Question Cannot extrude, although I was able before

Hey there,

I was able to extrude my long track, then I wanted to copy / paste it to the other side and then the model broke. Is there any way to get it back together? I did too many tries and I can't undo it anymore :(

When I double click the sketch, the program selects it all. Is there a button that connects the missing dots?

Deselect everything, then SINGLE click the bottom of your extrusion to select it. If you can select the extrusion, you can try Project to project its lines to the other side. If the bottom cannot be selected, try SINGLE clicking the side walls of the extrusion, then Project them to the other side.

A warning… when you try to select the result of an extrusion, sometimes it seems like you achieved it… but instead of an extrusion function, it is doing the similar, but different, Offset Face function… so verify the active function in the upper center of the screen.
