Cannot reenter draw mode after inserting 3D object I'm new to Blender and I may be doing something wrong.
My goal is to use two images on textured planes for reference and draw over them.


Create new scene (File -> New 2D Animation)
Draw something (everything is working)
Add new workspace (General -> Layout)
Add Mesh -> Plane
Go back to 2D Full Canvas / 2D Animation workspace


Now I cannot select the 2D drawing, cannot get out of object mode, cannot draw anything else. Grease pencil doesn't work anymore and nothing related to what is drawn is selectable/editable.

I have Blender 2.80 Beta

Thank you.

This will return the workflow of the Grease Pencil in Blender (2.83.5) from the Layout workspace.

I will start by returning to 2D Full Canvas from the newly created Layout workspace created in OP Step 3.

With no Grease Pencil objects in the world, the Draw Mode doesn't exist returning to 2D (Full) Canvas.
(continued steps)
5. Press Shift+A &gt; Grease Pencil &gt; Blank


Drag out another Viewport and switch it to Outliner.


Select the GPencil layer in Outliner then, drag in another Editor and switch to Properties.
