command is used to rotate the selected objects according to the desired value, expressed in degrees.
By clicking on the respective command on the modify toolbar, the program prompts you to select the object or objects to rotate, once selected hit Enter or the right mouse button to confirm them.
At this point AutoCAD, similar to the move command, ask us to specify the base point, which in this case represents the axis of rotation, than is the axis respect to which the previously selected objects will be rotate.
Again, you can choose a fixed point in an object by use of “snap” (a corner, the end of a line, the center of a curve, etc.) or a random point in the drawing area.
Once you click and set the axis of rotation, the command line shows: “Specify rotation angle”, it must then enter the value of what we want the object to be rotate, for example 45 degrees.
Type 45 with the keyboard, then hit Enter, the objects are rotate and the command ends automatically.
The direction of rotation, by including positive values will be of type “Counter clockwise” in AutoCAD is set as the default so if you want to rotate “Clockwise” will be sufficient to enter negative numbers: -45.
You can enter rotation angles from 0 ° to 360 ° both positive and negative (of course do not rotate an object 360 degrees because it amounts to not rotate), using as many decimal points you want e.g. 45.99 ° or 15.2 or 30.671.
This at least in theory, then in practice you usually use whole numbers or with one decimal value, also depends on what you draw.
(In AutoCAD the comma, separating the decimal numbers is done by inserting a dot).
If you add numbers with decimal values must be used the dot and not commas. Ex 10.25 is ok but 10,25 is not correct!
Click on the "rotate" command .
Select the objects to rotate.
Press Enter or right mouse button to confirm the selection.
Establish the pivot point on the design by clicking with the mouse.
Type on the keyboard the number of degrees you want, positive or negative.
Press Enter or right mouse button. The rotation is performed and the command is finished.
