Claas Kuhnen is an industrial design professor at Wayne State University and he runs his own design consultancy studio. He is also one of the earliest Shapr3D users. Here’s how he fits Shapr3D into his workflow and where he sees the CAD industry heading.
Based on the model and complexity, he usually starts with quick pen-and-paper profile studies of an idea to block out forms and proportions. The initial sketches can be pretty rough and quick. He will quickly put some lines down as a mental note so that he doesn’t forget about an idea.
He often recreates select ideas on the iPad Pro using Concepts, an iOS vector sketching option that lets him use some drafting tools.
Then he creates 3D models in Shapr3D based on his sketch observations. He doesn’t do many perspective freehand sketches anymore, because he feels Shapr3D is faster and more accurate -- the right tool for the job.
Sometimes he makes a quick 3D model, prints it out, and uses it as a template to create hand sketches, for a more accurate result if the model is too complicated or the variations need to be precise.
While brainstorming, he often pins all the sketches onto a wall to see the story behind them, and compare and identify possible design directions.
"One of the greatest things about Shapr3D is that it has many export options. I can easily export models created in the woodshop, at a meeting with a client or a student as a STEP file, then I can send it to the client or continue working with the CAD data in Fusion360."
He loves that he doesn’t have to start from scratch. If he doesn’t need to continue working in Fusion360, he can also export the model as an STL file and send it to a 3D printer to create a prototype.
Fusion360, for example, is very good for creating product assemblies and doing tolerance checks. He can also export a STEP model from Fusion360, load it into Shapr3D on his iPad Pro and continue direct modeling in the app.
"I found this very useful when I leave my studio, or when I go to a client and just don’t want to carry a laptop with me. Modeling with gestures and the Apple Pencil is just so much nicer when you are on-the-go. Much better than a trackpad and a keyboard."
Claas finds today’s CAD applications to be extremely powerful, and is amazed at what can be achieved with them. He can model a product, put it through a physical simulation to stress test it, and then send it to a rapid prototyping machine to build a physical model. Design in the age of 3D printing is getting democratized, and more people have access to the necessary tools than ever before.
Two big problems remain:
Shapr3D makes it possible for Claas to have that experience. It features a very elegant approach to creating sketches and 3D shapes by using an Apple Pencil and gestures with a very minimalistic UI that limits visual distractions and lets you focus more on the creative process.
We need to keep in mind that there are also different types of models:
"Ideally, each model should have its own way to be created. In my studio or model making space, I find Shapr3D the ideal companion to explore my ideas in 3D. And if I need some CAD data, it can be exported to other desktop applications. So you are not locked into Shapr3D, but you can use it as a great tool for the ideation phase, at your desk, in the woodshop, while talking to a client, or while commuting. Later, you can refine the model for manufacturing in a different application other engineers use."
This is how Claas, as a designer, wants to work.
That’s why he started experimenting with Shapr3D from day one. And so far, he likes what it has to offer.
"I like Shapr3D a lot because it gives me some of the industry standard drafting and modeling tools, however in a nice natural pen-and-paper workflow. And since the software also offers the ability to add dimensions and other constraints to sketches, I can be incredibly precise and smart."
