As I’m figuring out how to do things I often find that I sketched something and extruded, but I want to change the sketch, and redo the Extrude. It seems that the two are separate, so if I move my splines, the bodies stay unchanged. Can I delete a body somehow without loosing the sketch it was made from?

**SORRY! The Clips are not playing I will redo them and get right back**  
Having remade the Clips they still do not function ON THIS PAGE although run fine elsewhere.  
**Rebooting my Mac resolved the problem**.

@thepian  
Sketches, in the form of **Closed Shapes** , can create a Body.  
When Bodies are created they are immediately separate from their Sketches, just Delete the Body the Sketch is untouched:

If your Sketch is complex and you need to make alterations use Design Thumbnails to create a Duplicate, and then work with the Copy version:

**NB**. Remember to tidy up after making the alteration Rename or Delete as appropriate before you get ‘buried’ in Designs.  
I am now going to Delete all the ‘designs’ created to hide my work 🕶.
