2.18.7 The “Concrete slab” tool in Tekla Structures
The “Concrete slab” tool is completely similar to the “Steel
plate” tool. Employing this tool it is possible to model any concrete
volumes, slabs, and wall panels. If the “Concrete beam”
tool allows creating a segment of a defined profile, then the “Concrete
slab” tool establishes a polygon shape object of a definite thickness.

Let’s create a polygon with dimensions of 1000*2000*200 and the
Enable the “Concrete Slab” tool.
Fix out all the polygon forming points at the view.
Upon indicating all the necessary points, press the mouse wheel button
or the “Space” key to finalize the operation.
Press the Esc button to disable the “Concrete Slab” tool.

Let’s create a foundation slab in the current model. For this proceed
Go to the "Views List" window by pressing the Ctrl+I hotkey
combination.
Select the view at the +0,000 elevation point.
Maximize the selected view.

According to the below scheme, unite the extreme points of the model.
Compare your results to the below:

Select the extreme left point of the foundation's polygon slab.
By executing a double-click on it, go to the "Chamfer properties"
menu.
Configure the chamfer type as “Arc point”.

Likewise, proceed to the extreme right point of the foundation slab. Here
we might face the situation when rounding does not work out. This
is one of the Tekla Structures specific features which does not allow rounding
more than one point of a slab with dimensions over 2000 mm. Let’s
investigate the case, though it is not the one frequently occurring, as
such sizable objects usually are not due to rounding.

Let’s examine the bug, by creating two squares with dimensions:

Select all the eight points of the squares, and configure the "Chamfer
type" to “Arc point”.
Tekla Structures v21.1
Tekla Structures v2021
As we can see the 2000 mm face square could not get rounded correctly
at all the points. However, in the current model, we have to create rounding
bilaterally, but the slab polygon dimensions are over 2000 mm.
