SketchUp vs Shapr3D:
Which 3D design tool should you choose?

Shapr3D and SketchUp are both 3D design tools known for their ease of use and low barrier to entry. However, there are a few major differences between the two.

Shapr3D is an MCAD (mechanical computer-aided design) tool. It uses boundary representation (b-rep) to create precise geometry for manufacturing through 3D printing, CNC milling, and other methods.

SketchUp, on the other hand, is a surface-based 3D modeling tool often used for conceptual design and layouts. As a mesh-based modeler, it uses polygons to represent geometry. Because polygons can only approximate curved surfaces, not define them mathematically, SketchUp lacks the precision often required for manufacturing.

3D-printed models need to be watertight, or manifold, meaning there are no small holes or gaps in the geometry. A non-manifold model, or one that has gaps, may cause errors or failed prints.

Shapr3D excels at producing precise, watertight models thanks to its Siemens Parasolid geometry engine. SketchUp’s mesh-based modeling requires a special extension to fix geometry errors before exporting, and it does not natively export 3MF, one of the most popular modern formats for 3D printing.

Designing furniture often requires you to work with more organic shapes, such as rounded edges and curves. Shapr3D’s b-rep modeling allows you to fillet and chamfer edges, creating rounded or beveled corners. SketchUp’s mesh-based modeling lacks this capability, and curves aren’t represented precisely.

Shapr3D also uses a history-based parametric modeling approach, which automatically updates related parts when you change a model’s parameters to preserve design intent. This reduces errors and improves efficiency, which is crucial in furniture making, 3D printing, and manufacturing.

SketchUp does not have native parametric modeling, though you can use an extension to add this capability. If you want to edit geometry in SketchUp, you may need to rebuild part of your model, which increases the likelihood of errors.

When you’re designing parts to be manufactured, precision matters. Shapr3D’s Parasolid foundation is an industry standard, allowing users to create highly accurate 3D models of complex parts.

If you love 3D modeling on the iPad with an Apple Pencil, Shapr3D offers full modeling capabilities like what you’d find on our desktop Mac and Windows software.

SketchUp’s iPad version has a more limited toolset and no V-Ray rendering. Plus, if you’re used to using extensions on the desktop to improve your workflows, these extensions aren’t supported on iPad.

SketchUp’s 3D Warehouse is a well-known, useful feature for interior designers and architects. You can easily choose from a library of pre-built objects to add to your layout.
