I’m not sure if this is a bug or it was intended to be seen. When I drag or move a part it shows pipes inside the part.

This has been around for a pretty long time now. It’s just showing that the part that you’re resizing is touching other parts.
I never had this happen before : o
Why have these pipes though? It’s kinda odd to me, I know that they had a red outline box pop up when collisions happen.
That’s not a bug, that’s a feature that allows you to weld adjacent parts together.
To toggle this feature on and off, click the Join button under the Model or Home tab, and select ‘None’.
