I'm on the hunt for a good CAD software that I can use for woodworking projects, particularly for modeling loads. I'm interested in being able to choose different joining styles, like screws or wood joinery, and have the software provide feedback on the stiffness and sturdiness of the furniture I design. I've seen discussions about this topic come up repeatedly, and I even found an old query on calculating structural loads. With a background in civil engineering from my dad, I'm wondering if mechanical CAD software is the right tool to help calculate the weight capacity for wooden structures, or if I could rely on general guidelines instead. For future projects, like a bed frame that needs to support two people and a few pets, I want to make sure it won't collapse. I've heard good things about Fusion 360, particularly concerning its capabilities. But can I really trust it for calculating loads and ensuring my designs are solid?

While Fusion 360 has a steep learning curve, learning that software could offer you valuable skills in the long run, especially if you enjoy diving into new things. Just remember, if this is your first experience with CAD software, be prepared to invest some serious time into learning the fundamentals before you can effectively use it for woodworking projects. But if you're up for the challenge, go for it! Just don't expect to become a master overnight, but it will certainly pay off in future designs!
As a structural engineer, I think you're overthinking it a bit. Wood is actually much stronger than most people realize, and as long as you follow some common best practices, you shouldn't have to worry too much about structural integrity. Instead of getting caught up in modeling loads, focus on understanding those best practices. For example, make sure your bed slats rest on actual vertical supports rather than relying on screws to carry all the weight. People often make the mistake of undersizing their fasteners. So, stick to what works and avoid trying to reinvent things! Most likely, if you're following standard designs, your furniture will hold up just fine. Plus, I'd advise against using deck screws or drywall screws—stick with proper wood screws for structural stuff.
What you're looking for is often referred to as Finite Element Analysis (FEA). For straightforward projects like a bed or desk, the effort required to set up a model often outweighs the benefits. Unless you’re working on something high-stakes or cutting-edge, it makes more sense to focus on overbuilding and following tried-and-true guidelines. Fusion 360 is a powerful tool and can certainly assist, but if this is all new to you, it might feel overwhelming at first over time. Just be aware that you might spend more time learning it than necessary. If you do dive in, consider starting with basic tutorials to get the hang of it without getting too frustrated!
Honestly, using consumer-grade software for load analysis can be tricky, especially if you don't have training. If you're just starting out, it might be better to rely on established rules of thumb and existing designs rather than diving deep into software modeling. In woodworking, there are so many variables that it's hard to get accurate models. Keep it simple: when in doubt, overbuild! You want sturdiness, not to dive into potentially misleading computations.
Definitely! And just a note: while it might seem daunting, you'll find a wealth of tutorials online that can ease that learning curve. Just take it step by step, and you’ll get the hang of it! Don’t rush too much, and follow along with simple projects first.
