Pick depth on existing strokes ?

[materialjan]

Hello thank you for putting this online.
I tested the hda and found I couldn't anchor new strokes on existing ones if the screen space for drawing was rotated.
Although the depth picker work for the geo it doesn't pick existing already drawn strokes.

I was hoping to find some resolve for a similar problem i'm facing

Where I simply want to get the intersect point in screenspace to world space and set the projection center before a stroke is made. If you have a solution for that it would be helpful. Thank you.
