Creating such a geometry requires using the construction geometry objects
to correctly set out the cuts.
Thus firstly create vertical lines and copy them accordingly to the below
scheme.
Proceed the same way to the horizontal lines.

We have already exercised creating cuts in the previous chapter by creating
a plate and adding points to it. This time wll exercise another method,
by applying the “Polygon cut” tool.
Tekla Structures v21.1
Tekla Structures v2021
Select the upper points of the added material shape and move them up at
20 mm by using the Ctrl+M hotkey combination. This is to avoid allocating
the cut line at the edge of the part.
Tekla Structures v21.1
Tekla Structures v2021
Referring to the below picture, select the bottom cut point, and by double-click
on it, go to the “Chamfer properties“ menu and set up
the chamfer type as “Arc point”.

to the bottom side of the initial plate. Before copying, make sure that
the Z-axis is perpendicular to the eye gaze direction, if not, then go
to the view plane.

Let’s add up one more plate with dimensions of 100x100, a thickness
Tekla Structures v21.1
Tekla Structures v2021
By using the construction geometry tools, add a center point at the new
plate. In the main menu bar at the "Construction geometry" tab
find the option: “On line”.
Make sure that in the properties menu the number of points is set out
at 1. Thus between two points, a new point will appear right in the
middle of the defined segment.
Tekla Structures v21.1
Tekla Structures v2021
Press the "Esc" key to deactivate the “Create point on
line” tool. Further, select the point created, and by holding on
the "Shift" key pressed, select the plate as well. Enable the
Ctrl+M hotkey combination and move the objects to the intersection
point of the construction lines.

Let’s create bolt holes in the upper plate.
As you already know, bolted holes in the TS are created using the “Bolt”
Enable the "Bolt" tool and indicate the plate as a single joinable
part, and set out the bolted joint direction by uniting the middle points
of the sides of the yellow plate.

Inquire about the resulting assembly’s main component. For this
purpose select any part, and in the right-click menu, enable the respective
tab. The assembly’s main component is highlighted in orange color.
Tekla Structures v21.1
Tekla Structures v2021
As we have previously discussed, the assembly’s main component shall
be defined by the rolled profile body. In the current case study, it should
be the I-beam body defining the assembly's name and prefix, and ignoring
the respective of the other components included.
It is important to mention that every subsequently created weld reappoints
the main component. To correctly set out the main component it is
required to select the weld, which refers to the main assembly part, or
upon welding on completion, forcefully indicate it.
In the current case, forcefully set out the main component.

Now let’s clarify the yellow plate assignment. The current exercise
represents a field case of a column base, where the column is put at the
concrete and is supported by a plate. During the installation of the column,
the plate bolts are already located into the concrete pour and are sticking
out.
As the set-on accuracy of the bolts of the plate can be insufficient,
with this purpose elongated bolted holes are created. The cuts drawn up
in the initial plate allow shifting the column at the distance to 5 mm
in all the possible directions to certainly install the column to the required
position.
The upper washers (yellow plates) are necessary for preventing bolts
from caving into the elongated holes and are to be welded on after definitively
setting up the column.
This column base type has been taken as an example for the reason that
it requires creating elongated holes, which are generally seldom used,
and are not possible to be established employing the “Bolt''
tool. All the other holes in the model shall be created by using
the “Bolt” tool, otherwise, not respecting this rule is considered
a critical error. Also, the yellow washers are to be welded on in-situ
after the column installment, taking into account the abbe offset value.
Create a polygon weld.

Execute "Copy special/ To another object" of the weld to another
yellow plate.
Select the weld.
Enable the “Copy Special/ To another object” tab in the right-click
menu.
Indicate the initial welded on object.
Subsequently indicate other objects to be welded on.
Tekla Structures v21.1
Tekla Structures v2021
Note that two objects are welded on properly, but the other two are not.
The reason is that the local coordinate systems of plates are completely
identical, and copying the weld seams duplicates their orientation.
Thus for the upper yellow washers, it shall be applied to the mirrored

Tekla Structures v21.1
Tekla Structures v2021
Note that the weld seams and bolted holes are copied along with the plates,
despite the fact we have not selected them and their alignment is correct.
Here we can deduct one more property of welding seams and bolt holes, which
is: copying a welded-on object automatically initiates copying welds associated
with it. It is of high convenience as the user does not need to select
multiple associated objects and thus avoids committing errors by missing
out on any of them.
