2.6.7 Adding and deleting points at/from the contour plate in Tekla Structures
Adding points
The first method for adding/deleting points
This method allows adding/deleting a point by specifying the points interval
Tekla Structures v21.1
Tekla Structures v2020
Point two can be inserted to any place on the condition that the new contour
Tekla Structures v21.1
Tekla Structures v2020
If a new contour does not possess the right building-up trajectory of

Setting the “Modify polygon shape” icon at the main menu tab
By default, the “Modify polygon shape” icon is not located
Therefore go to the “File”, “Settings”, “Ribbon”
Tekla Structures v21.1
Tekla Structures v2021
Create a simple contour plate (refer to the below picture).
Tekla Structures v21.1
Tekla Structures v2021
Select the plate and enable the “Modify polygon shape” tool.
Tekla Structures v21.1
Tekla Structures v2021
The scheme for adding new points to an already existing points range:
Tekla Structures v21.1
Tekla Structures v2020
Select the contour plate.
Activate the “Modify polygon shape” tool.
Select the first point of the range to where the new point will be inserted
(marked by 1 in the scheme).
Identify the new position of the point in the range (marked by 2 in the
scheme).
By a double left-click specify the second point in the range (marked 3,4
in the scheme).
Tekla Structures v21.1
Tekla Structures v2021
Exercise creating several points at the bottom side of the polygon .
Tekla Structures v21.1
Tekla Structures v2021
To delete a point/ a group of points
apply the same tool in the following way: choose the points that form
the range from where the other points will get deleted (marked by 1 and
2,3).
Thus all the points of the range will get removed.
Tekla Structures v21.1
Tekla Structures v2020
Exercise deleting the points from the bottom side of the plate.
Tekla Structures v21.1
Tekla Structures v2021
Exercise this method for adding and deleting points on your own.
The 2nd method for adding /deleting a point
is executed by using the “Direct modification tool”
(v2021
,v21.1
).
Enable the tool, thus when selecting the contour plate, its real points
Dragging the midpoints by the mouse cursor turns them into real points.
Tekla Structures v21.1
Tekla Structures v2021
Drag a point by using the mouse cursor as it is shown below:
Tekla Structures v21.1
Tekla Structures v2021
Releasing the mouse button executes point displacement and the polygon
Tekla Structures v21.1
Tekla Structures v2021
Note that in the range between the new point and the polygon angular point
a new imaginary midpoint appeared. Let’s drag an imaginary
point as it is shown below.
Pay attention to the displacement amplitude by axes X and Y.
Tekla Structures v21.1
Tekla Structures v2021
The polygon changed its shape to as presented in the below picture:
Tekla Structures v21.1
Tekla Structures v2021
Deleting a point in the “Direct modification” mode is done
by a simple selection of the point and pressing the “Delete”
key.
Tekla Structures v21.1
Tekla Structures v2021
Deleting a point bounds the polygon side between the adjacent angular
Tekla Structures v21.1
Tekla Structures v2021
To move a side of a polygon proceed as follows: select the side and displace

Changing the thickness value of a plate.
Rotate the view in the way to see the plate’s thickness. Select
the plate and displace it at a required distance by the mouse cursor. Thus
we are changing the plate's thickness.
This method is useful for illustrative purposes, though in practice it
is not used, thus please switch off the “Direct modification”
tool to avoid any accidental and unwanted updates.

Hereunder you can see the plate with the modified thickness value.
