Why can't I go back to editing?

This is really starting to bug me. When I’m in edit mode and I finish the first part of the thing I’m making, I go into object mode so I can create a mesh to work on the second part. When I go back into edit mode, I can’t edit the first part I worked on, and this is really starting ot bug me :mad::mad::mad::mad::mad::mad:

Anyone know why or can anyone help?

When you switch from EDIT to OBJECT mode, you’re creating two separate Objects. If you want them all to be the same object, then don’t switch out of EDIT mode before adding another cub/sphere etc.

Otherwise, as you’ve created two separate objects, you need to select the first one with RMB before going back to EDIT.

Or you can select both objects with either SH-RMB or (b)ox select and then join them into one object with CTR-J.
