Fusion 360 Tutor: Model Creation Expert

I'm currently learning to use Autodesk Fusion 360 and require someone with expertise in this platform to guide me through a problem regarding model creation. Specifically, I'm having difficulty in creating and editing features within the software. Key Problem: • The task I'm struggling with involves shelling out two different bodies that have been linked using the loft command but the top requires a different thickness from the bottom without altering the overall design. Please refer to the attached images for better explanations. The ideal candidate: • Should have comprehensive knowledge and skills both in Fusion 360 and its functions, particularly in model creation. • Needs extensive experience in creating and editing features within the 3D modeling tool. • I need someone patient, who can guide me through troubleshooting this specific problem and explain to me how I can fix this for myself so I don't run into this problem again. • If you have a knack for teaching complex concepts in a simplified manner, you are the perfect fit. I wish to understand this aspect deeply, hence it'll be a bonus if you can assist in creating a workflow that I can follow to understand and execute similar tasks in the future on my own. Let's enhance my Fusion 360 skills one query at a time.
