Reference model and base point improvements

Reference model and base point improvements

Reference models now use customizable comparison sets in change detection. There are some new controls making the comparison, change detection, and conversion management more fluent and extensive. In conversions management, the object typedescription of a group of objects that share common characteristics

The objects are grouped based on different characteristics in models and in drawings. Examples of model object types are beams and rebar sets. Examples of drawing object types are parts and marks.

is now visible in the changes list. There are also some improvements in general reference modelmodel which the designer can use as an aid when building another model

A reference model is created in Tekla Structures or in other software and can be inserted to Tekla Structures. The reference model appears together with the model but it is not modified by Tekla Structures. The user can snap to reference model points.

For example, an architectural model, a plant design model, or a heating, ventilating, and air-conditioning (HVAC) model can be a reference model.

handling and base pointpoint in a model that is used to define a starting point in surveying and that is used as an anchor point in coordinate and height transformations

A Tekla Structures project can have several base points but only one of them can be the project base point.

Base points allow the use of another coordinate system needed for interoperability and collaboration. Base points can also be used in drawings, and in reports and templates. Model origin is the default base point in Tekla Structures.

Base points are also called control points.

Improvements in reference model change detection

Comparison sets

  • Change detection in Tekla Structures now compares different versions of the reference model based on a comparison setset of object properties that are used for detecting changes in reference models

    Tekla Structures compares different versions of the reference model based on a comparison set, which tells if a change in a property is considered a change.

    , which tells you whether Tekla Structures considers a change in a property a change or not. You can use the standard property comparison set, or define comparison sets of your own.

  • In the reference model, when the change detection is active, the changes list shows all deleted, changed, new and not changed objects. The property details list only contains those properties that are defined to be compared by the current comparison set rules.

  • To create a new comparison set , in the Change detection section, clickComparison sets to open the Comparison sets dialog box. Add new rules by clickingAdd row , activate/deactivate fixed rules, enter a name for the set, and clickSave.

  • You can also copy and paste properties from the property details list.
  • If you decide that you do not need a comparison set, select it from the list and clickDelete. You can also delete individual rules that you have created by clickingDelete row.

Other improvements in reference model change detection

  • There is now a new This model is newer check box in front of the file path in change detection. Select this check box to define that the file shown in the file path box is newer than the other compared file. If the file has been updated, it appears in the box automatically and the check box is selected.

  • It is now possible to compare as newer (default) or older.
  • New columns Material , GUID and Profile were added in the changes list, and the ID column was removed.
  • You now have a new check box Get selected from the model. When you select it, and click an object in the model, Tekla Structures finds the object row in the changes list, sets the focus on that row, and shows the details list for the selected object.
  • You can zoom to deleted objects in change detection using the Zoom to selected check box. The Zoom to selected check box is disabled if the Select objects in the model is not selected.

  • The older state of a reference model objectmodel object that is an individual part of an imported reference model

    The user can define user-defined attributes for a reference model object.

    The reference model objects can be moved to a model that is currently being worked on.

    Information included in a reference model object can be saved in the model database.

    is now drawn to the 3D viewview that displays objects three-dimensionally

    3D view is one of the default views.

    in orange color when you select the corresponding object.

Improvements in reference model conversion management

  • Selecting a reference model objectobject that is represented in a model

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

    in conversion management changes list also selects the related native object in the model. Now you can more easily modify model object propertiesproperties associated with an object type

    Usually a single object property includes a default value that the user can modify.

    , and use Get to get part properties, or Inquire parts, for example.
  • You now have a new check box Get selected from the model. When you select the Get selected from the model check box, and click an object in the model, Tekla Structures finds the object row in the changes list, sets the focus on that row, and shows the details list for the selected object.
  • The IFCfile format commonly used in BIM that facilitates software interoperability

    IFC is an open specification developed by the IAI (International Alliance for Interoperability).

    Model can be exported into an IFC file.

    conversion management changes list now shows the IFC object type:

    • B-reps are shown as Surface geometry.

    • Arbitrary shapes are shown as Arbitrary. Assembly is also Arbitrary , as well as reference objects that you select using the Select objects in assemblies or Select objects in components selection switches.

    • Parametric profiles are shown as Parametric.

    • The object type is also included in Inquire reports:

New macros for selecting converted or corresponding objects

There are two new macros available for selecting objects: SelectConvertedObjectsBasedOnIfcObjectsSelection for selecting the converted objects, and SelectCorrespondingObjectsBasedOnIfcObjectsSelection for selecting the corresponding objects.

The new macros are located in the Applications group of the Applications & components cataloguser interface for displaying or modifying information in categorized lists

For example, profile catalog and shape catalog are catalogs.

.

  • SelectConvertedObjectsBasedOnIfcObjectsSelection

    In conversion management, this macrosaved series of actions that includes instructions for a program

    Macros are located in the applications and components catalog. They are recorded or created manually and stored as .cs file in a folder defined with the advanced option XS_MACRO_DIRECTORY.

    Macros can, for example, be used for creating drawings or reports.

    Macros are sometimes used to run an application.

    selects the objects that have been converted to native Tekla Structures objects. You may need to select the converted objects to check the properties of the native Tekla Structures objects, for example.

  • SelectCorrespondingObjectsBasedOnIfcObjectsSelection

    This macro is useful in change detection for cases where you exported native objects to IFC, inserted the IFC model back to the same native model, and then you want to select the corresponding Tekla Structures objects. You may need to select the corresponding Tekla Structures objects when you want to add your own UDAs to all updated and selected native objects, for example.

Other improvements in reference model handling

  • In the Add model dialog box and reference model details, you can now pick the Rotation. Previously you had to type the value in the box.
  • Dragging and dropping reference models between groups has been improved.
  • The eye button in Reference models list is now disabled if there are no models in the reference model group.

  • Now you can also refresh locked reference models with the Refresh button. To do this, set the new advanced option XS_REFRESH_ALSO_LOCKED_REFERENCE_MODELS to TRUE in File > Settings > Advanced options > Import. This system-specific option is by default set to FALSE.
  • Performance is improved for those IFC reference models that use instancing, and inserting components with shared definitions, such as windows, furniture, and flow segment terminals is now faster.

Improvements in project base point functionality

  • In the Base point dialog box, you can now pick Angle to North. Previously you had to type a value in the box.

  • The base point location in the model changes according to the location or rotation changes you make in the Base point dialog box when you press Enter or click another input field. Earlier you needed to click Modify.
