A dangerous characteristic of Cadence layout editor

If I click and drag the mouse when an instance is selected, the
instance will be moved even without entering the "move" command. It is
quite dangerous, because sometimes I even didn't realize that some
instances are selected. How do you guys deal with it besides to be
more careful? Thanks!

That is the implicit move operation. You select an object, click within
the object and drag the mouse. The object moves. It works with any kind
of object, not just instances. I've never found a way to disable it.

 

Redefine the default left mouse button draw through bindkey in layout by doing
this:

(foreach application '("Layout" "Schematics "Symbol")
(hiSetBindKey application "<DrawThru1>" "geSingleSelectBox()"))
)

and this will stop the dragging behaviour in layout, schematics and symbol
editor.

I've used this approach for the last 10 years or so since I never liked the drag
behaviour myself.

Dear Andrew,

It works very well. Thank you very much!
