I just had the idea that one could use the sheet metal workbench for creating sewing patterns.

There are some similarities between sewing and creating things from sheet metal (creating a volume from flat material), so this workbench could be helpful.

has anyone ever tried that?

Apart from that, what are your experiences with the sheet metal workbench?

Hi All. Is it possible to use sheet metal on an existing object. I have been able to add bends and rips but cannot get it to unfold. My base flange is on it own plane that is not one of the standard planes. Would this be causing the error?

To get my object (before adding rips and bends) I used the "make thick" solid to make a hollow object with wall thickness of the sheet metal I intend to use. The base flange is at at a 15 diagonal angle across the rectangular box. so I am guessing this is throwing every thing off. I am not sure how to use one of the sides as a base flange. (If that is even possible)

In this Tutorial I have explained How to Model Sheet Metal Part using FreeCAD Sheet Metal Workbench. This tutorial is designed for beginner level FreeCAD user. In this tutorial I have covered basics of Sheet Metal Workbench like sheet metal thickness, Bending Radius, Flange Direction, Multi Transform Pattern etc. I am also providing 2D drawing and source file used in this tutorial so that beginner user can practice themselves and refer my FreeCAD file in case of any doubt.

Today, manufacturers use modern PLM and PDM systems and store their designs on the network or in the cloud. CAD-files are typically also used to send directly to CAM-systems to create NC-codes, for example for sheet metal laser cutting or sheet metal die bending.

As a consultant, I have been on the lookout for the best CAD software that will fit the needs of my larger clients. But I know that not everyone is looking for the Rolls-Royce of sheet metal design solutions. Sometimes you just want something simple, and ideally free.

FreeCAD is the only truly open-source software that also comes with a sheet metal workbench to design sheet-metal parts. The library is still being developed by enthusiasts all around the world, and therefore it makes a fantastic starting solution.

Onshape saves you time with Parametric Modeling 2.0, a fundamentally better way to model using multipart design, configurations, simultaneous sheet metal tools, standard content, and managed in-context design.

On another note, the software is great for mechanical or technical designs, and the sheet metal functions are well established. It works on both cloud and device. Thus, if you do not have an internet connection you could work on your project as well.

I help sheet metal companies to higher productivity by automating processes. With over 10 years of experience in the metal industry and automation, my customers call me a thoughtful, experienced specialist with in-depth knowledge of the industry.

Like freecad and fusion. The sheet metal option gives you the power to create sheet metal objects (boxes for example) with flange options, flatten, open close etc. Are you familiar with sheet metal in fusion or free cad. If so then this is what I am asking and what I strongly advise sketchup to do, This would make it truly the best program.

Sheet metal is one of the most convenient object types for a computational geometer. In most cases, it is possible to recover all features from a "dumb" STEP file (or any other feature-free format) and unlock further processing of a model in a direct manner. The simplicity of a sheet metal part is due to the types and specific order of its faces. Specifically, planar sheets follow cylindrical bends and vice versa. By visiting sheet metal faces recursively, one can distinguish both sides and deduce the object type (e.g., flat plate, folded sheet metal, or tube).

There are quite some tools that allow us to design and manipulate sheet metals. As a big fan of the direct editing paradigm (that's likely because I am not an engineer and simply appreciate responsive UI), I'd pay particular attention to the software packages capable of recognizing "dumb" models for subsequent unfolding:

Unlike SpaceClaim, FreeCAD (ver. 0.18) seems to leave possible self-overlappings of a flat pattern undetected. However, that's not a big deal, as such verification (based on OpenCascade's Booleans) can easily be added (if someone wishes to contribute that to FreeCAD). We will touch on some of the nuances of sheet metal processing in the future series of MG.

Unfolding in SpaceClaim becomes available once a part is recognized as sheet metal. SpaceClaim allows for identifying certain feature types, such as louvers, bridges, hems, etc. Hence it's quite powerful, although I always struggle a bit with the UI workflow (i.e., which buttons to click in what order).

Our in-house SDK recognizes different sheet metal features without asking the user to enumerate their types beforehand explicitly. Unlike FreeCAD and seemingly SpaceClaim, it also counts the detected features and derives some handy props such as the stock area, its perimeter, etc.

First off, like in any other geometric algorithm, there should be a driving idea. Without such, any algorithm facing high enough "selection pressure" is doomed at becoming a big ball of mud impossible to maintain. The key idea behind sheet metal unfolding is splitting up the CAD model in two sides. Once you're armed with AAG, graph theory's formalism starts serving you and shortly pays off.

The graph should be splittable into a couple of components representing the upper and the lower sides of sheet metal. The graph nodes to exclude for such splitting form up a chain of "thickness faces." That idea is clear and simple yet powerful to sustain a lot of realistic cases.

Both Design Tech (@DTatGIS) and cj @ scalar (@ScalarElectric) on twitter advised me that Fusion 360 has a sheet metal feature. After a bit of searching I discovered it was launched in August this year. From the help pages it seems to have all the right capabilities. Thanks Emma Lovelace and Tharin for clarifying that I can sign up for the Start-Up/ Enthusiast licenses.

FreeCAD is a free and open-source 3D computer-aided design (CAD) software application. It is intended for use in mechanical engineering, architecture, and other fields that require the creation of detailed 3D models.The user interface (GUI)The user interface of FreeCAD is designed to be user-friendly and easy to use, with a layout that is similar to other 3D CAD software applications. It consists of a main window with a series of toolbars and panels for accessing different features and settings.In the main window, you can see a 3D view of the model that you are working on, as well as a series of toolbars and panels that allow you to access different tools and options. For example, the "Model" panel allows you to select and edit the components of the model, and the "View" toolbar allows you to change the view of the model, such as by zooming or panning.The main window also includes a series of tabs and panels that allow you to access different features of FreeCAD. For example, the "Part Design" tab allows you to create and edit 3D solid and surface models, and the "Drawing" panel allows you to create 2D technical drawings of the model.The menu bar at the top of the window allows you to access various features of FreeCAD, such as the option to import or export models or to customize the settings of the application.What you can do with FreeCAD3D modeling: FreeCAD allows you to create and edit 3D models of objects, including components, assemblies, and construction details.Part design: FreeCAD includes tools for creating and editing 3D solid and surface models, such as for creating mechanical parts or architectural components.Assembly design: FreeCAD allows you to create assemblies of multiple parts and to visualize the relationships between the components.Drawing creation: FreeCAD includes tools for creating 2D technical drawings of 3D models, such as dimensioning, annotations, and views.To sum it upOverall, FreeCAD is a powerful and feature-rich 3D CAD software application that is suitable for a wide range of design tasks, such as mechanical engineering, architecture, and more.
