    I am presently using SwitcherCAD III and am having problems with
    rotating objects. The rotate command in the edit menu is always
    grey, even if I have selected the object. The ctrl-R shortcut
    doesn't work too.

    Can anyone tell me how to rotate the object?

    (I read in the help menu about something called "object sprited"
    What does that mean? How do I use this to activate the rotate command
    in the edit menu?)

    *****
    ....Hence, when you wish to move, mirror, rotate, drag or delete objects,
    first select the move, drag or delete command.
    *********
    LTSpce is completely nonintuitive regarding how its GUI actually
    operates for tasks like this. Better GUIs allow, for example,
    SuperSpice, "move mouse over component", press the "r" key. Guess how
    you Mirror or Flip or even delete components:)

  3. Hello Stan,
    I have answered the same question a few minutes ago in the
    LTSPICE users's group at Yahoo:
    http://groups.yahoo.com/group/LTspice


    Hello ...,
    you simply forgot to go into move mode.

    Instructions follow:

    1. click on "Move", this is the "full hand" icon on the top toolbar

    2. click on the component you want to move/rotate/mirror or select
    many by clicking and dragging a box around it.

    3. Press "<ctrl> and r" for rotate or "<ctrl> e" for mirror of the
    selected item.
    It is mandatory to first press the <ctrl> key and keep it down and
    then press the r or e key!!!

    Best regards,
    Helmut

    PS: It works this way on ten thousand other PCs. If it doesn't work,
    then your <ctrl> key has a defect.


    Stan, take the small learning curve with LTSPICE and you will
    never miss it.
    Hello Kevin,
    I fully disagree!
    LTSPICE has a great GUI and is optimized for easy and and really
    fast drawing. I like it. The whole GUI is really well organized.

    The GUIs in other CAD programs with their thousands toolbar icons
    are a nightmare.

    Best regards,
    Helmut

    Hi Helmut,
    I agree entirely.
    Certainly not ideal for running on notebooks, that's for sure. But
    Kev's front end is actually pretty good, to give credit where it's
    due. I wouldn't put the SS GUI in the "nightmare" category - unlike
    its author. :)
     
  5. Well, we all have our own opinions. Every time I have a go at LTSpice
    for drawing, it comes across as so cumbersome. It just don't do what one
    expects it to do.
    I ceratinly agree that some other spices are much harder to use than
    LTSpice.

    I have played with SuperSpice on computers with LCD displays. Looks nice, but
    most LCD's can only get to 1024x768... :/

  7. I have to agree, that one wants as much resolution for SS as possible.
    My monitor is set for 1280 by 1024. However, to address the prior point,
    I don't have many icons on my toolbar buttons. Its letters for the first
    word of what it does for most. I find icons confusing. AC DC TR OP (for
    enabling different runs) seem pretty much self explanatory.

    This is a Good Thing (TM) of SS. The interface isn't full of stuff.

    That's the minimum res with which I could comfortably use SS, IIRC.
    It's what I'm set at now. SS is only *one* of the screen consumptive
    apps I run, well, ran it a couple times, anyway.
