What option is used to create a studio spline through specific locations?

The option to create a studio spline through specific locations is titled "Through Points." This method allows users to define a spline by selecting precise location points in the modeling environment. Each selected point acts as a control point for the spline, ensuring that it passes through these specified locations, which is essential for accuracy when designing complex shapes or components.

Using "Through Points" provides a straightforward and intuitive approach to spline creation, giving users a direct visual representation of how the spline will interact with the designated points. This is particularly valuable in design scenarios where maintaining precise alignment with defined geometry is crucial.

Other options like "By Poles," "By Nodes," and "Exact Spline" serve different purposes in spline creation and manipulation. However, they do not specifically focus on ensuring that the spline passes through chosen locations as "Through Points" does, which makes it the ideal choice in this context.
