Snap to a point or line

Snap to a point or line

Most commands ask you to pick points to place objects in the model or drawing. This is called snapping. When you are creating a new object, Tekla Structures displays snap symbols for the available snap points and displays a green line between the snap pointpoint to which Tekla Structures snaps

and the last point picked. Use the snap switches to control which positions you can snap to.

Tekla Structures displays snap dimensions to help you create objects of a desired length. Use the advanced option XS_DISPLAY_DIMENSIONS_WHEN_CREATING_OBJECTS to switch the snap dimensions on or off.

Snap to a line

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 modeling objects that should be lined up with an existing object or a grid linesingle line that visualizes a single grid plane on a view plane

.

  1. Ensure that theSnap to line snap switch is active.
  2. 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 nearby object, Tekla Structures automatically picks both ends of the line. The yellow arrow symbol indicates the direction of the points.

  3. To switch direction, move the mouse pointer closer to the opposite end of the line.
  4. Click the left mouse button to confirm the snap position.

    Tekla Structures creates the object. For example:

Snap to extension lines

You can snap to the extension lines of nearby objects. This can be useful, for example, when you want to align objects with one another.

  1. Ensure that the correct snap switches are active:
    • Switch onSnap to extension lines

    • Switch on eitherSnap to intersection points orSnap to nearest points if you are snapping to the intersection of an extension line(1) temporary line in a model that can be used for aligning objects with each other

      (1) Extension lines can be used when snapping or creating points.

      (2) line in a drawing that is perpendicular to a dimension line and that connects the dimension line to the building object

      and a grid line

    • Switch offSnap to end points if you are working in 3D

  2. Run a command that requires you to pick points.

    For example, start creating 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.

    .

  3. Move the mouse pointer close to nearby objects to see the extension lines.

    When a line is found, you can move the pointer further away while keeping the snap.

  4. Pick the rest of the points.

    Tekla Structures creates the object:

Snap to orthogonal points

Use the Ortho tool to snap to the closest orthogonalview projection that displays objects in right-angles projection

In 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.

point on the plane (0, 45, 90, 135, 180 degrees, and so on). The mouse pointer automatically snaps to positions at even distances in the given direction. This can be useful, for example, if you need to place marks in a consistent manner in exact locations in a drawing.

  1. On the File menu, click Settings and select the Ortho check box.

    Alternatively, you can press O.

  2. Run a command that requires you to pick points.

    For example, start creating a beam. Tekla Structures displays an angle symbol to indicate the direction of snapping. The snapping precision depends on the current zoom level.

  3. Click the left mouse button to confirm the snap position.

    Tekla Structures creates the object. For example:

Snap relative to previously picked points

When you create objects that require you to pick more than two points, you can snap in orthogonal directions relative to the two previously picked points. This can be useful, for example, if you need to create a rectangular slab that is on the view planeplane in a space that defines the view

In Tekla Structures, the grids are projected onto the view plane and the grid lines can be visible on it.

View depth is defined starting from the view plane.

but not along the x and y axes.

  1. Run a command that requires you to pick multiple points. For example, start creating a polybeampart of a certain shape that is created as a continuous chain of beams passing through points that the user picks

    The segments of the polybeam are straight, but segment intersections can be curved. For example, a beam that follows a zigzag line is a polybeam.

    or a rectangular slab.
  2. Pick the first two points.

    Tekla Structures displays an angle symbol to indicate the direction of snapping.

  3. Move the mouse pointer in the model to see the angle symbol.

    When the snap is orthogonal to 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.

    , the color of the angle symbol is green:

    When the snap is orthogonal to the previous points, the color of the angle symbol changes to yellow:

  4. Pick the rest of the points.

    Tekla Structures creates the object. For example:

Create a temporary reference point

You can create a temporary reference pointpoint that Tekla Structures creates when the user creates a model object, the point being visualized as a handle

The reference points follow the model object if it is moved. They are only deleted if the related model object is deleted.

Reference points can be selected as snap points in a snap switch.

to use as a local origin when snapping in models and drawings.

  1. Run a command that requires you to pick points.

    For example, start creating a beam.

  2. Pick the start point.

  3. Hold down the Ctrl key and pick a position.

    A green cross indicates that this position is now a temporary reference point.

  4. Repeat step 3 to create as many reference points as needed.
  5. Release the Ctrl key and pick the end point.

    Tekla Structures creates the object between the start point and the end point. For example:

Lock X, Y, or Z coordinate

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.

  1. Run a command that requires you to pick positions.

    For example, start creating a beam.

  2. 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.

  3. To unlock the coordinate, press the same letter ( X , Y , or Z ) again.
