Which is the Best and Easy to Use for Metal Building Design Software

Have you ever searched for a free CAD software to design parts, in particular for sheet metal?

If so, you'll know that's difficult because there are many software tools that might look like the coolest and simplest solution, but after you finalize your design, you realize it's just not really suited for the goal. (looking at you, Blender!).

Finding a CAD solution specifically for sheet metal products design is a bit tricky because you'll either need a simple 2D CAD system, or ideally: a parametric or direct 3D modeler that allows you to design flanges and work with bend deductions: In short, a CAD-system with a dedicated sheet metal module.

If you intend to use your CAD software just for some basic part design or learning the skills, you're in luck – you can do this for free! There are few strong options out there such as FreeCAD, Onshape and Fusion360

But if you're looking to design sheet metal for professional applications, chances are you'll face some limitations in the free editions. That being said, let's dive into how you can get started today.

This article will show you five free CAD software programs that are easy to use, outstanding at their jobs, and suitable for 2D or 3D sheet metal design.

What is CAD software?

Computer-Aided Design (CAD) software is an interactive digital design tool used to make models for engineering. It permits to draw 2D/3D models that can be used for engineering documentation, as well as the models that are used for CNC Manufacturing.

It helps users create designs in either 2D or 3D so that they can visualize the construction.

CAD has replaced manual drafting often, resulting in significant productivity improvement by eliminating many manual actions and streamlining the design process. As well, it helps engineers make their designs more accurate and easier to modify for later improvements.

The use of CAD software has grown exponentially in the past two decades because it covers many aspects of design, including architectural design, mechanical engineering, product design, and more.

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.

What are requirements for Sheet Metal Design?

It is hard to find the best free CAD software for metalworking in 2022.

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.

For example, if you are designing simple folded sheet metal parts, you are only needing to design some flanges with rounded radii: a simple sheet metal module.

What are the most important factors in the selection of a CAD software?

First, you could draft in an old-school way and do it all in 2D. Many legacy manufacturers still work in 2D DWG and DXF drawings. So, there is a high chance you'll be fine with just drafting some 2D designs quickly. The saying might go like this: if it ain't broken, don't fix it, right?

Another reason for this is that most metalworking schools still teach students how to design flat patterns themselves, calculate bend shortenings based on material thickness, and k-factors. So if you're lucky enough to know your way around this, you should be fine off with a free 2D CAD system.

But if you're looking for a modern, faster way, you probably are better off with a 3D CAD solution.

Requirements for a 3D CAD solution:

Let's take a look at some of the most important factors that should be considered when making the right CAD software decision:

• Design in X Y and Z planes
• Ability to fold and unfold flanges
• Ability to configure radii for flanges (Tip: a radius of 0 is not possible)
• Ideally: Configuration of k-factors

We can often summarize this as a dedicated sheet metal module, or workbench.

Now that we know what the software needs to be functional, let's look at the different versions of free software since not all are truly free or created equal.

Student, Personal, Open Source or Paid?

CAD software for students

If you're a student, there are many more options for you than we have listed here below.

Students can typically get a student license to the larger CAD-software systems such as the most popular SolidWorks Student edition, CATIA Student, CREO student edition, and Inventor Student Edition, completely free of charge.

All you need is your university email address and sometimes a university name. This might take a bit longer, but in the end, you can get the best solutions to learn with for free.

In most cases, if you're a student, you might be better off learning the larger CAD-software's and jumping straight into them.

If you're not a student yet or if you're just learning by yourself without being signed up for a university, you can still apply for free trials and access most of the tutorials and documentation.

CAD software for personal use

Personal use usually means you can't give out copies, use them for business purposes, assign them to an organization, or make money from it. It's just for you.

Free for personal use means the same thing in this context, so you can download the software and use it, but it should not be installed on your company's computers.

…. and yes, this also means that personal use is not meant for your next little shop on Etsy.

Personal use can be used for your hobby and if that's what you're looking for, then you're in luck since a few CAD-vendors like OnShape or the free FreeCAD will be perfect for this application.

Open-source software

Open-source software is software that uses an open-source license, which allows the user to run, study, share and improve the software.

This means that the code behind the software is freely available, and the software is created by and for the community. All open-source software can be used for commercial purposes, and the Open-Source Definition guarantees this. You can even sell open-source software.

In this article, we will explore FreeCAD as an example of this

When to consider a paid alternative

For professional use, you're better off with a paid solution because your product has extensive support, and higher-end CAD solutions come with significant extra functions.

There is a huge gap in price between the most expensive and free solutions. For metalworking companies, it's often worth considering cheaper licenses and software.

For example, you should then look at SpaceClaim, BricksCAD, and SolidWorks all of which come with a FREE trial (click on the links to find out more)

SolidWorks also offers a hobbyist license through EAA memberships, which is the cheapest non-commercial license. And Fusion 360 is also available at reasonable price tags.

You might also want to consider paid solutions that don't break the bank, such as Alibre

In the near future, we'll publish another article about professional CAD software for sheet metal. Stay tuned for this one. Meanwhile, have a look at my free guide:

Fusion360 For Personal Use

Overview

• Operating system: Mac OS, Windows
• License: Free for personal, Yearly subscription professional use
• Sheet Metal Module: yes, dedicated functions.

Fusion 360 is a cloud-based 3D CAD/CAM/CAE software first released by Autodesk in 2013.

It is by many engineers considered the best CAD software around because of its advanced features. In our opinion, this is true in many regards, but it does have a lot of competition from Onshape and has some limitations in the free version.

Fusion 360 is more advanced than FreeCAD in many ways, which is no surprise with having such a large company behind it. The user interface looks a lot like the popular inventor CAD-software.

It is often easier to learn and use than other systems. While Fusion 360 can do almost everything that SolidWorks and Onshape can do, at the end of the day, it all comes down to what the purpose of your software is.

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.

Fusion 360 is free for personal use. In our opinion, the free option is a bit limited these days, but if you just want to design parts in it, it'll probably do what you want. Limited file output types and access to machining strategies on the free tier, though.

One tip from our side: make sure to check the privacy settings of the software once you install it, since it sends a lot of diagnostic data to Autodesk's servers. You can uncheck these from the settings menu.

Best Free 2D CAD software

If you don't feel comfortable working in 3D and just want a simple 2D solution, we have selected two pieces of software for you that you should have a look at.

Both can be used for free and allow you to make 2D designs. For example, if you want to edit flat patterns, or just make 2D laser cutting files, such as editing DXF files.

LibreCAD

Overview

• Operating system: Windows, Apple and Linux.
• License: Free, open source

LibreCAD is a free Open-Source CAD application for Windows, Apple and Linux. Support and documentation are free from our large, dedicated community of users, contributors and developers.

It comes with partial support of the Autodesk DWG format (importing only), but full support of the Autodesk DXF open format (import and export). LibreCAD uses this as its main format.

You can easily use it for the most common 2D operations: Line, circle, arc, polyline, spline. As well, Entity modification: move/duplicate, mirror, scale, offset, trim, fillet, etc.

Plugins are also developed to ease some tasks. The user interface is available in several languages.

The best thing about this is that it has a great community, and you can count on regular support. As mentioned, it's 2D, so you'll have to know some in's and out's about design sheet metal parts.
