Modeling improvements

Tekla Structures 2017i comes with many important improvements in view creation, direct modificationfunction that activates the mode where the model objects can be modified by using handles

Direct modification enables additional handles and modification options.

, numberingprocess of assigning position numbers to parts, cast units, assemblies, or reinforcement

In Tekla Structures, the position numbers assigned in the numbering are shown in marks and templates, for example.

, and pour management.

Easier way to create views

You can now create model views more easily on 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.

or on existing part planes. Use the new Create view on plane command and select the desired plane. Tekla Structures creates the view accordingly.

Direct modification improvements

  • The standard object dimensions and dimension lines are now hidden when direct modification is on, regardless of the XS_​DISPLAY_​DIMENSIONS_​WHEN_​SELECTING_​OBJECTS advanced option. Only the direct modification dimensions are shown. This makes it easier to know which dimensions can be edited.

  • You can now modify the dimensions of model objects even more quickly. Click a dimension, type a new value, and then press Enter. The dimension changes immediately.

    The yellow arrow defines the direction in which the object is extended or shortened. You can change the direction by clicking the arrows.

New display settings for cast-in-place concrete parts

When the pour management functionality is enabled, you can view cast-in-place concretecast unit type where the concrete is formed, poured, and cured in its final position

structures in model views either as parts or as pour objects. In addition to selecting between parts and pour objects, you can now define how the cast-in-place concrete parts appear in model views.

The Display dialog box now has a new setting Cast in place parts with two options:

  • Merged

    Tekla Structures shows concrete parts as merged in the model if their cast unit typeproperty of a concrete part in a cast unit that defines if the structure type of the part is precast or cast in place

    is cast in place , if they have the same material grade and pour phase number, and if they touch or overlap one another. When these criteria are met, Tekla Structures removes the outlines of the individual parts within each continuous concrete structure.

  • Separated

    Tekla Structures shows concrete parts as individual parts and separated by their outlines.

For more information, see View cast-in-place concrete structures.

Improvements in pour management

  • Pour unit calculation is now faster. When you click Calculate pour units on the Concrete tab, Tekla Structures now attaches objects to pour objects and creates pour units incrementally, which means that only the new and changed objects are re-calculated.
    Note that rebar sets are not handled incrementally, but they are always re-calculated.

  • Pour management has been improved in shared models and in multi-user models.

  • You can now add pour breaks to phases , and then use the phases and the Copy special > From another model command to copy pour breaks between models.

    When you do this, the copied pour breaks adapt to the target model, so remember to check the resulting pour geometry and pour breaks against the original model.

    When you create new pour breaks, they are not added to the current phase, by default.

Improvements in numbering

  • In the Numbering Setup dialog box, you can now select whether the assembly name affects the numbering. If you select the Assembly name check box, Tekla Structures compares the assembly names when numbering objects, and gives otherwise identical assemblies different numbers if they have different names.

    For more information, see Define what affects numbering and Adjust the numbering settings.

  • You can now have the user-defined attributeobject property created by the user in order to widen the range of predefined object properties

    User-defined attributes are used when the predefined object properties are not sufficient but more properties are needed. For example, comment, locked, and erection status are user-defined attributes.

    Fixed drawing main view affect the numbering of non-concrete parts. This user-defined attribute defines which part face is shown in the main (front) view in drawings that have Coordinate system set to Fixed. If parts have different options selected for Fixed drawing main view , they can now get different assembly positionposition number that is assigned to an assembly or a cast unit

    numbers and different drawings.

    Use the advanced option XS_SET_​FIXEDMAINVIEW​_UDA_TO_​AFFECT_​NUMBERING to define which material types have this featurepart of Tekla Structures functionality that is maintained and owned by Trimble Solutions and that is included in the Tekla Structures installation

    . The allowed options are STEEL , TIMBER , and MISC. You can also combine the options by using a comma (,) as a separator.

    See also Changes in advanced options.

  • The position numbers are now kept better when there are conflicts in numbering.

Indicating the drawing main view face of non-concrete parts in the model

With the advanced option XS_SET_​FIXEDMAINVIEW​_UDA_TO_​AFFECT_​NUMBERING set, you can now use the commands Set top-in-form face and Show top-in-form face also for non-concrete parts that have an option selected for the Fixed drawing main view user-defined attribute.

The commands Set top-in-form face and Show top-in-form face are available on the Concrete tab under Cast unit. Note that you need to use the Parts rendered ( Ctrl+4 ) renderingprocess of making the model object faces visible

The rendered model object faces can be transparent or non-transparent

option when you use these commands.

For more information, see Casting direction and Select the steel or timber part face that is shown in front drawing view.

Increased polygon point limit

You can now create plates, slabs, polybeams, and strip footings that contain more than 100 polygon points. The new maximum number of polygon points is 1000 for parts and bolt groups, and 999 for profile cross sections.
