9 Basic Editing Commands
Undo
Toolbar:
Menu:
Edit - Undo
Hotkey:
oo, Ctrl-Z
Command:
undo, u
Description:
The Undo command takes back the last drawing or modification command
that was executed. QCad can take back more than one command. E.g. if you've
just created a line and a circle which you want to take back, launch the undo
command twice.
Undo cannot undo all actions. Some actions like file actions and layer
actions can't be undone.
Redo
Toolbar:
Menu:
Edit - Redo
Hotkey:
uu, Ctrl-Shift-Z
Command:
redo
Description:
The redo command is the counterpart of the undo command. It makes
changes undone before reappear.
Copy
Toolbar:
Menu:
Edit - Copy
Hotkey:
Ctrl-C
Command:
?
Description:
You might know the copy / paste mechanism from other applications. QCad
offers a similar set of tools to copy entities from one drawing to another.
Objects that are copied are stored on the QCad internal clipboard. This
clipboard can only be accessed from QCad itself. You cannot paste graphical
objects copied in other applications into QCad nor can you paste
QCad entities into other applications.
Procedure:
- After starting the copy tool, the CAD toolbar shows the selection
tools. Use them to select the entities you want to copy to the
clipboard.
- Click the right arrow button in the CAD toolbar to continue.
- Set the reference point with the mouse or enter a co-ordinate in the
command line. The reference point will be used to position the entities
when pasting them into a drawing again.
Cut
Toolbar:
Menu:
Edit - Cut
Hotkey:
Ctrl-X
Command:
?
Description:
The cut command essentially works like the copy command described
above. The only difference is that the selected entities will be removed from
the current drawing after being copied to the clipboard.
Paste
Toolbar:
Menu:
Edit - Paste
Hotkey:
Ctrl-V
Command:
?
Description:
The paste command inserts the entities previously copied to the
clipboard. Paste is especially useful to transfer entities from one drawing to
another.
All layers needed by the clipboard contents are pasted into the layerlist.
Existing layers with the same name don't get overwritten. Sometimes this
might lead to unexpected results. If an entity gets its attributes from the
layer, it might be red in the original drawing and appear green in the
drawing where you paste it. That's the case if a layer exists in both
drawings with different attributes.
Inserts (references to blocks) that are on the clipboard will be pasted
together with the blocks they refer to. Blocks in the current drawing don't
get overwritten. This might lead to totally unexpected results in some cases.
Make sure that different blocks never have the same name in drawings for
which you use the copy / paste tools.
