Snap to points by using exact distance or coordinates  numeric snapping
You can enter exact distances and coordinates when snapping to a position. This is called numeric snapping.
Enter a distance or coordinates
Use the Enter a Numeric Location dialog box to specify the distance or coordinates to a position you want to snap to.
Snapping example: Track along a line towards a snap point
Tracking means that you follow a line and pick a point at a specified distance along the line. You usually use tracking in combination with numeric coordinates and other snapping tools, such as snap switches and orthogonal snapping. This example shows how to pick a point at a specified distance along a line. Use the Enter a Numeric Location dialog box to specify the distance from the last point picked.
You can also:

Track beyond the snap point, for example 4000 units from the first point:

Track in the opposite direction by entering a negative value, for example 1000:
For an example of how to use numeric snapping in drawings, see Place a sketch object at a specified distance.
Change the snapping mode
Tekla Structures has three snapping modes: relative, absolute, and global. Use
the advanced option XS_KEYIN_DEFAULT_MODE
to indicate the default snapping mode.
Options for coordinates
The table below explains the types of information you can enter in the Enter a Numeric Location dialog box.
Note that Tekla Structures has three snapping modes: relative, absolute, and global. You can temporarily override the default snapping mode by using a special character in front of the coordinates in the Enter a Numeric Location dialog box.

Description 
Special character 

One coordinate 
A distance to an indicated direction. 

Two coordinates 
If you omit the last coordinate (z) or angle, Tekla Structures assumes that the value is 0. In drawings, Tekla Structures ignores the third coordinate. 

Three coordinates 

Cartesian coordinates 
The x, y, and z coordinates of a position separated by commas. For example, 100,50,200. 
, (comma) 
Polar coordinates 
A distance, an angle on the xy plane, and an angle from the xy plane separated by angle brackets. For example, 1000<90<45. Angles increase in the counterclockwise direction. 
< 
Relative coordinates 
The coordinates relative to the last position picked. For example, @1000,500 or @500<30. 
@ 
Absolute coordinates 
The coordinates based on the origin of the work plane. For example, $0,0,1000. 
$ 
Global coordinates 
The coordinates relative to the global origin and the global x and y directions. For example, 6000,12000,0. This is useful, for example, when you have set the work plane to a part plane and want to snap to a position defined in the global coordinate system without changing the work plane to global. 
! 
Coordinate axis prefixes 
When using direct modification, with relative and absolute coordinates, you can also use axis prefixes to allow snapping in the prefixed directions only. For example, @z500 or $y6000,z500. Axis prefixes cannot be used with global coordinates. If any of the entered coordinate values has an axis prefix, the other values need to have prefixes, too. The axis prefixes are not casesensitive, and the prefixed values can be entered in any order.
