How to Learn Fusion Form Operations: From Basics to Practice (CAD/Modeling)
I find the Fusion [Form] environment useful when I want to create
smooth exteriors, grips, or bottle shapes and similar items.
Rather than building up with dimensions,
it is like
shaping clay while moving faces, edges, and vertices.

🔧Start with [Edit Form]
The first thing to learn is [Modify] > [Edit Form].
Select T-Spline faces, edges, or vertices, and adjust the shape by moving, rotating, or scaling them.
The recommended order for learning is:
Create the overall shape with faces
Refine the contours and tension with edges
Fine-tune the details with vertices
This flow feels easy to understand.
Also, you can add new geometry by holding down the Alt key on Windows or the Option key on Mac while dragging.
📘 Check the shape in display modes
In Form, it is important to check not only the appearance but also the structure.
Switching between [Box], [Control Frame], and [Smooth]
makes it easier to check control points and the final shape.
When the shape becomes distorted,
it is a good idea to check [Repair Body] or [Uniform].
🚰 Practice with the official tutorial
If you want to learn systematically, the Autodesk official help tutorials are reliable.
I think starting with "Create and Modify T-Spline Forms" is a good way to grasp the basic operations.
Next, moving on to the water bottle, watering can, and creation using reference images will bring you closer to practical free-form modeling.
Tutorial order
If you are starting out,
"Create and Modify T-Spline Forms" is recommended.
In this tutorial, you can learn how to create T-Spline forms using box, revolve, sweep, and loft, as well as how to modify forms, change display modes, and insert edges.
Next, by proceeding to "Create a Water Bottle",
you can learn a more practical workflow, including creating basic shapes, the spout, the bottom, adding thickness, and checking volume.
As a further application, "Create a Watering Can" is also effective.
In this tutorial, because you create a shape with a handle and a spout,
you can learn form creation that combines
splines, sweeps, construction planes, elliptical profiles, and lofts.
If you want to create a shape using an image as a base,
"Creating T-Spline Forms Using Reference Images" is a good reference.
You can learn the process of inserting a canvas image and
editing a T-Spline box to match that image.
⚠️ Points to watch out for
If you twist the faces too much or cause them to self-intersect,
it may become difficult to convert to a solid later.
Since you can move things freely, I feel it is important to be conscious of keeping the flow of the faces clean.
✅ Summary
For Fusion form operations, it is best to first get a feel for it using [Edit Form],
and proceed while checking the shape in display mode.
If you try the official tutorials in order,
I think you can learn from the basics to practice without difficulty.
