distance in the X and Y directions from a reference point. The reference point is the point of a line, wall or bar that you specified previously. It is pointless to use this coordinate input for the first point of a line, wall or bar. In that case, use the object snap function Reference Point.
## Relative angle and length
With the 'Relative angle and length' coordinate input you define a point by specifying a length (distance) and an angle from a reference point. The angle is always measured relative to the global X axis. The reference point is the point of a line, wall or bar that you specified previously. It is pointless to use this coordinate input for the first point of a line, wall or bar. In that case, use the object snap function Reference Point.
## Global coordinates
With global coordinates you define a point by specifying a distance in the X and Y directions from the origin. The origin is the point in the system with coordinates X=0, Y=0, Z=0. This coordinate input can be used for all points, including the first point.
## Global angle and length
With the 'Global angle and length' coordinate input you define a point by specifying a length (distance) and an angle from the origin. The origin is the point in the system with coordinates X=0, Y=0, Z=0. The angle is always measured relative to the global X axis. This coordinate input can be used for all points, including the first point.
## Successive angle
With the 'Successive angle' function you define a point by entering a length and an angle referenced to the preceding line or wall. The previously entered line or wall must have been entered within the same 'polyline'. If the input was interrupted and you start entering a line or wall again, the previously entered line or wall does not apply. In that case the program will ask for a reference line, which can be selected graphically. This coordinate input cannot be used for the first point of a line, wall or bar.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:
```
GET https://docs.dietrichs.com/dietrichs-intelligent-documentation/docs-de-en/2d-auxiliary-geometry/fangfunktionen/koordinateneingabe.md?ask=&goal=
```
`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
