No Osnap on Rhino 5 for Mac

Hi -
Recently started working with Rhino .

However right now I have zero snap from any Osnap settings -

Have actually thrown all preferences / reinstalled but still no snap to even 2D curve objects ,
I went to preferences and set all to on in Modeling Aids / Snaps and after enabling all I could snap to objects but after changing one setting all vanished .

Am I missing something simple - as far as I am aware All preferences are set to installation default .

very confused and frustrated… any suggestions how I might resolve this

And if you make a video showing the problem?

I’m a Windows Rhino6 user:

  • Open a new Rhino.
  • Make a polyline.
  • On the Osnap panel enable end.
  • Make a new polyline and
  • notice that snaps to the end of the first line

Hi ,

Yes - This does in fact work in creating one object in relation to an existing object - snap definition .

Perhaps Im expecting something which is very simple and doesn’t exist . I refer to
Transforms Page - being able to drag objects to or from snap definitions .

Im coming from using CAD modelling where being able to pull objects to snap points is a simple action and by the Rhino document above this should apparently be so _ however _ I have no snap definition available except with “Move” command .

Sorry - this is very / extremely basic … but Im just alarmed I evidently cannot drag and accurately move in such simple terms,–
IE. There must be something wrong with where I am .and would like to find a resolution somehow


You need to figure out the details of “Control Point Editing”.

Turn on the control points for the objects you want to change, and select a control point to drag. If you have a persistent osnap set, you can drag that point to a destination point where you want it to go. Make sure the osnap tooltip shows the specific point (End, Mid, Perpendicular, Center, Quadrant, etc.) you’re looking for before you click.
Rhino will never guess at what it thinks you are close to. Rhino doesn’t think. You have to. The Tooltips are Rhino telling you what it found.

This is all covered in the Getting Started tutorials.

Thankyou … if so then … I have to turn points “on” / Points “Off” before I can pick up by a specific snap ?

I ve got the control point principle -

That this had to be turned on / off prior to moving an object I wasn’t aware of . missed that bit …
sorry, initially this seems to be quite a few steps to get to achieving a simple snap point -

so far from what I have attempted it even this seems to make little difference but I will keep working at it

In Rhino V6, when you select curves and dimensions, their control points are automatically turned on. Eliminating the extra step is specifically why the change was made.

In Windows Rhino, F10 turns points on and F11 turns them off quickly and easily. The keyboard is different in Mac and for me at lease, not nearly as easy to use. I’m sure others will have methods for Mac keyboards that work well for them.

So, with End osnap active, if you make a box for example, and you bring the mouse cursor near one corner of the box and hold down the left mouse button, the ‘End’ snap doesn’t light up?

Does making the Grid active provide what you are seeking? “Grid snap constrains the marker to an imaginary grid that extends infinitely. You can set the snap spacing to any value. Click the Grid Snap pane on the status bar to turn grid snap on and off.”

With the grid active you can use any of the active Osnaps to grab an object and move near the desired location. It will then snap to the nearest grid point. Similarly if you are creating geometry your cursor will snap to the nearest grid point when asked for a point location, etc.

Take some time to review the User’s Guide, particularly the section on Accurate Modeling.

HI Helvetosaur ,

actually - initially I would have said NO -

but then again … actually YES

I have to be right on top of the snap point - zoomed in to very very high degree .

so yes in fact it is there , just on a very short response for the scale .

Any advice possible on what determines the responsive distance to snap location ?


Rhinoceros pull-down menu > Preferences > Modeling aids:
In the Object snaps section, there is a snap radius Mine is 15 pixels which seems pretty comfortable.
You might need to adjust your radius and restart Rhino until it’s comfortable for you at your screen resolution and size.

I must look at this - preferences are set at 20 pixels … Im working on a perfectly normal 27" apple monitor _ seems odd I should be dealing with such extreme dimensions/ distances _ but I will have to try out if these settings are what I am dealing with here .
