Spline, AutoCAD 2021
This video provides a tutorial on the Spline command in AutoCAD 2021, which is used to create smooth, flowing curves, often for organic or architectural shapes like landscaping and pools. The video compares the two main spline types—Fit Spline and Control Vertices Spline—and their relationship to the curves created using the Polyline Edit (PEDIT) command. The instructor also demonstrates key editing tools, like converting a spline to a polyline and adjusting the tangency direction at the ends of the curve.
