How Plotter in AutoCAD Works?

Understanding the Functionality of Plotters in AutoCAD

Overview of Plotters

Plotters are essential tools used in conjunction with CAD software like AutoCAD for producing high-quality, precise graphical outputs on paper. Unlike traditional printers, plotters are specifically designed to create vector graphics, making them ideal for detailed line drawings, architectural plans, and engineering schematics.

The Role of Plotter Configuration Files

To effectively use a plotter with AutoCAD, you first need to configure it through a Plotter Configuration File (PC3). This file saves all necessary settings tailored for different plotting machines, ensuring that you can easily reuse configurations across multiple projects. Users can access the settings either by entering the command PLOTTERMANAGER in the AutoCAD command line or by navigating through the application menu to manage plotters.

Utilizing the Plot Command

The plot command in AutoCAD facilitates the process of sending drawings from the Model tab or layout views directly to the plotter. By selecting the plot option, users can specify various settings, such as plot area, paper size, and scaling. This command allows you to control the output, ensuring that only the desired elements of your design are printed.

  1. Select the Plot Area: Choose to plot the entire drawing, specific layouts, or the current view in the viewport.
  2. Configure Settings: Adjust settings like paper size and orientation according to your design requirements.
  3. Preview: Always preview the plot to confirm that everything appears correctly before finalizing the print.

Understanding Plotter File Formats

Among the commonly used formats for plotters is the HPGL (Hewlett-Packard Graphics Language) Plotter File (PLT). This vector-based format is tailored for communicating with plotters and is characterized by its scaling, where 1,016 plotter units equate to one inch. This allows for accurate reproductions and is widely compatible with various design applications, including AutoCAD.

Types of Plotters

Several types of plotters are prevalent in the industry, each serving different applications:

  1. Drum Plotters: These utilize a cylindrical drum to move the paper during drawing, making them suitable for large-scale drawings.
  2. Flatbed Plotters: Ideal for precise graphics, flatbed plotters hold the paper stationary while the pen moves across it.
  3. Inkjet Plotters: These use ink cartridges to produce high-resolution images and are popular for their versatility and color range.

Cost Considerations

Investing in a plotter can vary greatly depending on the model and its capabilities. Prices generally range from $1,500 to $3,000, with advanced models capable of large formats and specialized outputs, such as the Vinyl Q Series, costing between $2,000 and $4,000.

Setting Default Plotter in AutoCAD

Setting a default plotter can streamline the plotting process in AutoCAD. To configure the default plotter:

  1. Open AutoCAD and input the command OPTIONS in the command line.
  2. Navigate to the Plot and Publish tab.
  3. Under Default Plot Settings for New Drawings, select ‘Use as Default Output Device’.
  4. Choose your preferred plotter from the list and confirm by clicking OK.

Practical Tips for Plotting

  • Regular Maintenance: Keep the plotter well-maintained to avoid issues like ink smudging or mechanical failures.
  • Choose the Right Media: Depending on the output requirements, select the appropriate paper or plotting media to achieve the desired quality.
  • Monitor Ink Levels: Regularly check ink levels for inkjet plotters to ensure continuous, uninterrupted printing.

FAQ

  1. What’s the difference between plotting and printing in AutoCAD?
    Plotting refers specifically to producing vector graphics usually associated with architectural or engineering outputs, while printing often handles text and lower-resolution images.

  2. Are plotters still relevant with modern technology?
    Yes, although wide-format printers have become more common, plotters still hold niche importance in industries that require precise and scalable vector graphics.

  3. Can plotters be integrated with other software besides AutoCAD?
    Certainly, many plotters are compatible with various design and illustration software, enabling versatility in professional applications.
