Before you can create a 3D object, the first step you must do is to create a 2D sketch. This is a crucial initial step in the process of generating a 3D object.
1. Creating a 2D sketch: In a 2D sketch, you outline the basic shape or design of the object you want to create. This serves as the foundation for constructing the 3D object.
Once you have successfully created the 2D sketch, you can then proceed with extruding or adding dimensions to convert it into a 3D object.
Therefore, the correct step to take first before creating a 3D object is to create a 2D sketch.
