Question about accusSnap automatically displaying graphics

[Cagliostro-code]

My current situation

| The iTwin version i am currently using is 3.7.5.

When i use accuSnap.enableSnap(true), a red graphic indicator automatically appears when approaching a key point, as shown in the image below.

When testing with the online preview on the official website, I noticed that in some cases the graphic sometimes changes color depending on specific conditions. And I even noticed in the Issues section that others were able to disable this indicator, as shown in the image below.

My question

My question is: im my local project, how can I control or customize the color of this indicator, and possibly modify the logic for showing and hiding it?

That is showing the surface normal (or up vector) for the geometry being snapped to. It is only displayed in 3d, which is why it's not shown in your second image. It's drawn using the inverse of the Hilite.Settings color returned from Viewport.hilite.

Thank you very much for your response.😊 I successfully modified the color of this graphic by adjusting viewport.hilite.

If I understand correctly, the reason it's hidden is simply because it's a 2D model, and it's iTwin's built-in logic. Additionally, at least for now, iTwin does not support freely controlling the visibility of this content. right?

[bbastings]

Correct, no point showing snap normal in 2d when it's always the same.
