 Command line: STRETCH

Select the objects to stretch, then press Enter to confirm or Esc to delete....:

Enter WPOLYGON to define a polygon to be entered.
The example shows a polygon used to select only a part of the image.

Here is a preview of the selection before the STRETCH:

Now, the stretching phase, helped, in this case, by Smart Polar Snap:

The final result:

 

STRETCH   moves only the vertices and endpoints that lie inside the crossing selection, leaving the outside ones unchanged.

 

Base point

Specify base point or [Displacement] < Displacement>: Specify a base point or enter the displacement coordinates

Specify a second point : Specify a second point or press ENTER to use the previous coordinates as a displacement

Displacement

Specify displacement < last value>: Enter the displacement values for X,Y

If a second point is entered, the objects are stretched as much as the vector distance from the base point to the second point. If ENTER is pressed at the Specify Second Point of Displacement prompt, the first pointis treated as an X,Y displacement.
