Twists objects about a point. Choose an object. Specify a base point
for rotation of the object. Enter an angle of rotation in AutoCAD
command line (this angle concerns to the current object position). You
can set an angle, moving of the cursor, at which one copy of the object
will be dragged after the cursor. If the button ORTHO in the AutoCAD
status bar is turned on, then the object can be rotated only on 90
degrees in all directions.

body (solid) from two or more areas
or solids. Irrespective of the objects number , which you unite, the

consistently those objects, which you want to unite and press the right

Choose areas or dense solids, from which you want to cut out.Then
choose objects, which are crossed with them.Sequence of the operations:
- Specify with the left mouse button the
object (1), which has to be cut out and then press the right
from the keyboard.
- Specify with the left button object (2), which is
crossed with object (1) and click the right button or key Enter.
The result is object (1) with volume of the crossed area with object
(2) . If you use the opposite sequence of selection, you will cut out
object (2). The operation works with 3D solids only .

Then press the right button to unite them. You can specify closed

can not use objects, which are not in one plain, but are only crossed

negative value, you will get similar effect of thickness, but on
the opposite direction on Z.
Specify angle of taper for extrusion 0: - The program
asks about an angle of narrowing at the extension of the body. If you
press Enter,it acceptes the value by default (0 degrees). You get a
stretched (dragged out) figure, which walls are perpendicular to the
plain, in which is located the original object . You can set an angle
of narrowing between 0 and 90 degrees, at which the walls are inclined
inwards. If the angle is between 0 and (-90) degrees, the walls are

of objects sizes (scaling) -
Choose one or some objects from the project (use the left button of the
mouse). The right button or Enter
confirm your choice. Specify in the drawing an index point to begin
scaling. Then enter the scale factor. By default the factor value is 1.
If you enter value= 2, then the chosen objects will increase their
sizes 2 times. The values less than 1 decrease the overall dimensions
of objects proportionally. The operation is used for 2D or 3D

- The option TRIM cuts lines for creating of an elegant rounding ,
if you change the parameter to NoTRim, after the end of operation the
lines will be kept. The option Radius sets radius for the future
chamferings. Activation of this option interrupts execution of the
command. These two options keep the last entered parameters and applies
them by default until you don't make changes.
Select first object or [Polyline/Radius/Trim]: - Choose

fillet radius: 0.05 - Offers the last entered radius
for a chamferring of angles by default . Radius is equal to the half of
distance between two lines (angle) calculated on a direct line. For
example, if the element will be a worktop and you need to chamfer its
one side only , it is necessary to enter as value of radius for
chamferring half from the thickness of the worktop.
The worktop has
thickness 4 cm.. You must enter 0.02 (meters) for the maximal rounding
or 0.01 (m ) for smoother rounding. If value by default in the concrete
case is a suitable, confirm it with Enter.
