Using the explode tool when drawing in 3D breaks the component into different lines what I want to know is there
a way to join them again
Thanks

Yes you can explode a solid. You get 2D surfaces. Do a list on one. That'll tell you everything you want to know. You can then explode the surface to individual lines.
BUT- NONE OF THIS HELPS ANSWER YOUR ORIGINAL QUESTION.
No, there's no "Automatic Reconstruct" function for returning the lines to a solid. Sorry.
If you need to extract a shape from a solid, set it aside into its own seperate file, and explode it there, or if you've not done anything else, capture the exploded shape you needed with a copy-clip or cut, and use undo to return to the solid. The copy-clipped or cut shape is still on the clip board. Re-insert it by paste wherever you need it, including another solid you might have opened to receive the shape.
Too late now, but for future reference...
Before I explode a solid, or extrude a complicated profile, I save a copy of it to a layer that I have simply called "Backup". This layer stays turned off, and If I need something, I just turn the "Backup" layer on, and reuse whatever I need. Once you explode or erase, and you close ACAD, it is pretty much lost for good. Sometimes I am able to recove an older automatic-save, and pull the parts out that I need.
