How do you close a polygon in AutoCAD?
You can “close” a Polygon when creating it. When you’ve picked the last point, instead of moving the cursor over the starting point to close it, merely type “C” and it will close the polygon. Check the Command Line and you will see “C” for close.13 jan. 2014

What is the use of spline command?
The spline command in AutoCAD is used to create a smooth curve, which passes through a set of predefined points. It creates a non-uniform curve passing through the points. Thus, spline can be created by defining fit points or Control Vertices (CV) points.
What is the difference between spline and polyline?
Splines curves are curves that are represented by a special class of mathematics. Polylines on the other hand are line segments strung together. In VisualMill all splines are converted to polylines using the tolerance specified in the machining operations before the toolpath is created.6 sept. 2007
What is a spline in math?
In mathematics, a spline is a special function defined piecewise by polynomials. … Splines are popular curves in these subfields because of the simplicity of their construction, their ease and accuracy of evaluation, and their capacity to approximate complex shapes through curve fitting and interactive curve design.
