Drawing on an invisible plane 90 degrees to the camera

[Anonymous]

I want to draw a spline 90 degrees to the camera (as if there were a plane to draw on that is facing the camera)

How can I do this?

Go into your helper objects menu and create a grid object, link it to your camera. Then activate the grid and draw on it.

Its easier to set it up perpendicular to the camera if you are starting with a clean scene, but you could use the Align tool to align the grid to the camera.

Anything you draw on the grid will have to be linked to the grid if you want the grid and the object to follow the camera.

There are probably other ways to do this but this should work.

In addition to the suggestion James did above.

If you need the 90 degree precisely without alignments, do it like this:
Crate a plane in the front view-port, convert into perspective, then go View, Create camera from view.
All this done go Helpers, check Auto Grid, drag in the view-port to create a Grid object aligned to the Plane, make it active and now when you create a spline it will be where you want it. (Don’t forget to make the Plane invisible to the camera.)

A bit long and complicated but very precise. 🙂
