Changing inclination or perspective

To slant or shear objects, use the red handles located at the midpoint of an edge of

the selected objects. The mouse pointer changes to a when the pointer hovers

over one of these midpoint handles.

Note

In current versions of Draw, basic shapes can be sheared and slanted. The

effect however will probably be different to that obtained when a classic

object has the same slant or shear applied to it, particularly when the

mouse is used to create the effect.

The slant axis is the point directly opposite the midpoint handle to be used for

shearing the object. This point stays fixed in location; the other sides and edges move

in relation to it as the mouse is dragged (make sure that the icon is showing

before dragging).

Figure 43 shows how the vertices move in relation to each other during the shearing

process. The circles represent the path of the vertices. The inclination axis is the

bottom vertex of the triangle (the slanting handle used is the midpoint of the upper

enclosing frame). All points on the figure will move through the same angle

irrespective of the final shape. The actual angle is shown in the status bar.

Figure 43: Shearing an object

Note

The triangle in Figure 43 was produced with the (unfilled) polygon tool

and then Close Object was selected from the context menu.

This tool can be used to produce perspective drawings. The series of pictures in

Figure 44 shows the method of constructing a cuboid or rectangular prism. To

shorten the edges leading from front to back, reduce the length before you distort the

height or width of the surface.

As with rotation, you can make the slanting occur in steps of 15° by pressing the

Shift key while moving the handle.
