Join Jim LaPier for an in-depth discussion in this video Splines, part of AutoCAD for Mac 2015 Essential Training.
- A spline is a complex object in AutoCAD,…similar to a polyline,…but infinitely more involved.…When a polyline is exploded,…it is broken down into arks and lines.…Which would seem to make it…a mathematically-based object.…However, despite its fluid shape,…a spline is technically more mathematical in nature.…Owing its tangential curves and arks…to polynomial functions.…Like ellipses, they can be a bear to work with…if ever exploded or broken apart,…and they don't particularly play well…with 3D modeling functions.…
However, like ellipses, for the most part…we can let AutoCAD do the math for us…and create some very interesting shapes.…Like the polyline tool…we'll create a fluid, closed shape.…Though splines can be open-ended like a polyline…by typing in the word spline.…From here, we can pick our points,…but notice the points we're picking are not vertices.…Merely points through which the spline will travel.…Also notice as I move my cursor to select my next point,…how the previous arks and lines…seem to move to accommodate this new point.…
