Create shapes

In addition to importing item shapes or downloading them from Tekla Warehouseservice for collaboration and for storing and sharing Tekla Structures content

In Tekla Warehouse the content items are stored in collections. Tekla Warehouse includes the Tekla Warehouse Service and the Tekla Warehouse web site.

Tekla Warehouse is one of the Tekla Online services.

, you can create shapes using existing geometry and parts in Tekla Structures models. For example, you can create a shape using a single part or several parts that have been attached to each other.

The part reference pointpoint that Tekla Structures creates when the user creates a model object, the point being visualized as a handle

The reference points follow the model object if it is moved. They are only deleted if the related model object is deleted.

Reference points can be selected as snap points in a snap switch.

that has the yellow handle determines the origin of the shape. The positive global x direction determines the direction of the shape. Later on when you create items using the shape, the shape origin and direction will align with the yellow and magenta item handles.

The shape name is generated using the part name and part location in the format <gridmodeling aid that represents a three-dimensional complex of intersecting grid planes or intersecting grid planes and curved grid surfaces

The grid is defined by coordinates in 3D space. It is shown two-dimensionally on the view plane by dash-and-dot lines. A grid can be rectangular or radial.

It is possible to have more than one grid in a model. For example, a large-scale grid for the entire structure, and smaller grids for some detailed sections.

It is also possible to show grids and grid line labels in drawings, and to modify how they are shown in the drawings.

location>_<elevation>_<part name>. For example:

  • 1/D_+0_FOOTING

  • 3/C_+0-+3600_COLUMN

  • 1-2/A-B_+3600_SLABplate that represents a concrete structure

    In Tekla Structures, a slab is created by picking three or more points.

    Slab may be part of a floor, for example.

If there is already a shape with the same name in the shape catalogcatalog that displays information of item shapes

The shapes are downloaded from Tekla Warehouse, are created using existing geometry and parts in the model, or are modeled using software other than Tekla Structures, for example SketchUp.

, Tekla Structures adds two underscore characters and a running number at the end of the new shape name. For example, 1/D_+0_FOOTING__1.

Create a shape by using existing geometry in the model

Use this method if you want to create a new shape using an existing part, but you do not want to delete the part or change it to an item.

  1. Using parts, model the geometry from which you want to create a shape.
  2. If you want to include more than one part in the shape, attach the parts to each other.
  3. On the Edit tab, click Create shape from geometry.
  4. Select the part.

    Alternatively, you can first select the part, right-click, and then select Create shape from geometry.

Tekla Structures adds a new shape to the shape catalog.

You can then use the shape when you create items in the model. You can also modify items and shapes further in the Geometry editing mode.

Create a shape by converting a part to an item

When you change an existing part in the model to an item, Tekla Structures also creates a new shape and adds it to the shape cataloguser interface for displaying or modifying information in categorized lists

For example, profile catalog and shape catalog are catalogs.


When you change a part to an item, Tekla Structures deletes the original part and replaces it with the newly created item in the model. The name, material, finish, classpart property that groups parts according to identifiers given by the user

The identifiers of classes are usually numbers. Classes can be used for defining the color of parts in the model, for example. Class does not influence the numbering of model objects.

, pour phasepart property that defines which cast-in-place concrete parts form a pour object

Pour phase can be used to prevent cast-in-place concrete parts from merging into one pour object.

, and the 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.

properties of the original part are saved as the corresponding item properties. Other part type specific properties and user-defined attributes are not saved. The objects that are attached to the original part, such as reinforcement and surfaces, are deleted.

  1. Create the parts that you want to change to an item.
  2. If you want to include more than one part in the item, attach the parts to each other.
  3. On the Edit tab, click Convert part to item.
  4. Select the part.

    Alternatively, you can first select the part, right-click, and then select Convert part to item.

Tekla Structures changes the part to an item and adds a new shape to the shape catalog.
