Hi -

Is that the case no matter which display mode you use in the viewports?
Do you see a preview while you are creating a curve but that then disappears when you are done drawing?

Its the same in all viewports, and yes it just disappears

Pls check out the Curves option in the Display Panel,

Dumb question, but it seems your x and y points are relatively large. What are your units? It shouldn’t be an issue, especially if you’re not tens of thousands of units away from the origin. Try drawing the same thing on a Construction Plane that passes through the world origin point.

EG, invoke “cplane” select “world” “top” , find 0,0,0 and go there to draw your polyline.

Believe it or not, but I see this come up a surprising amount.

Good luck!
