Why are visible lines important in technical drawings?
They help identify the outline and visible features of an object in a specific view.
They are used to show the internal structure of an object.
They indicate the material used in the object.

What are long break lines typically used for in technical drawings?
To show that the middle section of an object has been removed so it can be drawn on a smaller piece of paper.
To indicate the outer boundary of an object.
To represent hidden features inside an object.
