Are you struggling to figure out how to get a bottom view in AutoCAD 3D using the base command? Well, look no further! I'll walk you through the steps to achieve this effortlessly.

Step 1: Open your AutoCAD 3D drawing and make sure you are in the 3D modeling workspace.

Step 2: Navigate to the 'View' tab on the ribbon and select the 'Base' command from the 'Views' panel.

Step 3: Once the 'Base' command is activated, you will be prompted to specify the base point. This is the point from which the view will be projected.

Step 4: Choose a point on the bottom surface of your 3D model as the base point. This will define the bottom view orientation.

Step 5: After specifying the base point, you can then adjust the view orientation by using the grip controls or inputting specific values for rotation, elevation, and distance.

Step 6: Once you are satisfied with the view orientation, press 'Enter' to confirm and generate the bottom view.

And that's it! You have successfully obtained a bottom view in AutoCAD 3D using the base command. This method is quick and efficient, allowing you to showcase the bottom details of your 3D model with ease. Practice this technique and incorporate it into your 3D modeling workflow to streamline your design process and improve visualization. Happy designing!
