Change the coordinate system

Change the coordinate system

You change the angle from which objects are viewed, how the object is rotated, and how the dimensions in the drawing viewview that includes selected model objects or an area in the model, that is represented in a drawing

A drawing view is a container for model and drawing objects.

A drawing can include several drawing views, which usually are two-dimensional views, plane views, to the model.

Examples of drawing views in Tekla Structures include main views, section views, single-part views, and 3D views.

are oriented.

The coordinate system defines:

  • The angle from which the part, assembly, or cast unit is viewed.

  • How the part, assembly, or cast unit is rotated.

  • The orientation of the dimensions in the drawing view.

To change the coordinate system:

  1. On the Drawings & reports tab, click Drawing properties and select the drawing type.
  2. Load the drawing properties that you want to change.
  3. Click View creation and go to the Attributes tab.

    The settings affect all views in a drawing.

  4. In Coordinate system , select one of the available coordinate systems:
    • local

      Tekla Structures uses the local coordinate systemcoordinate system that reflects the current work plane or drawing view plane

      The local coordinate system is represented in a model by a symbol with three axes (x, y, and z). This symbol indicates the direction of the model. It is located in the lower right corner of the model view.

      In a drawing, the local coordinate system symbol has two axes.

      of the main part(1) part that exists in a building object and that determines the position number for the assembly or cast unit and the direction of assembly or cast unit drawings

      (1) Main part can be an assembly main part or a cast unit main part.

      (2) input part that the user selects first when creating a component

      (2) Connections and details always have a component main part.

      . The x axis of the part is parallel to the x axis of the drawing, and the start point (the end point created first) of the part is on the left. The start point is marked with yellow, and the end point created second is marked with pink.

    • model

      Tekla Structures uses the global coordinate systemcoordinate system that reflects the entire space of a model

      A green cube represents the global coordinate system and lies at the global point of origin in the 3D view.

      . The part has the same position in the drawing as it has in the model. This is one option when you want to show columns vertically. You can also use this option to display sloping parts in position. Tekla Structures cannot display horizontally skewed parts.

    • oriented

      Tekla Structures uses the local coordinate system of the main part, but the coordinate system is oriented so that the x axis of the part points to the right even if the part was created from right to left.

    • horizontal brace

      Tekla Structures automatically rotates the drawing views so that the front viewdefault view that is created using the part’s or component’s coordinate system and that shows the part or component from the front direction

      Part’s front view is a view on part plane created of the part’s front plane.

      is from the top of the model. This is used for skewed braces. It automatically rotates the front view around the x axis.

    • vertical brace

      Tekla Structures automatically rotates the drawing views so that the front view is in the same plane as the brace in the model. This is used for skewed braces. It automatically rotates the front view around the x axis.

    • For concrete parts, the option Fixed rotates the front view so that it shows the casting direction (the face that is top in form) of the concrete part, if it is defined in the model. For more information about the casting direction, see Casting direction

  5. To save the changes, click Save.
  6. Click OK and create the drawing.
