The first method for adding/deleting points
This method allows adding/deleting a point by specifying the points interval
Point two can be inserted to any place on the condition that the new contour
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”
Create a simple contour plate (refer to the below picture).
Select the plate and enable the “Modify polygon shape” tool.
The scheme for adding new points to an already existing points range:
Exercise creating several points at the bottom side of the polygon .
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
Thus all the points of the range will get removed.
Exercise deleting the points from the bottom side of the plate.
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”
Enable the tool, thus when selecting the contour plate, its real points
Dragging the midpoints by the mouse cursor turns them into real points.
Drag a point by using the mouse cursor as it is shown below:
Releasing the mouse button executes point displacement and the polygon
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.
The polygon changed its shape to as presented in the below picture:
Deleting a point in the “Direct modification” mode is done
by a simple selection of the point and pressing the “Delete”
Deleting a point bounds the polygon side between the adjacent angular
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.
