$8.00/month

Steel Frame & Weldments adds a complete structural framing workflow to Autodesk® Fusion®. It is built for fabricators, welders, furniture builders, machine builders, mechanical designers, and anyone who needs to create welded frames from sketches instead of manually sweeping and trimming every member.
With the Frame command, you sketch the centerlines of a structure, select the lines, arcs, splines, or model edges, choose a profile, and let the add-in generate the members. A frame can contain multiple groups, so primary posts, rails, braces, curved members, and secondary members can each use their own profile, orientation, and joint behavior.
The frame system supports common end treatments such as End Miter, End Butt1, and End Butt2. Butt joints can use a simple cut or Coped cut, allowing members to be trimmed by a flat plane or notched to the body they contact. Group order controls joint priority: primary frame groups can be created first, while later brace or secondary groups are trimmed to them. When a single corner needs different treatment from the rest of its group, a per-corner override gives that one corner its own corner type and trim type without splitting the group in two. This makes it easier to build practical shop-ready frames with predictable member interaction.
For laser-cut tube fabrication, the Tab / Slot command adds a self-fixturing tab on one member and a matching through-wall slot on the other, so parts locate themselves for welding and the weld is the only step left. The tab is a straight finger of the member's own wall running along its axis, which is the shape a tube laser can actually leave standing. It works on square and rectangular tube, round tube (where both the tab and the slot follow the tube's curve), flat bar, angles, channels, and custom sketch sections. The slot can be cut square through the wall for any tube laser, or angled to follow the tab where a 5-axis or bevel head is available. Tab position, width, thickness, length, and per-side slot clearance are all adjustable.
Each group has full orientation controls, including anchor point, rotation, X/Y offset, 180-degree flip, optional weld gap, and optional extension behavior. Members can also be created as separate components, which is useful for organizing larger frames, using Fusion Drawing tools, and reviewing individual parts.
Created frames are editable. Select an existing frame member, reload the stored frame definition, adjust profiles, groups, orientation, or options, and rebuild the frame in place. Tab/Slot joints, gussets, and end caps recorded on that frame are re-applied to the rebuilt members automatically. Items you deleted by hand stay deleted, and anything that cannot be re-applied is reported after the build instead of failing silently.
The add-in also includes tools for single members, gussets, end caps, tab/slot joints, notch cuts, miters, trim/extend operations, profile library management, and custom profiles from sketches. Gussets and end caps include preview and edit/rebuild support.
The profile library ships over 600 sizes in 35 families across four standards. EN/DIN covers IPE, HEA, HEB, UPN, equal and unequal angles, T sections, RHS, SHS, CHS, round tube, and flat/square/round bar. ANSI/AISC covers W, C, angles, HSS, Pipe, and bar. JIS covers H, C, STKR tube, and STK pipe. Aluminium extrusion covers T-slot 20, 30, 40 and 45 series, V-slot 20 series, C-Beam 40x80, and imperial 80/20 sizes (1010, 1020, 1030, 1515, 1530, 3030). The aluminium profiles are the real extruded outline, with slots, X core, and centre bore, so coped joints, notches, and end caps follow the true wall instead of a plain box. Parametric sections import and export as CSV, so users can add custom standards, supplier sizes, or company-specific profiles, and any closed sketch can be captured as a custom section.
For fabrication review, the Cutting List command exports CSV data and a printable PDF containing a model overview with item balloons, a cut list table, and per-item detail sheets with long/short-point lengths and end-cut angles for frame members, curved members, gussets, and end caps. Ends carrying a self-fixturing tab are called out as such. For large projects or highly detailed production documentation, users can continue with Autodesk Fusion Drawing tools using the generated components. Cutting List output units (mm/cm/m/in/in-fractions/ft, defaulting to the document unit).

Frequently asked questions (FAQs)

What else should I know about this product?

Requirements: Fusion for Windows. Internet access is used for Autodesk entitlement and license verification.

Included tools: Frame, Member, Gusset, End Cap, Tab / Slot, Notch, Miter, Trim/Extend, Manage Library, Profile from Sketch, Delete Profile, Cutting List, and Info.

Profile library: over 600 sizes in 35 families across four standards. EN/DIN (IPE, HEA, HEB, UPN, equal and unequal angles, T, RHS, SHS, CHS, round tube and bar), ANSI/AISC (W, C, angles, HSS, Pipe and bar), JIS (H, C, STKR tube, STK pipe), and aluminium extrusion (T-slot 20/30/40/45 series, V-slot 20 series, C-Beam 40x80, and imperial 80/20 sizes). Parametric sections import and export as CSV so users can add custom standards, supplier sizes, or company-specific profiles. Aluminium extrusion profiles and sketch-captured sections are stored as geometry rather than parameters, so they are not part of the CSV round trip.

Cutting list output: CSV data plus a printable PDF containing a model overview with item balloons, a cut list table, and per-item detail sheets with long/short-point lengths and end-cut angles, covering frame members, curved members, gussets, and end caps. Cut angles can be reported as face angles or saw settings. For detailed production drawings, use Fusion Drawing tools with the generated components.

Privacy: The add-in uses Autodesk entitlement information and the publisher license service to verify access. It does not collect design files or project geometry. See the privacy policy for details.

AI / MCP: The add-in includes an optional local Model Context Protocol server for approved AI clients. It is disabled by default and starts only if the user turns it on. When enabled it listens on the loopback interface (127.0.0.1) only, on a random port with a fresh random token each session, exposes a fixed set of read and create operations, executes no arbitrary code, and requires an active license or trial for any model change.

Are there any known issues with this product?

Windows only in this release.
Very large frames with many members, curved members, and coped joints may take longer to preview or rebuild.
Keep Capture Design History enabled for the best edit/rebuild behavior.
Tab / Slot requires both members to have been created by this add-in, and the tab member's end must already reach the wall of the slot member.
The CSV/PDF cutting list is intended for quick fabrication review and estimating. For detailed production drawings, use Fusion Drawing tools.
