Read and Write Nudge Key Option via Python

Rhino Developer

Hi all,

is there a possibility to access and change the Nudge Key Options via Python? There are methods in the Rhino SDK for C# and VisualBasic. I like to try a toolbox/script for immediate change during modelling.

Thank you in advance,
fishermans.

Yes.

import Rhino
#get current setting
nudge_step=Rhino.ApplicationSettings.ModelAidSettings.NudgeKeyStep

#set new value
Rhino.ApplicationSettings.ModelAidSettings.NudgeKeyStep=value

There are also

ModelAidSettings.CtrlNudgeKeyStep
ModelAidSettings.ShiftNudgeKeyStep

for the other two settings.

Basically, anything that you find in RhinoCommon can be done in Python.

Mitch,
great! You were much to fast for me.
Thank you,
Norbert.

So here I am now. Next would be, to make it - like object snap - persistent and usable same time with other commands. Is there any advice for that? I guess this is going to be much harder.
Thank you in advance,
Norbert.

arr_nudge_step = rs.PropertyListBox(arr_value_text,arr_nudge_step,"Nudge Key Values"," ")


nudge_step=float(arr_nudge_step [0])
ctrl_nudge_step=float(arr_nudge_step[1])
shift_nudge_step=float(arr_nudge_step[2])

#set new value
Rhino.ApplicationSettings.ModelAidSettings.NudgeKeyStep=nudge_step
Rhino.ApplicationSettings.ModelAidSettings.CtrlNudgeKeyStep=ctrl_nudge_step
Rhino.ApplicationSettings.ModelAidSettings.ShiftNudgeKeyStep=shift_nudge_step

print "Arrow Nudge: ",nudge_step,"  Ctrl+Arrow: ", ctrl_nudge_step,"  Shift+Arrow: ", shift_nudge_step
