Parallelepiped by a point and three dimensions
The Parallelepiped by point and three dimensions 
command. is used to construct a parallelepiped by a point and three dimensions.
Step-by-step instructions
1.Select the Operation Result, by clicking the appropriate button in the Result group on the Parameters Toolbar:
Merging,
New solid,
Subtraction,
Intersection.
For the options Merging, Subtraction, and Intersection, you can configure operation application area In the section Application Area.
2.A phantom of the parallelepiped with the base element 
is displayed in the graphic area.
Specify which point in the lower base of the parallelepiped will be the reference point by clicking the desired button in the group Base Point:
Vertex,
The center of the edge,
Middle of the rib.
3.Set the position of the reference point of the parallelepiped in the group Position and the orientation of the axes of its coordinate system in the group Orientation. These actions are similar to the positioning of the LCS in the model and are described in detail in the sections LCS position and LCS orientation.
You can change position of an object In the graphic area using a base element.
The position of the parallelepiped can also be specified by indicating a plane or flat face in the Design Tree or in the graphic area. In this case, the reference point is constructed at the place of the object's specification. In the field Snap Point, the method of point construction is displayed as On Surface. The Z axis is perpendicular to the specified face/plane. An associative link is formed between the selected object and the parallelepiped, due to which the parallelepiped will follow the object when its position is changed.
4.Specify the length and width of the parallelepiped in the fields Length and Width. Negative values can be entered. A negative value changes the direction of the length or width measurement to the opposite.
The calculation direction of the value can also be changed to the opposite by clicking the Change direction button 
to the right of the required field. The button is present depending on the selected option in the group Base Point: if the option Vertex is selected, the button is present for both length and width; if the option Middle of the rib – only for length, and if the option The center of the edge, the button is absent.
5.Set the height of the parallelepiped in the element group Height.
Height can be offset in one direction or in two opposite directions. The method to specify height is selected using the group of buttons Method . Parameters for the selected method are set in the same way as when you build extrusion elements, with one exception: when creating a parallelepiped, there is no method to specify the height to the nearest surface.

6.Click the Create Object 
button to complete the construction.
7.To complete operation of the command, click the Finish 
.
After plotting is completed, a parallelepiped will appear in the model, and its icon will appear in the Construction Tree .
Additional parameters of elementary bodies
Parallelepiped by two points and height
To construct a parallelepiped by two points and height, the Parallelepiped by two points and height 
command. is used.
Step-by-step instructions
1.Select the Operation Result, by clicking the necessary button in the Result group on the Parameter Panel:
Merging,
New solid,
Subtraction,
Intersection.
For the options Merging, Subtraction, and Intersection, you can configure. operation application area In section Application area.
2.Specify the start and end points of the diagonal in the base of the parallelepiped using the element groups The first point (1) and The second point (2). The starting point of the diagonal is the reference point of the parallelepiped, with which the location element coincides. The base of the parallelepiped lies in the XY plane of the element. If the end point of the diagonal is specified outside the XY plane, then it is projected onto this plane.
The following methods can be used for configuring the point position:
•Indicate the point position with the mouse in the graphic range.
•Enter coordinates in the Coordinates field.
•Select a point object or a flat face/plane in the Design Tree or in the graphic area. The name of the object appears in the Snap point field.
If a flat face/plane is specified, the point is constructed at the location of the object's specification. In the field Snap point the method of point construction is displayed — On Surface. The Z axis is perpendicular to the specified face/plane.
An associative link is formed between the selected object and the parallelepiped, thanks to which the point of the parallelepiped associated with the object will follow the object when its position changes.
•Designing a special point. To do this, click the Draw point button 
located to the right of the Snap Point field. Will start Subprocess of plotting a point. Select the design method and configure the required parameters.
3.A phantom of the parallelepiped is displayed in the graphics area.
Set the orientation of the axes of the coordinate system of the parallelepiped in the element group Orientation. These actions are similar to the assignment of the CSYS position in the model and are described in detail in section...LCS orientation.
You can also change position of object In the graphical area with the help of a base element.
4.Set the height of the parallelepiped in the element group Height.
Height can be set in one direction or in two opposite directions. The method for setting the height is selected using the group of buttons Method. Parameters for the selected method are set in the same way as when you build extrusion elements, with one exception: when creating a parallelepiped, there is no method to specify the height to the nearest surface.
More details on setting the extrusion direction and depth...
5.Click the Create Object button to complete the construction.
6.To complete operation of the command, click the Finish .
After plotting is completed in the model, a parallelepiped will appear, and its icon in the Tree of Construction.
Advanced Options for elementary bodies
•The length, width, and height values can be changed in the graphical area of the model – using defining points.
•To set the linear parameters, you can use the commands of the geometrical calculator.
•You can assign tolerances to the values of the operation parameters expressed in linear values. To do this, run the Tolerance command located in the required parameter menu. More details on assigning tolerance...
