How to remove 3D?

[Jean2264811005gp]

Hi. Whenever I try to create a new brush tool or move lines to duplicate them with pen tool I get a 3D effect.  I don't know how to remove this. I have used 3D in the past, tried resetting it, uninstalled and installed photoshop again but its still there.  any ideas on what I may or may not be doing? thanks

Hi

Try enabling this option in preferences and restarting Photoshop to see if it helps

Reset the preferences will fix this.

1. Press Ctrl-K (PC) or cmd-K (Mac).
2. Click on "Reset Preferences on Quit" in the "General" tab and press OK to confirm.
3. Press OK to close the Preferences window.
4. Restart Photoshop.
