# Can i draw precise sphere in perspective using illustrator?

I really need to draw ellipses and spheres in perspective so I wonder if Illustrator is set to do this kind of tasks, I tried and came up with this result:

But as you can see It's not precise and it takes a lot of time to draw ellipses in perspective, So I wonder if anyone came across a better way or maybe a better appllication for perspectiv drawing??

• That image does not look like its in perspective the edges are parallel, its some sort of a parallel projection. May 3, 2016 at 6:29

Yes its possible. But remember that the perspective projection of a sphere is actually an ellipse (see this explanation.

Image 1: A isometric spheres (left) projection is a circle. In a perspective that projection is actually an ellipsoid.

First find the approximate center draw a approximate sphere (tip holding space lets you move center) then rotate the sphere to cardinal direction and scale it up a bit. Takes about 2 minutes to be almost accurate once you've practiced. This is by far more accurate than trying to eyeball the settings for 3D Rotate or 3D revolve.

### Finding the projected ellipses major axis

The major axis of the ellipse is oriented towards the center of your perspective or simply the one point perspective vanishing point.

... How do i draw this? ... sorry must go again

• I understand the projection, But i don't understand how did you do it?? in my first picture i draw rectangle for every ellipse and used pen tool.. but i don't understand how you did it? May 3, 2016 at 7:22
• @Corabict yes i got interrupted May 3, 2016 at 9:17
• Thanks a lot man, but my problem isn't in the perspective construction but how to implement it precisely Inside illustrator, So I'm waiting for you May 3, 2016 at 11:47
• Yeah, until @joojaa actually answers the OP's question, gonna have to downvote this one... Apr 19, 2020 at 21:38

Try using Illustrator's 3D Rotate feature.

3. Click `Effect > 3D > Rotate`
4. Adjust the various axis and click `OK`
The result will be your original shape with the live effect applied to it, which you can go back into and adjust. When you're happy, click `Object > Expand Appearance` to convert your 3D shape to a path.
