Modeling improvements

This version makes modeling easier in several ways. The highlights include improvements in selecting and snapping, several improvements in direct modificationfunction that activates the mode where the model objects can be modified by using handles

Direct modification enables additional handles and modification options.

, and further development that helps you modify the bent plates created using the new bent plate(1) part that is created from contour plates, or beams whose profile is a plate

(1) Bent plates can include conical or cylindrical sections.

(1) Curved beams, spiral beams, or deformed parts cannot be used for creating a bent plate.

(2) component object that represents an angle that is bent from a plate and that connects parts

featurepart of Tekla Structures functionality that is maintained and owned by Trimble Solutions and that is included in the Tekla Structures installation

introduced in Tekla Structures 2016i. We have also revised the help materials on filtering, so if filtering has seemed confusing so far, it may pay off to read through some of the new instructions and examples.

Selecting objects hidden behind other objects

  • You can more easily select objects that are hidden behind other objects. For example, you can select reinforcing bars even if they are hidden behind the surface handle (the yellow area in the image) of a nearby object:

Direct modification improvements

  • In previous versions, you needed to press the Shift key when dragging a direct modification handle to an existing snap pointpoint to which Tekla Structures snaps

    or line. This has been changed so that snapping to points and lines is enabled by default. If you temporarily want to disable snapping to points and lines, press the Shift key.

  • You can move point and line handles to any location in the 3D space by using the new Move in 3D command. The command becomes available on the contextual toolbarfloating toolbar that contains commands for modifying the most common object properties

    The user can customize the contextual toolbar.

    when you select a point or line handle.

  • You can still restrict handle movement if needed. With point handles, you can use the Move in XY plane and Move in Z direction options. With line handles, you can use the Move in parallel direction and Move in perpendicular direction options. In plane views, the handles always stay in 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.

    even if the Move in 3D command is switched on.

  • You can also restrict handle movement to a selected part plane. This can be useful when working with a sloped roof, for example. Click the Move in selected plane button on the contextual toolbar, select a part plane, and then drag the handle to a new location. The handle can be moved in the selected plane only.

    For example:

  • Tekla Structures remembers the snap mode setting ( Move in 3D / XY plane / Z direction / parallel direction / perpendicular direction ) until you close the model.

  • You can now control the visibility of all direct modification dimensions. Click thebutton to show the options, and then click the eye button to show or hide dimensions:

    • X, Y, Z dimensions : All 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.

      dimensions in 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.

      directions X, Y, and Z are displayed.

    • Total dimensions : Only the total length is displayed.

      These visibility options are available for parts, cuts, construction objects, and rebar sets. Tekla Structures remembers the visibility setting when you create or open a new model, or restart Tekla Structures.

  • You can now enter an exact distance when moving a direct modification handle. Drag the handle and type the distance. When you start typing, Tekla Structures displays the Enter a Numeric Location dialog box automatically:

  • Polygon cuts now have a plane handle which can be used for modifying the thickness of the cut:

  • Direct modification is now also available for line cuts :

  • Tekla Structures now tries to keep dimension lines and values in the view even when you zoom in or move the view. Dimensions may be moved to another side of the part, for example:

  • Dimension arrowheads and custom partcomponent for creating a part that cannot be created by using any existing part command or part profile

    Typically, custom parts are used to create parts that have a complex composition. For example, castellated beams and sandwich panels are often created as custom parts.

    placing handles now keep the same size, regardless of the zoom level:

  • Tekla Structures now only shows the dimensions that are relevant in each view. In the following example, the perpendicular (red) dimensions are visible in the previous version of Tekla Structures but hidden in Tekla Structures 2017:

    Part perspective view

    Part end view, Tekla Structures 2016i

    Part end view, Tekla Structures 2017

  • You can now create temporary reference points when creating new objects using direct modification.

New snap settings

General snap settings are now available in File menu > Settings > Snap settings. Previously, these settings were located in the Options dialog box, under Mouse settings.

Also new snap options for the Ortho tool have been added:

Bent plate improvements

Tekla Structures 2017 contains many useful improvements that help you modify the shape of existing bent plates.

  • You can edit the bend radius directly on the contextual toolbar:

  • You can change the shape of the curved section by choosing one of the predefined options:

    Tapered bend

    A gradual decrease in the width between the parts. This is the default option.

    Narrow bend

    Constant width between the parts. The width is determined by the narrowest part.

    Wide bend

    Constant width between the parts. The width is determined by the widest part.

  • Additionally, you can modify and fine-tune the curved section manually by dragging the blue boundary handles:

    For example:

  • You can also change the shape of the flat sections. When you click the green selection handle of the section you want to modify, the direct modification handles of the selected section become visible:

  • You can remove individual curved sections by clicking the Remove bend button on the contextual toolbar. For example:

Custom Inquiry available in side pane

Custom Inquiry is now available in the side pane. Click the button in the side pane to view model objectobject that is represented in a model

A model object is either created in a model or imported into it.

properties using Custom Inquiry.

Alternatively, you can still click the down arrow next toon the ribbon, and then select Custom inquiry.

Custom Inquiry works in the same way as before, only the user interface has been slightly improved.

For more information, see Custom inquiry and How to use the side pane.

Improvements in clash checking

A new clash check setting is now available in File menu > Settings > Options > Clash check.

Use Allowed penetration volume to define an allowed clash check tolerance if small collisions are acceptable and can be ignored. Enter the tolerance in the current volume units.

If the clashing volume in the model is smaller than the given value, for example 1 mm 3 , then the clash is not reported.

New command for showing all detailing of a part

A new command Display detailing is now available for showing all objects and detailing related to a part. For example, you can use this command to examine whether parts are cut or welded correctly.

  1. Select a part.
  2. ClickDisplay detailing on the contextual toolbar.

    Alternatively, you can press Alt+D , or use Quick Launch.

For steel parts, Tekla Structures displays all parts, bolts, welds, cuts, fittings, and other details belonging to the assembly, even if you had defined them as hidden in the display settings. For concrete parts, Tekla Structures displays also reinforcement, surface treatmentbuilding object that represents finishing of a part

The term surface treatment is used in concrete detailing. For concrete parts surface treatment includes surface mixes, tiles, and flat finishes, such as troweling and sandblasting.

The term surface finish is used in steel detailing. For steel parts surface finishes include fire-proofing and unpainted areas.

, and surfaces.

Documentation updates for filtering

The instructions for the filtering functionality have now been revised, as requested by many of our readers. Please note that the functionality itself has not been changed. The instructions now contain detailed information about the various object properties that you can use in filter rules. Also more information on how to use conditions and brackets have been included. All example filters have been checked and improved to contain more complex filter rules, brackets, and so on.
