Understanding Plotter Files in AutoCAD
Plotter files play a crucial role in the printing process within AutoCAD, providing a method for outputting precise graphical representations. This article explores how these files work within AutoCAD, focusing on the formats used and their applications.
What is a Plotter File?
A plotter file is typically created in a vector-based format, with the HPGL (Hewlett-Packard Graphic Language) being the most recognized type. The HPGL format is specifically designed for use with plotters, allowing users to produce intricate and detailed graphics, such as blueprints and designs. When working in AutoCAD, this format translates computer commands into physical drawings on paper, utilizing a unit conversion where 1,016 plotter units equal 1 inch.
How to Create and Use Plot Files in AutoCAD
Plot files are utilized to manage how designs are outputted, enabling users to send jobs to printers or plotters effectively. Here’s a step-by-step guide to generating and utilizing plot files in AutoCAD:
-
Open Your Drawing: Begin by opening the drawing you wish to plot in AutoCAD.
-
Access the Plot Dialog: Navigate to the “Plot” option, typically found in the File menu or accessible via the command line.
-
Choose Plotter Configuration: Select the appropriate plotter from the list provided. Ensure that the configuration matches the output required for the specific project.
-
Set Plot Style: Assign a plot style (CTB or STB) that dictates how colors and line weights will be printed. This step is crucial for achieving the desired visual effects in the final print.
-
Adjust Paper Size and Orientation: Choose the correct paper size and orientation for your drawing. This ensures that the plot fits well on the selected medium.
-
Preview the Plot: Use the preview function to check how the plot will appear when printed. This step helps to identify any potential issues before committing to the print.
-
Save the Plot File: If you intend to reuse this plot setup, save the configuration as a PLT file. This can be done by selecting the appropriate option in the plot dialog.
- Output the File: Finally, send the plot file either to a physical plotter for immediate output or to a spooling service for later printing.
Configuring Plotters in AutoCAD
The setup and configuration of plotters are essential for achieving quality outputs. Here’s how to configure plotters in AutoCAD effectively:
-
Access Plotter Configuration Editor: Go to the “Output” tab, and find the "Plot" option followed by “Manage Plotters.”
-
Modify Settings: The Plotter Configuration Editor will allow you to tweak settings related to port connections, media selection, and other output options. Each configuration, such as calibration and custom paper sizes, can be tailored to meet specific needs.
- Save Changes: After making modifications, ensure that you save changes to the plotter configuration for future use.
Common Types of Plotters
When selecting a plotter for use with AutoCAD, it’s important to recognize the different types available, as they cater to various needs:
-
Drum Plotters: Known for their speed and ability to handle large formats, these plotters are ideal for printing large-scale designs.
-
Flatbed Plotters: These plotters manipulate a flat surface where the paper or medium remains stationary, making them suitable for intricate designs and materials that require stability.
- Inkjet Plotters: These are versatile and can produce high-quality images and colors, making them popular for both professional and personal uses.
Differences Between Printing and Plotting
Understanding the difference between printing and plotting is vital for effective output. Historically, printers have focused on text documents, while plotters have been designed for graphical output. Plotting often involves generating vector graphics, which retain their integrity and quality when scaled.
FAQs
1. What types of files can I save when plotting from AutoCAD?
You can save your plotting output primarily as PLT files, which are suitable for vector graphics and can be utilized with compatible plotters or printing services.
2. How can I troubleshoot plotter issues in AutoCAD?
If you experience plotting issues, check your plotter settings, ensure the correct device is selected, verify connection ports, and review scale settings. Print previews can help identify problems before physical output.
3. Can I customize plot styles for different projects in AutoCAD?
Yes, AutoCAD allows users to create and customize plot styles in either CTB or STB format, enabling specific color and line weight mappings to suit different projects and output needs.
