What is IRONCAD?

IRONCAD IRONCAD is a 3D CAD program for industrial design, ranging from machinery and sheet metal to layouts and fixtures. What sets apart from traditional CAD systems is the freedom of choice: you decide for yourself how to model. Design freely using drag-and-drop and TriBall, add constraints and parametric dimensions only where they’re needed, and modify imported geometry directly without a history tree. These methods can be combined within the same , and the entire assembly is contained in a single file. This page shows how hydraulic companies use it. part

SMC Automation, pneumatic systems designed in IRONCAD

This video is SMC Automation’s own presentation of the company: the world’s largest manufacturer of industrial pneumatics, headquartered in Stockholm and with over 9,000 components in stock. Custom valve cabinets, hose routing, and pneumatic schematics are designed at IRONCAD, from the sales representative’s layout sketch to the assembly drawing with a bill of materials.

Three approaches within the same model

You select the method for each part, not for each program.
All three work in the same file, and they can be combined in a single aggregate.

Parametric modeling

For cylinders and blocks that require variant management. Lock the stroke, piston diameter, and port spacing using constraints, and the next size will be recalculated without you having to redraw it.

MOST POPULAR

Flexible modeling

The standard method for assemblies and blocks. Drag and drop pumps, filters, and valves from the catalog, position them using TriBall, and reposition them if the customer wants the connection on the other side. No mandatory constraints.

Direct editing

For suppliers' STEP files of pumps, motors, and valves. Select a surface and drag, add fasteners, and adjust the flange. No history required.

How " IRONCAD " Is Used in Hydraulics

Valve block with channels and cartridge holes

The block is modeled as a solid. Hole patterns, threaded holes, and channels are imported from the catalog with the correct diameter, thread, and depth, and the holes are created as they are placed.

Display the block as transparent, or invert it and view the channels as positive images; that way, you can immediately see if the channels align correctly.

Hydraulic cylinders, standard and custom

The cylinder is built based on stroke length, piston diameter, and connection type, and is saved in the catalog so that the next order starts with a finished cylinder that can be modified.

Seals, lock rings, and bolted joints are retrieved from IC Mechanical. The rendering for the customer presentation is created in KeyShot directly from the model.

Pipes and hoses are routed in the model

Pipes, flanges, and couplings are routed between connections using the Piping tool in IC Mechanical. Hoses are routed as 3D curves with bend radii that match the hose type.

Lengths and items are listed in the bill of materials. If a valve is moved, the pipe moves with it.

Unit with tank, pumps , and purchased components in a single file

The entire unit is contained in a single file: the tank is made of sheet metal, the frame is made of bent sheet metal, and the motors, pumps, and filters are imported from suppliers. The industrial hydraulics team sits in front of the customer and modifies the design directly on-site in real time.

“We can do this without running the risk of all the typical errors that are common in other constraint-based systems,” says Kent Wahlgren, a design engineer at Industrihydraulik.

From 3D to a drawing, using ICD or DRAFT

ICD renders blocks, cylinders, and assemblies with views, sections, ISO-compliant dimensions, and an automatic bill of materials. DRAFT features a traditional 2D interface similar to AutoCAD, for schematics and pure 2D drawings.

Both follow the model when the design changes. The customer receives a 3D model, a diagram, and a drawing from the same project.

Show the customer the solution in 3D and make changes on the spot

Hydnet builds its valve blocks using off-the-shelf components from its own catalogs: cartridge valves, filters, and fittings that are inserted into the block—much like building with Legos.

The block is displayed to the customer in 3D early in the project, with the channels visible through the material. The schematic and the drawing are part of the same solution, which helps reduce errors along the way.

Hydraulic diagrams in DRAFT, in the same project

The schematic is drawn in DRAFT, IRONCAD's built-in 2D environment, using symbol libraries for pumps, valves, filters, cylinders, and accumulators. Custom symbols can be added to the library.

The drawing is included in the same project as the 3D model, opens the customer's DWG and DXF files, and is included in the documentation provided to the customer.
