Hey there, design enthusiasts! Today, I'm going to show you how to create an OBJ file in Adobe Illustrator. If you're ready to take your 3D modeling skills to the next level, keep on reading!

Step 1: Open Adobe Illustrator and create a new document. Choose the dimensions that you want for your 3D object.

Step 2: Draw the shape that you want to turn into a 3D object using the Pen Tool, Rectangle Tool, or any other shape tool you prefer.

Step 3: Once you have your shape, go to 'Effect' in the top menu, then '3D' and select 'Extrude & Bevel'. This option will allow you to extrude your shape and give it depth to create a 3D effect.
