In the group Teapot Parts (Части чайника) whip off a small flag at some parameter, watching a result. Then will set small flags again or will cancel action a command Undo (Отмена) .
You will move a tea-pot in accordance with a fig. 1.1.
To obtain complete accordance with a picture, it is necessary to turn an object. For this purpose:
Click on a tea-pot the right mouse button, choose
in a context menu a command Rotate
(Вращение) or push the button
Rotate

of object, an axis here will change a color on yellow, after, pushing
the left mouse button, move it, watching testimonies in a status line
at the bottom of screen (fig. 1.3).

Parallelepiped with the smoothed out verges
Push the button ChamferBox . Create in a projection window Top (Вид сверху) parallelepiped.
You will set parameters:
Length (Длина) - 53
Width (Ширина) - 56
Height (Высота) - 18
Fillet (Скругление) - 2,5
You will move and turn him in accordance with a fig. 1.1.
Cylinder
Push the button Cylinder
(Цилиндр)
.
Create a cylinder in the projection window Top
(Вид сверху).
You will set parameters:
Radius (Радиус) - 20
Height (Высота) - 27
Height Segments (Сегменты высоты) - 1
You will move a cylinder in accordance with a fig. 1.1.
Sphere
Push the button Sphere
(сфера)
.
Create a sphere in the projection window Top
(Вид сверху)
in the middle cylinder.
You will set the parameter Radius (Радиус) equal 13.
You will move a sphere in accordance with a fig. 1.1.
Star
Push the button Hedra
.
Create a star in the projection window Top
(Вид сверху).
You will set the small flag Star (Звезда) in the part Family.
You will set the parameter Radius (Радиус) equal 18.
You will move a star in accordance with a fig. 1.1.
You will save a file in a buffer. Choose a command Hold (Держать) the menu Edit (Редактирование).
Note
To the work stage, stored by such method (Edit, Hold), it is possible to return, choosing a command Fetch (Вызвать) the menu Edit (Редактирование).
Smoothing of objects
This operation is executed by means of instrument Align (Выравнивание).
At first we will locate all objects on the surface of the first parallelepiped:
In the right bottom corner of screen, in the
section of the buttons of management specific screens, push the
button Zoom Extents All
(Показать все
предметы)
.
In the projection window Front (Вид спереди), represented on a fig. 1.4, will take all objects which must be placed on the surface of parallelepiped (created by the first, fig. 1.1).

1.4. Selection of group of objects an area
Remark
Objects in a group it is possible to add or take away the click of the left mouse button on an object at the pushed-in key.

Remark
If to detain a cursor on an object, then its name will appear. After a click the window of setting of smoothing appears on an object. In the group Current Object (Текущий объект) window Align Position (Screen) (Выровнять позицию), shown on a fig. 1.5, will set the switch Minimum (Минимум) - on the bottom edge of the evened object. In the group Target Object (Целевой объект) will set the switch Maximum (максимум) - on the overhead edge of object. You will set the small flag Y Position (Выравнивание по оси Y). Push the button OK.

Smoothing of tube on the center of torus
You will be commuted on the toolbar Main

or press the key <H>. In an appearing
window choose from the list of objects of the stage Tube01,

In the group Current Object (Текущий объект) of the windows Align Position (Screen) (Выровнять позицию) choose switch Center (Центр), in the group Target Object (Целевой объект) also will set the switch Center (Центр). You will set small flags on the axis of smoothing X and Z (at the active screen Front). Push the button OK.
Remark
Because the system of coordinates by default is determined on the projection of specific screen Screen (fig. 1.6), smoothing axes depend on that, what screen is active presently. To avoid dependence on the choice of projection window, it is possible to be commuted on other coordinates determination system, for example, Local (Локальная).
