Therefore, some people find it easier to work with polylines, as these are simpler vector entities that are supported by all CAD programs.
#GPSMAPEDIT POLYLINE TOO MANY POINTS SOFTWARE#
Of course, these features depend on the CAD software you’re working with. Image source: įinally, there are some vector editing actions that you just can’t do to a spline (e.g. In this case, the polyline is more compact than the spline. The letter ‘C’ on the top is a spline, whereas the bottom image is a polyline. The resulting drawing matches very closely too! In the image below, the curvefitted polyline is 38% more compact than the original spline! The original spline had 70 control points, which was later converted to just 43 arcs and lines. While CNC incompatibility is the most popular reason for converting splines to polylines, there are some users who do so to get a more optimized design. Meanwhile, a spline is a more general term a spline can comprise of multiple Bezier curves linked together. In layman’s terms, a Bezier curve is defined by only four points (two end points and two control points). A Bezier curve is a special type of spline, which is defined by only one polynomial function. In the world of computer graphics today, splines are easily edited by moving control points you can add, remove or move control points to alter the size and shape of the spline.Īnother term that you might come across often in CAD is Bezier curve. Back then, a flexible metal or wooden strip (called a spline) was used to construct mathematical graphs. The term has its roots from the good old days of mechanical drafting. SplineĪ spline is a smooth curve that passes through two or more specific points. In Scan2CAD, you can create a polyline from consecutive lines and arcs by selecting Vector Edit Menu > Modify > Make Polylines. Polylines are entities that are made up of lots of shorter lines and arcs that have been joined into one.
