Better performance and other modeling improvements

Better performance and other modeling improvements

There are many modeling improvements in Tekla Structures 2018i, for example, in items with imported shapes, in model welds, in copying and moving, and in 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.

.

Performance improvements in models with items

Tekla Structures 2018i comes with improvements that enhance performance in models that contain items with imported shapes. For example, the following actions are now faster than previously:

  • Opening models that contain items
  • Opening model views that contain items
  • Creating, moving, and copying items in the model
  • Navigating through the model by panning, zooming, rotating views, etc.
Note:

If your model has been created using an older version of Tekla Structures , it is important that you re-import the shapes to override the existing ones in the shape catalogcatalog that displays a list of predefined item shapes

The shapes are modeled using software other than Tekla Structures, for example SketchUp.

and to gain from these improvements. Re-importing improves both the performance and the quality of the shapes, and reduces the shape geometry file size.

Linking the Above line and Below line property values of welds

In the Weld properties in the property pane, the Above line and Below line properties are now side by side in two columns. You can also link together the Above line and Below line property values, and keep them synchronized when you change values in either of the columns. Previously you needed to modify the values separately.

To copy values from one column to the other, use theandbuttons.

To link together the Above line and Below line property values, or to unlink the values, click the button.

When the values are linked, the middle button is yellow. This means that if you change a value in either of the columns, the corresponding value in the other column also changes.

Special characters in weld reference text

Weld marks in model views are now shown using the Arial font. This means that the special characters in the weld reference text are now shown correctly if the Arial font supports those special characters.

The weld markmark that includes a set of selected property elements related to a weld

is shown in the model viewview that is represented in the modeling mode

Model view is available also in the drawing mode and it is represented in its own window.

when you select a weld and the representationthe way that the information included in a model is represented visually

option for welds is set to Exact.

Improvements in polygon welds

You can now modify one-sided polygon welds using direct modificationfunction that activates the mode where the model objects can be modified by using handles

Direct modification enables additional handles and modification options.

.

Improvements in copying and moving objects

  • When you copy or move objects, Tekla Structures now checks if there already are identical line cuts, polygon cuts, part cuts, fitted part ends, bolts, or welds in the target location, and then warns you about the duplicates. Previously, only parts, reinforcement, and pour breaks were checked for duplicates.

    Tekla Structures also checks for duplicates when you create new cuts, fitted part ends, bolts, or welds in the same location as an existing object.

    However, identical cuts and fitted part ends applied to different parts are not counted as duplicates. So you can cut different parts with polygon cuts that have the same properties and location.

  • Sub-components now move along with their parent object even when the parent object is a component.

Ignoring duplicate bolt holes in part numbering

You can now define whether duplicate bolt holes in the same location, or within a tolerance , in a part are ignored in part numbering.

This is useful when only some and possibly a different set of the holes in otherwise identical parts will be used for bolting on site. In this way identical parts can be used in different conditions in the structure.

Use the new advanced option XS_​BOLT_​DUPLICATE_​IGNORE to define whether the duplicates are ignored ( TRUE ) or not ( FALSE ). The default value is FALSE. Use the new advanced option XS_​BOLT_​DUPLICATE_​TOLERANCE to set the location tolerancepermissible amount by which the dimensions of a structure may vary from the work size specified

Tolerance is usually stated as a plus or minus dimension.

The term ’tolerance’ is used in its general sense in Tekla Structures.

In a model the term ’tolerance’ should not be used to refer to a gap.

that defines which bolt holes are considered duplicates and will therefore be ignored in part numbering.

Changes in numbering settings

In Tekla Structures 2018i, there is now a new advanced option XS_​ENABLE_​PHASE_​OPTION_​IN_​NUMBERING that controls the Phase setting in the Numbering Setup dialog box. This advanced option is model specific and it is available in the Advanced Options dialog box.

When XS_ENABLE_PHASE_OPTION_IN_NUMBERING is set to FALSE (which is the default value), the Phase check box is disabled in the Numbering Setup dialog box. This means that changing an object's phase works in the same way as in Tekla Structures 2017i and earlier versions, and that changing the phase does not affect numbering or trigger change alerts.

If XS_ENABLE_PHASE_OPTION_IN_NUMBERING is set to TRUE , the Phase check box is enabled in the Numbering Setup dialog box. This is the recommended setting for Tekla Model Sharingcloud service for collaboration and for storing and sharing a model

users.

If you select the Phase check box, changing the phase of an assembly (or an assembly main partmain part that exists in an assembly

The assembly main part in a steel assembly may have other parts welded or bolted to it. By default, the assembly main part is not welded or bolted to any other parts.

The user can change the assembly main part.

) affects numbering in the same way as the other settings in the Numbering Setup dialog box. Changing the phase of a secondary part(1) part that exists in a building object and that is connected to the main part

(1) Secondary part can be an assembly secondary part or a cast unit secondary part.

(2) input part that the user selects after selecting the component main part when creating a component

(2) A component can have none, one or more component secondary parts.

does not affect numbering.

Note! Even if you do not select the Phase check box, but you change the phase of an object when XS_ENABLE_PHASE_OPTION_IN_NUMBERING is set to TRUE :

  • A question mark (?) is added to the object's position numberidentifier that is assigned to all similar parts, assemblies, cast units, or reinforcement

    Position number consists of a prefix, separator, and running number. The prefix is part of the position number, identifying a numbering series. The running number is part of the position number, and is the assigned number in the numbering series, based on the start number. The separator is an optional character, such as a slash, that separates the prefix and the running number.

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

    In the US, the term piece mark or ship mark is used to refer to a position number.

    indicating that numbering is needed.
  • After renumbering, the drawing listlist of drawings that provides information about the drawings in a particular model and that is used for searching, managing, and printing the drawings

    In the drawing list, the user can, for example, search, open, update, freeze, lock, and delete drawings. The drawing list can also be used to display the associations between the drawings and the parts in the model.

    indicates that the drawings need updating.
  • In shared models, the Changes list shows the changed parts and assemblies.

This happens even if you are using the Project Viewer configuration.
