In this post I want to introduce the SPLINE command in AutoCAD. In other posts I have already introduced other important objects and commands in AutoCAD, such as e.g. AutoCAD XLINE, AutoCAD PLINE, AutoCAD POLYGON etc.
A spline is curved line that runs through or nearby a set of fitpoints.
Below I enter the SPLINE command in AutoCAD.
AutoCAD will ask me to specify the first point of the spline, which I can choose by clicking the respective area in the drawing. AutoCAD will then ask me for the next point, and the next point, and the next point … I can complete the SPLINE command by pressing ENTER.
Below is a complete spline which I have selected. As you can see its grip handlers are highlighted.
If I click the triangular shape two options will be prompted: “Fit” or “Control Vertices”. By default, fit is selected. This mean the spline will run through the fit points, resulting in a perfectly fitting line. I can manipulate the spline by adjusting the fit points.
If I instead select “Control Vertices” the line will run near control points. I can manipulate the spline by adjusting the control points.
This completes my tutorial on the SPLINE command in AutoCAD. In other posts I have e.g. demonstrated how you can use pyautocad in Python to develop Python scripts for AutoCAD.
