In stainless steel fabrication, design means engineering the part so it can actually be made: setting dimensions, material grade, joint and weld details, finish and tolerances, then checking that the workshop can cut, form, weld and finish it as drawn. It is not graphic design or product styling. This stage matters whenever you need a bespoke stainless item — a frame, tank, duct, pipework run or enclosure — and it usually starts from your sketch, sample or drawing rather than a finished CAD model.

What the design stage covers

Design work in a fabrication shop turns an idea into instructions the workshop can follow. That normally includes:

• Geometry and dimensions — overall sizes, bend radii, hole positions, and how parts fit together.
• Material grade — which stainless grade suits the environment (for example a grade chosen for corrosion resistance or for weldability). The fabricator should confirm the grade rather than assume it.
• Joint and weld details — where seams run, whether welds are visible or dressed, and how access is provided for the welder.
• Finish — the surface treatment required, such as a brushed, polished or other finish, and which faces are cosmetic.
• Tolerances — how accurate the finished part must be, since tighter tolerances generally mean more work.

How design decisions affect manufacture and cost

Most cost and lead-time differences between two apparently similar parts come from design choices, not from the amount of steel:

A design that is easy to weld and finish is usually cheaper and faster than one that only looks simple on paper.

Typical design-to-manufacture workflow

1. Brief or sketch — you provide a drawing, sketch, photo or sample, plus what the part must do.
2. Design review — the fabricator checks feasibility, suggests changes, and confirms grade, finish and tolerances.
3. Agreed drawing — a dimensioned drawing or model is signed off before cutting starts.
4. Fabrication — cutting, forming, welding and finishing to the agreed drawing.
5. Inspection — the finished part is checked against the drawing and finish specification.

The design review step is where most problems are caught cheaply, before any material is cut.

Common design mistakes that cause delays

• Missing dimensions, or dimensions that do not add up.
• No material grade specified, or a grade that is hard to weld or form.
• Finish left undefined, so the workshop guesses.
• No tolerance stated, leading to disagreement at inspection.
• No allowance for weld distortion on large or thin panels.
• Cosmetic faces not marked, so they get scratched during handling.

Questions to ask a fabricator at the design stage

• Which grade do you recommend for this environment, and why?
• Can this be made as drawn, or would a small change reduce cost or lead time?
• Which faces are cosmetic, and how will you protect them?
• What tolerance can you hold, and how will it be checked?
• Will welds be visible, dressed or hidden?
• What do you need from me before you can quote and start?

Getting clear answers to these before fabrication begins is the practical way to avoid rework and unexpected cost.

Cascadeur is a 3D animation software built specifically for character animation, combining traditional keyframe work with AI-assisted tools for posing, inbetweening, and motion generation. It fits workflows where you need to block out or refine character motion — game combat animations, previz, mocap cleanup — rather than general-purpose 3D modeling or rendering. You can evaluate it through a free trial before committing.

What Cascadeur Is Designed For

The software targets a specific slice of the animation pipeline: the motion of humanoid and quadruped characters. Its stated use cases are:

• Mocap cleanup — fixing and editing motion capture data, including preventing foot sliding, knee pops, and geometry penetration.
• Previz — rapid blocking of animation for planning.
• Animation editing — making changes through Animation Layers.
• Game prototyping — producing combat, locomotion, and idle animations for games.

One documented production example: Nekki created the combat animations for Shadow Fight 4: Arena in Cascadeur. The game has surpassed 50 million downloads and 1.8 million reviews on Google Play alone.

The Core AI-Assisted Tools

Cascadeur's distinguishing feature is that its AI tools are meant to be editable rather than one-click black boxes. The CTO, Alexander Grishanin, has argued that editable AI matters more than one-click generation — worth keeping in mind if you need to iterate on results rather than accept them.

Inbetweening

AI interpolation that generates motion between your keyframes. You set the key poses; the system fills the gaps, which you can then adjust.

AutoPosing

An AI system that produces natural poses when you move fewer control points. Instead of rotating every joint, you move a few and the system infers a plausible full-body pose.

Ragdoll

A procedural tool that makes characters react to impacts, simulate falls, and handle collisions.

AutoPhysics

Displays a physically accurate result for the character, letting you quickly adjust secondary motion, inertia, and similar properties.

AI Motion Generation

Generates animation types including running, jumping, combat, acrobatics, and idles. This is generation as a starting point, not a final output — the editable framing matters here.

Rigging and Retargeting

• Rigging: drag-and-drop the joints of your character to generate a rig automatically, for both humanoids and quadrupeds (cats, dogs, horses, etc.).
• Retargeting: copy and paste animation between different characters regardless of skeletal structure or proportions. Quadrupeds get one-click retargeting.

How It Fits Into an Existing Pipeline

Cascadeur works with common interchange formats, which determines whether it can slot into your current toolchain:

For Unreal Engine users, UE Live Link streams animation directly into the engine, with changes updating in real time. That's the most direct integration path if your target is a UE project.

When Cascadeur Is a Good Fit — and When It Isn't

Choose it if:

• Your work is character motion: combat, locomotion, acrobatics, idles.
• You need to clean up mocap data and fix common artifacts like foot sliding.
• You want AI assistance that stays editable rather than generating a final clip you can't adjust.
• You're targeting Unreal Engine and want live streaming of animation changes.

Look elsewhere if:

• You need general 3D modeling, texturing, or rendering — Cascadeur is animation-focused.
• Your work is 2D animation or sprite-based.
• You need a fully automated one-click motion pipeline with no keyframe editing.

How to Evaluate It

1. Go to the plans page and start the free trial.
2. Import a character in a supported format (.FBX, .DAE, .GLB/.GLTF, or .USD).
3. Use drag-and-drop rigging to generate a rig, then test AutoPosing by moving a few control points and checking whether the inferred poses are usable.
4. Set two keyframes and run Inbetweening to see whether the generated motion matches your intent.
5. If you use Unreal Engine, connect UE Live Link and confirm that edits update in the engine in real time.

The trial is the practical test: the value of an AI-assisted keyframe tool depends on whether its generated poses and inbetweens are close enough to your target that editing them is faster than animating from scratch.
