Layout detail - how to snap to clipped geometry?

Scripting
1

Hello,

I know that clipped geometry (curves created by clipping plane) can be snapped in ModelSpace.

But I have a viewport detail placed on a layout (PaperSpace), and I cannot snap to these curves. I have one clipping plane activated just for this detail. The snap only works for model geometry, not the clipped geometry (curves) created by this clipping plane. If I activate this clipping plane in ModelSpace, the snap works well.

Is it possible to get it working in PaperSpace too? Is there any setting that I´m missing?

Thank you so much,

Pavel

Hi Pavel -

That seems to work fine in a quick test here:

Please post a .3dm file that is giving you issues and copy-paste the output of the Rhino SystemInfo command in a reply here.

Hi Wim,

thank you for your valuable input, I´ve managed to get it working, the issue was improper geometry of the clipping plane when I set parallel view perpendicular to clipping plane, but clipping plane was facing towards the viewer.

I don´t know the magic behind clipping graphics, but from my observations these curves are not real ModelObjects. How do they keep reference to ModelObject they are created from?

My issue - I´m able to get their snap point precisely, but as these are non-model objects, their Guids are zeros. I´d need the clipped object with real Guid, which is possible if the clipping plane has depth defined and I use snapping to the visible edge of actual model object being clipped.

Thank you very much for advice.

Best regards,

Pavel

Hi Pavel -

This sounds like a programming question - I’ve changed the category to Scripting.
If you provide more information on what you are trying to achieve, perhaps a developer has some tips.
