When a command asks for a point, you can use the pointer tool (e.g. mouse or touchpad) to specify the point or enter its coordinates. If dynamic input is turned on, you can enter coordinate values in an input field near the cursor.

Cartesian Coordinates

A Cartesian coordinate system has three axes, X, Y, and Z. When you enter coordinate values, you indicate a point's distance and its direction (+ or -) along the X, Y, and Z axes relative to the coordinate system origin (0,0,0).

In 2D view, you specify points on the XY plane that is similar to a flat sheet of grid paper. The X value of a Cartesian coordinate specifies horizontal distance, and the Y value specifies vertical distance. The origin point (0,0) indicates where the two axes intersect.

Another method of specifying a point is by moving the cursor to indicate a direction, and then entering a distance. This method is called direct distance entry.

Note:*Coordinates and distances are always measured in units such as millimeters, meters, or inches. In the Units and Angles panel of the Options dialog, you can set the distance that a unit represents in the drawing.*

**Cursor Input Box**

When you are in input mode and need to specify a point, ARCHLine.XP displays the Cursor Input Box.

This transparent box helps you display and change the length, angle, or X and Y distance of a vector. Press TAB to edit a value.

The software will let you edit the first value of the box. When you press TAB again, you can jump to the following value.

When you edit a value and hit the Enter on your keyboard, the software will close the edit field, and fix the value typed. This way you can fix e.g. the inclination of a wall for example when drawing it.

Turn on or Turn off cursor input Box : Click on the Enable Cursor Input Box input button on the Options dialog to turn the Cursor Input Box on and off.

Display Type Settings: Set the information you want to view.

Distance, Angle and Relative Coordinates:

**Defining coordinates**

This can be set in the Status bar.

**Defining points with snap grid**

Snap grid is of great help when defining points. It locks the cursor into alignment with the grid points.

This can be set in the Status bar.

### Object snaps

Object rasters provide an opportunity to determine the exact location of the input.

If you want the input to always use special point detection, you can turn on automatic detection. For example, you can set endpoint, midpoint, and midpoint as auto-recognized special points.

This can be set in the Options dialog - Snap and grid panel.

**Specifying a Point Relative to an Existing Point**

You can use the reference point method whenever the software asks for a point.

You can specify a point that is located a specified distance and direction from a reference point.

The next coordinate, value is calculated relative to the reference point.

Example:

*Using the reference point, you can easily specify a wall that starts 3 m from the end point of an already drawn wall. Start the Create Wall command, then click the Reference Point button on the status bar and click on the end point of the wall.**Drag the cursor horizontally / vertically and enter the distance in the given direction (3 m). Press Enter. This will move the starting point of the new wall creation to the point at the specified distance from the reference point.*

**Unique special point input**

In the status bar, click the Reference toolbar icon, then click the criterion you want to use when entering the next input point.

Reference toolbar can be set in the Status bar.

Endpoint | Defines the endpoint of the selected object. |

Midpoint | Defines the middle point of the selected object. |

Distance from endpoint | Defines a new point as a point on the selected object at a specified distance from the endpoint nearest to the selected point. |

Distance from intersection | Defines a new point as a point on the selected object at a specified distance from the nearest intersection point. |

Half division point | Divides the distance between two points into half. |

Centre point | Defines the centre of an object. |

Intersection point | Defines the nearest intersection point on the selected object. |

Apparent intersection point | This command is able to find the intersection point of two selected objects. |

Reference point | The selected point becomes the reference point. |

Nearest point | Defines the nearest point of the selected object. |

Parallel direction | The next input coordinate is in direction of the selected object or in the direction of the tangent of the selected object. |

Perpendicular direction | The direction of the next input coordinate is perpendicular to the selected object or to the tangent drawn in the selected point. |

Relative distance | The next point will be defined in X, Y distance. |

Relative polar distance | Defines the new point at a given angle with a given radius from the last point. |

Coordinate-, distance, locking direction:

** **

Lock X coordinate | Locks the absolute / relative X coordinate of the new point. A line appears and the program recognizes only the points of this line. |

Lock Y coordinate | Locks the absolute / relative Y coordinate of the new point. A line appears and the program recognizes only the points of this line. |

Lock radius | Having locked the radius a circle appears, after this the cursor finds only the points of this circle. |

Lock direction | If you lock the value of the angle a line appears in the given direction. After this the cursor finds only the points of this line. |

Lock angle | Locks the actual editing direction graphically. After this the cursor finds only the points of this line. |

Projections:

Reference direction perpendicular | The new point will be in the intersection of the locked direction and the perpendicular projection of the selected reference point. |

Reference direction horizontal | The new point will be in the intersection of the locked direction and the horizontal projection of the selected reference point. |

Reference direction vertical | The new point will be in the intersection of the locked direction and the vertical projection of the selected reference point. |

**Orthogonal Locking (Ortho Mode)**

You can restrict cursor movement with pressing SHIFT button down to horizontal and vertical directions for convenience and precision when creating and modifying objects.

**Defining direction with arrows**

You can define in which direction to create an object with the arrow keys of the keyboard.

In this case the arrow keys substitute the direction definition of the polar coordinate.

• Press any arrow button to define drawing direction.

• Specify the length of the object to be created.

The program creates the object of the specified length in the direction defined by the arrow.
