Can someone please explain the thought process behind guidelines being invisible except when you’re in a selection mode? This seems counter-intuitive to the intended use of guidelines. I want to see them so I know if a layout is going astray for example. Or, if I want to know where to pick, it would be good to have the lines visible so I can plan how to draw something when I’m not in a selection mode.

Hi Dennis - just to avoid clutter. Do we need a ShowGuides command?



Hi Pascal,
Indeed, It would be so useful!

Oh, and here I thought that was birthday cake!



That would be excellent.

Hi Pascal, I have found guidelines super useful since they are visible through solids without going to ghosted view and faster to set up than greyed out guides on a locked layer. I agree with Dennis I want to be able to control visibility with a toggle but would like to make 2 additional requests.

  1. Please consider giving the user the control over the darkness of the lines with a slider. Sometimes I really need to see them clearly, sometimes I just want them way back.
  2. Why limit to straight lines? Please let me draw free hand guides or reclassify existing curves as guidelines too.

Hi Abraham - you can make a few aliases or buttons to conttrol guide color in the form

! _-Options _ModelingAids _SmartTrack _GuideColor 255,255,10 _EnterEnd

For now, you can make any curve into a workable guide by putting them on a layer and setting BringToFront on them, then locking the layer. Toggling the layer visibility will toggle the guides. Not exactly the same but with some clever macros, possibly workable.

! _Select _Pause _BringToFront _-Properties _Object _Layer MyGuides _EnterEnd

Thanks Pascal! Much appreciated. I used Artcam earlier this year for a project that involved quite detailed relief carving on an arched surface and liked the way I could use a slider to touch up the visibility of reference guides as I worked. The slider controls the contrast of underlying guide images, kind of like a BackgroundBitmap, or of the relief layer material. Hope something like this will find it’s way into Rhino soon.


We need fairly long debate about the guides. The fewer commands, the better! We already have 931 commands. Few if any Rhino users can memorize all of them. Worse yet, there are many Tweedledum and Tweedledee commands

I would replace the two commands (AddGuide and RemoveGuide) with one command named Guide. Within this command I would give the users all the options they want.


I would have a tendency to agree with Andrew here, something like Guides or Guidelines with all the options might be more coherent. The options could be macroed for buttons.

  • Add (interactive)
  • Remove (interactive)
  • RemoveAll
  • ShowAll
  • HideAll
  • ShowSelected (interactive)
  • HideSelected (interactive)
  • Visibility (toggle persistent/ondemand)



How about just on or off? Easy-peasy!
