How Do I Select a Base Point in AutoCAD?

AutoCAD is a powerful software used for creating 2D and 3D designs. One of the fundamental tasks in AutoCAD is selecting a base point.

The base point serves as a reference point for various operations, such as scaling, rotating, and mirroring objects. In this tutorial, we will explore different methods to select a base point in AutoCAD.

Method 1: Using the “Base” Command

The easiest way to select a base point is by using the “Base” command. To do this:

  1. Type “BASE” in the command line and press Enter.

  2. AutoCAD will prompt you to “Select base point:“.

  3. Click on the desired location in the drawing area to set the base point.

This method allows you to quickly set a base point without any additional steps or settings.

Method 2: Using Object Snaps

If you want more precision while selecting a base point, you can use object snaps. Object snaps help you align your cursor with specific points on existing objects. Here’s how you can use object snaps:

  1. Type “OSNAP” in the command line and press Enter.

  2. The Object Snap dialog box will appear. Enable the desired object snaps, such as “Endpoint“, “Midpoint“, or “Intersection“.

  3. Type “BASE” in the command line and press Enter.

  4. Move your cursor near the desired object snap point, and AutoCAD will automatically snap to it.

  5. Click to set the base point.

Using object snaps ensures that your base point aligns perfectly with existing geometry, making your design more accurate.

Method 3: Using Object Tracking

If you need to select a base point relative to an existing object, you can use object tracking. Object tracking allows you to track along specific paths or distances. Here’s how to use object tracking:

  1. Type “OTRACK” in the command line and press Enter.

  2. The Object Snap Tracking dialog box will appear. Enable “Polar” or “Ortho” tracking based on your requirement.

  3. Move your cursor along the desired path or distance, and AutoCAD will track it.

This method is particularly useful when you need precise control over the location of your base point in relation to other objects.

In Conclusion

Selecting a base point is a crucial step in AutoCAD as it affects various design operations. In this tutorial, we explored three different methods to select a base point – using the “Base” command, object snaps, and object tracking. Each method offers different levels of precision and control, allowing you to choose the most suitable approach for your design needs.

By using these methods effectively, you can ensure that your base points are accurately placed, resulting in well-executed designs in AutoCAD.
