Snap to lines, edges, and extension lines
You can snap to lines when you model objects that should be lined up with an existing object or with a grid linesingle line that visualizes a grid plane or a curved grid surface on a view plane
. You can also snap to the extension lines of part reference lines, or to the extension lines of nearby objects' reference lines.
Snap to a line or an edge
Use the Snap to line snap switchswitch used for controlling what kind of points Tekla Structures snaps to
The user needs to activate snap switches to be able to pick different points, for example, line ends and intersections.
Snap switches help the user to pick points in order to position model objects precisely without having to know the coordinates or create additional lines or points.
when you need to snap to another line in the model. You can snap to gridmodeling aid that represents a three-dimensional complex of intersecting grid planes or intersecting grid planes and curved grid surfaces
The grid is defined by coordinates in 3D space. It is shown two-dimensionally on the view plane by dash-and-dot lines. A grid can be rectangular or radial.
It is possible to have more than one grid in a model. For example, a large-scale grid for the entire structure, and smaller grids for some detailed sections.
It is also possible to show grids and grid line labels in drawings, and to modify how they are shown in the drawings.
lines, reference lines, and the edges of existing objects.
Use the Snap to line snap switch when you need to create, for example, several beams one after another on a grid line. With the Snap to line snap switch you do not need separately pick the start point and the end point of the beam.
- Ensure that theSnap to line snap switch is active.
- Run a command that requires you to pick two or more points.
For example, start creating a beam. When you move the mouse pointer over a grid line or a nearby object, Tekla Structures automatically picks both ends of the line. The yellow arrow symbol indicates the direction of the points.
- To switch direction, move the mouse pointer closer to the opposite end of the line.
- Click the left mouse button to confirm the snap position.
Tekla Structures creates the object. For example:
If you use the Snap to line snap switch with a command that requires only one point to be picked, for example when creating a column, only the start point of the line is used to position the part.
Snap to extension lines
Use the Snap to extension lines snap switch when you need to snap to the extensions of the part reference lines, which are the lines between part handles, or to the extensions of nearby objects' reference lines. The extension line(1) line in a drawing that is perpendicular to a dimension line and that connects the dimension line to the building object
(2) temporary line in a model that can be used for aligning objects with each other
(2) Extension lines can be used when snapping or creating points.
is shown as a blue, dashed line.
The Snap to extension lines snap switch works with beams, polybeams, plates, and slabs.
With beams, the extension line is the line that passes through both of the part handles.
With polybeams, plates, and slabs, the extension lines are the lines that pass through to the consecutive part handles.
With beams and polybeams, you can snap to the line that passes through the handle at the end of the beam, and which is perpendicular to the direction of the beam.
When you snap to the extension lines of nearby objects, the extension line snaps to the direction of the nearby object and the extension line indicates the direction that is followed in snapping. Snapping to the extension lines of nearby objects can be useful, for example, when you want to align objects with one another.
The Snap to reference lines and points and Snap to geometry lines and points snap switches do not affect the Snap to extension lines snap switch.
- Ensure that the correct snap switches are active:
Switch onSnap to extension lines.
Switch on eitherSnap to intersection points orSnap to nearest points (points on line) if you are snapping to the intersection of an extension line and a grid line.
Switch offSnap to end points if you are working in 3D.
- Run a command that requires you to pick points.
For example, start creating a beam, a plate(1) part that represents a flat structure
(1) In some contexts, for example in analysis, the term plate object may be used to refer to plates.
(2) plate that represents a steel structure
(2) Plate is mainly used as a connection piece or as a floor plate.
, or slabplate that represents a concrete structure
In Tekla Structures, a slab is created by picking three or more points.
Slab may be part of a floor, for example.
- Move the mouse pointer over an existing object to see the extension lines.
When a line is found, you can move the pointer further away while keeping the snap.
- Pick the rest of the points.
Tekla Structures creates the object:
Lock X, Y, or Z coordinate on a line
You can lockto prevent unwanted action in a model or a drawing
It is possible to lock model objects, reference models, and drawings, for example.
the x, y, and z coordinates on a line. This is useful when you need to determine a point to pick and the needed point does not exist on the line. When a coordinate is locked, you can only snap to points in that direction.
- Run a command that requires you to pick positions.
For example, start creating a beam.
- Lock a coordinate:
To lock the x coordinate, press X.
To lock the y coordinate, press Y.
To lock the z coordinate, press Z.
Now you can only snap to points in the chosen direction.
Tekla Structures indicates the locked coordinate with the letters X , Y , or Z in the status bar at the bottom of the Tekla Structures main window.
- To unlock the coordinate, press the same letter ( X , Y , or Z ) again.
Align objects using a snap grid
A snap gridarea covered with regularly spaced snap points
makes it easier to align objects in a model, because it allows you to snap to positions only at set intervals. Use a snap grid when you pick points using theSnap to any position snap switch.
- On the File menu, click Settings > Snap settings .
- Define the grid spacing intervals in the Spacing boxes.
For example, if the spacing of the x coordinate is 500, you can snap to positions at intervals of 500 units in the x direction.
- If needed, define offsets for the snap grid origin in the Origin boxes.
- To activate the snap grid, select the Active (when free snap is on) check box.
- Click OK.
Now when you pick points using theSnap to any position snap switch, you can only snap to positions at set intervals. The snap grid itself is invisible in the model.
