When you run a clash check using Tekla Structures 2019i, you can check the model for duplicate and overlapping welds and for clashes that occur between welds and other objects such as parts and bolts.

To do this:

1. Click File menu > Settings > Options to open the Options dialog box.

2. Go to the Clash check settings.

3. In the Exact solid weld clash check list, select Yes.

4. Modify the other clash check settings if needed.

5. Run the clash check.

Tekla Structures checks the welds against other welds, against bolts, and against the real geometry of the part profiles including roundings, and using the weld solid dimensions with normal accuracy.

When you review the clash check results, note that you can now show a new column , Object Type , in the Clash Check Manager dialog box.

Now if a part has a single-part drawing and you modify the part so that it becomes identical to another part, the following things happen when you number the model:

• Both parts receive the number of the unmodified part.

• The drawing is automatically cloned using the original drawing of the modified part as a cloning template. The original drawing is saved with the Quantity decreased comment in the Changes column in Document manager.

  Note that the cloning happens only if the Automatic cloning option is selected in the Numbering Setup dialog box.

Pour resolving speed has been improved. When opening a model that contains pours, the initial pour resolving is now faster than before. This is especially noticeable when opening models containing a large number of pours.

In addition to importing item shapes or downloading them from Tekla Warehouse , you can now 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.

To create a shape, do one of the following:

• Select a part, right-click, and then select Create shape from geometry.

• Go to Quick Launch , search for and select the Create shape from geometry command, and then select a part.

Tekla Structures adds a new shape to the shape catalog using the part name as the shape name.

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 by dragging vertexes, edges, and faces. This gives you an alternative way to model complex structures such as slabs that slope to drains, for example.
