How Do I Convert 3D to 2D in AutoCAD?

by

Converting 3D drawings to 2D in AutoCAD can be a useful skill to have, especially when you need to create 2D representations of your 3D models for documentation or presentation purposes. In this tutorial, we will explore the various methods you can use to convert your 3D drawings to 2D in AutoCAD.

Method 1: Using the FLATSHOT Command

The FLATSHOT command in AutoCAD allows you to create a flattened 2D representation of a selected portion of your 3D model. This can be particularly handy when you want to create detailed flat views of specific areas of your design.

To use the FLATSHOT command, follow these steps:

  1. Select the objects or area that you want to convert to 2D.
  2. Type FLATSHOT in the command line and press Enter.
  3. In the Flatshot dialog box that appears, specify the desired options:
    • Projection type: Select either Orthographic or Perspective. Orthographic projection is commonly used for technical drawings.
    • Resolution: Set the resolution for the resulting image. Higher resolutions will result in more detailed images but may increase file size.
    • Create hidden lines: Select this option if you want hidden lines to be visible in your 2D representation.
    • Create solids: Select this option if you want solids rather than surface objects in your flattened view.
  4. Select a location on your drawing where you want to place the resulting flattened view and click OK.

This will create a new viewport containing the flattened version of your selected objects or area.

Method 2: Using the SOLVIEW and SOLDRAW Commands

The SOLVIEW and SOLDRAW commands in AutoCAD provide another method for converting 3D drawings to 2D. This method allows you to create multiple flattened views of your 3D model in a single operation.

To use the SOLVIEW and SOLDRAW commands, follow these steps:

  1. Type SOLVIEW in the command line and press Enter.
  2. In the Solview dialog box that appears, specify the desired options:
    • Create a new viewport: Select this option if you want to create a new viewport for each view.
    • Reuse an existing viewport: Select this option if you want to use an existing viewport for each view.
  3. Click OK to create the views.
  4. Type SOLDRAW in the command line and press Enter.
  5. In the Soldraw dialog box that appears, specify the desired options:
    • Select views: Select the views that you want to convert to 2D.
    • Create hidden lines: Select this option if you want hidden lines to be visible in your 2D representations.
  6. Select a location on your drawing where you want to place each resulting flattened view and click OK.

This will create multiple flattened views of your 3D model based on the selected views, which you can arrange as needed.

Method 3: Using Layouts

Using layouts is another effective way to convert 3D drawings to 2D in AutoCAD. Layouts allow you to create multiple views of your 3D model on separate sheets.

To use layouts, follow these steps:

  1. Type LAYOUT in the command line and press Enter.
  2. In the Page Setup Manager dialog box that appears, click on New Layout.
  3. In the Create Layout dialog box, specify the desired options:
    • Name: Enter a name for your layout.
    • Size: Select the desired paper size for your layout.
    • Orientation: Select either portrait or landscape orientation for your layout.
  4. Click OK to create the layout.
  5. Type PLOT in the command line and press Enter.
  6. In the Plot dialog box that appears, specify the desired options:
    • Plot style table: Select a plot style table if needed.
    • Paper size: Select the same paper size as your layout.
    • Plot area: Choose whether you want to plot the entire drawing or a specific area.
  7. Select a location where you want to save or print your 2D representation and click OK.

This will create a layout with multiple views of your 3D model arranged on separate sheets, suitable for printing or exporting.

In Conclusion

In this tutorial, we explored three different methods you can use to convert 3D drawings to 2D in AutoCAD. The FLATSHOT command allows you to create flattened views of selected objects or areas.

The SOLVIEW and SOLDRAW commands enable you to generate multiple flattened views of your 3D model in a single operation. Finally, using layouts allows you to create multiple views of your 3D model on separate sheets.

By mastering these techniques, you will be able to efficiently convert your 3D drawings to 2D in AutoCAD, making it easier to present or document your designs.
