Snap to points 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.
- Run a command that requires you to pick points.
For example, start creating a beam.
- Enter a distance or coordinates by using the keyboard.
For example, type 1000 as the distance from the last point picked. When you start typing, Tekla Structures displays the Enter a Numeric Location dialog box automatically.
- After entering the distance or coordinates, click OK or press Enter to snap to the position.
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 orthogonalview projection that displays objects in right-angles projection
In orthogonal model view the size of the objects is the same despite of their distance to the viewing point and the zoom remains on part faces.
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.
- Create two beams and place them as shown below:
- Activate the beam command, to create one more beam.
- Pick the first point.
- Move the mouse pointer over the grid linesingle line that visualizes a grid plane or a curved grid surface on a view plane
midpoint, so that it locks onto the snap pointpoint to which Tekla Structures snaps
, but do not click the mouse button.
- Type 1000.
When you start typing, Tekla Structures displays the Enter a Numeric Location dialog box.
- Click OK to confirm the distance.
Tekla Structures creates a beam, which is 1000 units long and positioned between the points you defined:
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.
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.
You can enter
A distance to an indicated direction.
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.
The x, y, and z coordinates of a position separated by commas.
For example, 100,-50,-200.
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.
The coordinates relative to the last position picked.
For example, @1000,500 or @500<30.
The coordinates based on the origin of the work plane.
For example, $0,0,1000
The coordinates relative to the global origin and the global x and y directions.
For example, !6000,12000,0.
This is handy, 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.
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.
- On the File menu, click Settings > Advanced Options and go to the Modeling Properties category.
- Set the advanced option XS_KEYIN_DEFAULT_MODE to RELATIVE , ABSOLUTE , or GLOBAL.
- In the relative snapping mode, the coordinates you enter in the Enter a Numeric Location dialog box as such without any prefix are relative to the last position picked.
- In the absolute snapping mode, the coordinates are based on the origin of the work planeplane that the user has chosen in a model and that is currently active for working on in a model view
Newly created, copied, or moved model objects comply with the work plane. For example, shifting the work plane to follow a sloped plane makes it easier to model sloped structures.
- In the global snapping mode, the coordinates are based on the global origin and the global x and y directions.
- Click OK to save the changes.
- If you want to temporarily override the default snapping mode, enter a special character in front of the coordinates when entering a numeric location.
By default, the special characters are:
- @ for relative coordinates
- $ for absolute coordinates
- ! for global coordinates
If you want to change the special character for any of the three snapping modes, use the advanced optionssettings used to customize Tekla Structures for specific companies, standards, users, or user groups
In Tekla Structures, advanced options are settings that are used, for example, in a specific project or geographical area, or by a specific company.
In Tekla Structures, advanced options usually begin with the initials XS and are followed by the name of the function, for example XS_BACKGROUND_COLOR.
XS_KEYIN_RELATIVE_PREFIX , XS_KEYIN_ABSOLUTE_PREFIX , and XS_KEYIN_GLOBAL_PREFIX.
