Where Is the Flatten Command in AutoCAD?

In AutoCAD, the Flatten command is a powerful tool that allows you to convert 3D objects into 2D objects. It is particularly useful when you want to create drawings that are purely 2D or when you need to simplify complex geometry.

Why use the Flatten command?

The Flatten command in AutoCAD provides several benefits:

  • Simplifies complex geometry: When working with intricate 3D models, converting them to 2D using the Flatten command can make your drawings cleaner and easier to understand.
  • Cleans up unwanted data: By flattening your drawings, you remove any unnecessary information or hidden objects that might clutter your design.
  • Improves performance: Working with large files can sometimes slow down your system. By converting 3D elements into simpler 2D entities, you can enhance the performance of AutoCAD.

How to access the Flatten command?

In order to access the Flatten command in AutoCAD, follow these steps:

  1. Select the object(s) you want to flatten. You can use various selection methods such as clicking on individual objects, using a window or crossing selection, or using filters.
  2. After selecting the desired object(s), type “FLATTEN” in the Command line and press Enter.
  3. A dialog box will appear with options for flattening. You can choose whether you want to convert only visible lines, visible lines and curves, or visible lines and text. Select your preferred option and click OK.
  4. Your selected objects will now be flattened and converted into simpler 2D entities.

Additional Tips:

Here are a few additional tips to keep in mind when using the Flatten command:

Avoid flattening complex 3D objects:

While the Flatten command is useful for simplifying geometry, it is important to note that complex 3D objects may lose their intended meaning or become distorted when flattened. Use the command judiciously and only when necessary.

Check for hidden objects:

Before flattening your drawing, make sure to check for any hidden or obscured objects that could affect your design. Use the Hide and Isolate commands to reveal any concealed elements.

Undo and Redo:

If you are not satisfied with the results of the Flatten command, you can always use the Undo (Ctrl + Z) and Redo (Ctrl + Y) commands to revert or reapply the flattening process.

By utilizing the Flatten command in AutoCAD, you can simplify complex geometry, clean up unwanted data, and improve overall performance. Just remember to exercise caution when applying this command to ensure optimal results in your drawings.
