Manually adjust the Z-value of a control point

Hi everyone,

I would love be able to adjust the Z-value of my control points, as I do in the “box edit” with a point in Rhino, by adding the value as a Z value in relation to world zero.

E.g. If I type 10 the points ends i z = 10


With controlpoints I can use the “setPt” command, but how can I create an alias by default use this setting:

!_SetPt _pause “something here xx”?


Use the dash version of the command. I have aliases for setting X, Y and Z coordinates that have macros like this:

! _-SetPt _Pause _XSet=_No _YSet=_No _ZSet=_Yes _Alignment=_World _Copy=_No

Then you can just type a number for the world absolute Z value and Enter.

Thank you so much Helve!!


In fact, where do you find these macros for each rhino command?

I couldn’t figure out how the macro/code for “_xset” and “_alingment”…etc.

I hope its okay to ask,


For things like this, type the dash version of the command at the command line and look at the options…

Ahh, great, that’s nice to know :slight_smile:

Thanks a lot!

Thanks for your advice Helvetosaur. As a beginner in Rhino, I’d be really interested to know if the following command would work, in order I could set the Z value referring the CPlane and not the absolute World coordinates:

! _-SetPt _Pause _XSet=_No _YSet=_No _ZSet=_Yes _Alignment=_CPlane _Copy=_No

Have you tried it? If you try it and don’t like the result then the Undo will undo the results.

Yep, it worked. It’s a very interesting command.
