Changing Object's Shape
The Transform Panel
The Transform panel is used to adjust the geometric properties of objects. To open the panel, select Modify > Transform… in the main menu.
To transform a selected object, set new values in the dialog. Then click the Apply button.
The dialog saves settings after the last transformation. To apply these settings again, select an object and choose Modify > Transform Again.
In order to restore the default values in the dialog, click the Reset button.
When you change one of the values, an outline displays a new shape or position of the object. In the image below, we moved the object to the right but didn't click Apply so far.
The controls in the Transform panel resemble controls from the Geometry panel.
1 - Scale the width or height. You scale up or down from the current object size. The width and height can be changed independently.
2 - Move the object horizontally or vertically by the specified distance.
3 - Reference point selector. The 9-point selector lets you choose a corner, the middle of any side or the center. The reference point preserves its location when you resize or rotate the object.
4 - The rotation tool.
5 - Shear the object. A transformation that can be done with the left tool can also be performed using the combination of the right tool and rotation. The same applies to the right-hand tool.
6 - Flip the object horizontally.
7 - Flip the object vertically.
8 - Transform each. When multiple objects are selected, you can select whether to apply a transformation to each object individually (checked) or to all of them as if they were a single object (unchecked). For example, two selected objects can rotate around the center of the common bounding box (unchecked), or each can rotate around own center (checked).
9 - Transform a copy of the object. Instead of applying a transformation to the original object, the program creates its copy. Then it transforms the copy. As a result, you will have two objects. This feature can be used to create a series of objects with one or several properties changing.
In the following example, we move the square horizontally and vertically and rotate it at the same time. The Copy objects check box should be selected. To repeat the image shown below, you should apply the transformation using the Transform panel. Then repeat it by calling Modify > Transform Again (Cmd-J) multiple times.
Doing this manually would take much more effort.
