Improvements in geometry editing and items

Improvements in geometry editing and items

Tekla Structures 2020 introduces new ways to start geometry editing, to add and show item vertexes, and to create items and shapes using existing parts in the model.

When Direct modification is active, just select an item that has a solid shape, and the Geometry editing tab appears at the right end of the ribbon. Previously, you needed to use Quick Launch.

The Geometry editing tab has two new buttons:

  • Click the Handles button to display handles for the selected item. You can then start modifying the item geometry by moving faces, edges, and vertexes.

  • Click the Point button to add new vertexes to the selected item.

If you select a vertex, Tekla Structures now shows the absolute, 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.

coordinates of the vertex in the model views using the Units and decimals settings. For example:

The Cancel button that was previously available on the Geometry editing tab has been removed. The Enter geometry editing mode command has also been removed from Quick Launch.

 

Convert parts to items

You can now change existing parts in the model to items. When you do this, Tekla Structures also automatically creates a new shape for each item and adds the shapes to 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.

.

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.

Curved beams, spiral beams, bent plates, lofted plates, and lofted slabs cannot be changed to items.

To convert a part to an item:

  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. Select the part.
  4. Right-click and select Convert part to item.

    Alternatively, you can go to Quick Launch, search for and select the Convert part to item command, and then select the part.

Tekla Structures changes the part to an item and adds a new shape to the shape catalog. 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 cataloguser interface for displaying or modifying information in categorized lists

For example, profile catalog and shape catalog are catalogs.

, 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.
