When did that happen?

a loong looong time ago in a time where curves where shown as a point in an ortho view all was good and pretty.

then came the dark and evil times when the gods of Rhino made these little indicators disappear with no reason at all, and the outrage of the poor users was great who had to deal with sudden changes they could not live with any longer but had to anyway.

after many years of darkness a little twinkle of light, there right there in Rhino with sudden dots appearing again indicating that there actually is life in this stubborn hard skinned and horned animal after all.

so my question while i am still wiping the tears of joy from my cheeks, when exactly did this happen?

Don’t know exactly, a bit before SR10.

I now see it’s gone again in the WIP (9.0.25177.305, 2025-06-26):

Current V8:

Hi Charles -

→ RH-88174 Display: D3D: Line not visible head-on
This works as expected on Rhino 9 on macOS and when using OpenGL on Windows.
Please always mention that you are using an experimental feature when reporting an issue.

Sure.
But in this case I don’t, as advised by Steve:

Urgs.
From SystemInfo:
Standard graphics configuration using DirectX

Sorry, I was not aware of that change.

so, i know why i did not notice the reinstatement

the point is disproportionately smaller, not by much but having the curve set to 1 or even 2 makes the point actually almost invisible. to compare i put the orthogonal line next to the horizontal, the dimensions are in mm. the dot is 10 mm left of the horizontal, if you squint your eyes you might find it. it seems like a half a pixel smaller, or the antialiasing is slightly different making it appear smaller, tested in v9 with thicker curves it appears by 1 or 2 pixel smaller.

different colour that one can at least see it now

is there (can there be) a setting to change that individually?

RH-88174 is fixed in Rhino WIP
