We're making a change to how objects are deleted and v hidden when creating your 3D presentations ("Jigs").
In an upcoming release, we will remove the ability to "Delete" a sub-object, mesh, or sub-assembly from a step in your Jig, unless you are removing the object from the whole presentation.
All other times, we will have a more distinct "hide object" feature, so you can hide an object in both the editing environment, and the viewer when you publish. Any time you do this by mistake, you can undo or un-hide the object in question.
We hope this simplification helps in these tricky situations where previously there was a problem being unable to "restore" a deleted item on a step.
---- Original post ----
When I delete an object on one step, that still exists on others steps, I should be able to restore it.
Object list makes this easy to see deleted objects on a step-by-step basis. We will add a restore feature to this.
Restoring a deleted object will restore it to its default properties.
