2. Right-click and select Explode.
Tekla Structures explodes the plug-in into base objects that are added to the view. Now you
can edit and use the exploded objects as any other drawing objects through the properties
dialog box.
4.11 Welds in drawings
Tekla Structures shows the welds that you have added in a model as weld seams and weld
marks in drawings. You can also add manual weld marks separately in an open drawing.
To change model welds in the drawing, you need to modify the weld in the model. When you
update the model, the weld objects and weld marks are updated in the drawings. In drawings,
you can modify the visibility and appearance of model weld objects and marks.

Weld concepts
Model welds are displayed as weld marks and welds or weld seams in drawings. Welds and
weld marks can be controlled separately. For example, you may want to show the welds in
one drawing view and the weld marks in another.
You can also add weld marks in an open drawing using the Add Weld Mark command.
The weld symbols inside the weld marks indicate the weld properties defined for the model
weld in the model or for the drawing weld mark in the drawing. Below is an example of a
model weld seam (in red) and a model weld mark (in green) in a drawing.

Welds in drawings
In addition to the weld symbols, the weld mark contains a reference line and an arrow. The
arrow connects the reference line to the arrow side of a connection. The welds on the arrow
and other sides of a part can have different weld properties.
When parts are welded together, you can place welds on:
•
The arrow sides only
•
The other sides only
•
Both the arrow and other sides
The following images describe the basic placement principles of welds.
1. Above line
2. Below line

3. Arrow side for weld
4. Other side for weld
By default Tekla Structures places the welds above line according to the ISO standard. You
can change this to below line to comply with the AISC standard with the advanced option
XS_AISC_WELD_MARK.

Example 1 In this example, the first image below shows an example of the Weld Properties dialog box
in the model. You can add welds in the model by selecting one of the welding commands
from Detailing --> Welds . Some of the weld properties are numbered in the dialog box, and
the second image shows how these properties are shown in a weld mark in a drawing. The
same numbers as in the dialog box are used in the weld mark to indicate the position and
appearance of the property information in the weld.

Modifying model weld mark visibility and appearance in a drawing
You can select the welding properties that you want to show in model weld marks in
drawings and adjust the appearance of model weld marks in the Welding Mark Properties
dialog box.
To select which model weld properties to show and to modify the weld mark properties on
drawing view level:
1. In an open drawing, double-click a view frame to open the View Properties dialog box.
2. Click Weld mark to open the View Welding Mark Properties dialog box.
3. Select whether to show the weld number.
4. Under Visibility:
•
Select the views where you want to show the weld marks.
•
Select what kind of welds to show, or whether to hide all welds.
•
Enter a weld size limit to filter welds of that size out of the drawing.
5. Under Above line, Below line and Other, delete the check mark from the Visibility check
box next to a weld mark property that you want to hide.
Remember that if you hide Size, also Prefix is hidden, and when you hide Length, also
Pitch is hidden.
6. To adjust the placing properties, click Place.
7. Click Modify.
8. Go to the Appearance tab and modify the weld mark text and line appearance.
9. Click Modify.
To open the Welding Mark Properties dialog box on the object level, double click the
model weld mark in an open drawing.
Example The first example shows the original weld mark where a lot of properties are visible.

In the second example, all other welding mark properties are hidden, except Type from Above
line and Below line, and Reference text from Other.

Modifying model weld appearance
You can modify the model weld object appearance on drawing level, drawing view level and
drawing object level.
To modify the model weld object appearance on object level:
1. In an open drawing, double-click the model weld seam.
It is easier to select the model weld, if you have only the Select drawing welds selection
switch
selected.
2. Modify the color of the weld.
3. Modify the weld line type.
4. Click Modify.
You can modify the properties of model weld objects on view level by double-clicking
frame of the drawing view containing the weld objects and selecting Welds.

Dragging weld marks
You can drag the model welds by the base point of the weld mark leader line along the weld
seam. This way you can position the weld marks more optimally for increased clarity in the
drawings.
Turn on Smart Select ( Tools --> Options --> Smart Select ), this makes
selecting the leader line base point much easier.
To drag model weld marks:
1. Click the weld mark near the leader line base point.
2. Hold down the left mouse button and drag the base point to a new location by the leader
line base point handle located in the tip of the arrow.

Limitations You cannot drag the leader base point to the back-side of a double-sided weld.
Example The first image below shows the welds in the model.
The second image shows the model weld marks in a drawing. The area within which the weld
mark leader line base point can be dragged is indicated with dark green.

Adding weld marks
A weld mark is an associative annotation object that contains a set of weld properties. You
can define automatic weld marks when you create the drawing, and also add additional weld
marks in the drawing. Tekla Structures creates manual weld marks using the properties in the
Weld Mark Properties dialog box.
To add weld marks:
1. Hold down Shift and click Annotating --> Add Weld Mark to open the Weld Mark
Properties dialog box.
2. Enter or modify the content and the appearance of the weld mark.
To exactly place the weld mark in the position you pick and keep it there, click the
Place... button and select fixed in the Placing list.

3. Click Apply or OK to save the properties.
4. Pick a position for the weld mark.
You can drag the drawing weld mark freely to a more suitable location by the leader base
point handle.
