Move face:forget the last used digit number

Is it possible sir? Like offset curve,offset surface etc

(A) Do you mean forget or remember ?
sorry for me it s not clear what you re after.

or
(B) Do you mean you want to move by 12.3456
and then Rhino should forget the last Digit “6” and use 12.345 ?

I want moveface to remember the digit.sorry sir for my poor english.

whats your native language ?
if it is german - feel free to ask your question in german.
or use google translate ?

ok - I am not a native english speaker.
But as far is I am aware - by “digit” a single numeric character is meant. by number the full value.
The number 12.34 has 4 digits.
hope this makes sense.

to answer you question:
It s a pity that _moveFace does not remember the distance / (number) that you enter.
But you can overcome this by using a macro

open
_macroeditor
then use a macro similar to

_selnone _moveFace _pause _direction _normal 0,0,0 20.0

where the distance is defined by the origin and 20.0 units.
still needs a final click in the correct direction.

modify the macro to fit to your needs.
find some infos here:

not that you can repeat the macro with _space / _enter /right mouse button (depend on your habits / settings)
