Thus, spline can be created by defining fit points or Control Vertices CV points. The control vertices define a control frame, which is used to control the shape of the spline, while fit points coincided with the spline. Let's understand by two examples. Example 1: Using Fit points The steps to create spline using fit points are listed below: 1.
Select the Spline icon under the Draw interface from the ribbon panel , as shown below: Or Type SPL on the command line or command prompt and press Enter. Click on the ' Method' option on the command line, as shown below: 3.
Click on the ' Fit' option, as shown below: 4. Specify the fit points by clicking with the help of the mouse. It is shown below: Continue specifying points and press Enter or Esc to exit. Click on the 'Method' option on the command line, as shown below: 3.
Click on the 'CV' option, as shown below: 4. Specify the vertices by clicking with the help of the mouse. The created spline is shown below: Note: We can also create splines with a closed-loop. The shape depends on the points defined by us. We can define as many points according to our requirements.
Edit Control Vertices Let's consider the above spline. The steps are listed below: 1. Click on the spline. The vertices on the spline will look like the below image: 2. Press the Ctrl button to switch between different operations. Spline with degree We can create a spline with any degree.
The steps to create such spline are listed below: 1. Click on the ' Degree' option on the command line, as shown below: 3.
Specify the degree of a spline. Press Enter. Solution: AutoCAD or operating system updates needed: Problems may occur if essential product or operating system updates are not applied. Operating system updates. All current updates are installed for the operating system. The computer is restarted. Issues not related to a specific drawing: Graphics issues : Update video driver and change software settings see Poor graphics performance with AutoCAD for Windows.
Use a different cable format type to connect to your screen. Use a different screen. If more than one graphics card is available in the machine, make sure that AutoCAD is using the best one.
Test disabling or uninstalling antivirus software. Try restarting the computer in diagnostic mode to disable background processes and allow AutoCAD to run in a clean environment see Use Windows diagnostic mode to troubleshoot Autodesk software issues.
Uninstall and reinstall the. NET Framework. If a newer AutoCAD release is available, install it and see whether the crashing continues in that version. Splines are defined either with fit points, or with control vertices. By default, fit points coincide with the spline, while control vertices define a control frame. Control frames provide a convenient method to shape the spline.
Each method has its advantages. However, for splines created with control vertices in AutoCAD LT, you can display the control frame only by selecting the spline. The prompts differ, depending on whether you choose Fit or CV control vertices as the creation method Method option.
Specifies the first point of the spline, either the first fit point or the first control vertex, depending on the current method. Creates additional spline segments until you press Enter. Closes the spline by defining the last point to be coincident with the first.
By default, closed splines are periodic, maintaining curvature continuity C2 along the entire loop. Controls whether the spline is created with fit points or with control vertices.
