As a Rhino user, you will find a lot of things familiar in Shapr - with one major difference:
- While Rhino is a surface modeling tool, Shapr is a solid modeling tool. (Learn more about the differences following this link)
This means that with Shapr it is much easier to create manufacturable, watertight models. For example, creating fillets in Rhino can be quite painful, but it's really easy in Shapr. Thanks to the robust data exchange capabilities of Shapr, you will be able to use Shapr and Rhino together:
- you can export and import STEP files from and to Shapr and Rhino.
However, in most cases models created in Shapr are more accurate than Rhino, thanks to the underlying industry standard modeling engine (Parasolid).
Even though there are familiar workflows in Shapr, you'll spot a few important differences as well.
Designing with solid modeling requires a slightly different mindset compared to surface modeling. For example - besides other differences - solid modeling means that quite a lot of things, that should be done manually with surface modeling, will be handled automatically in Shapr. For example, if you want to change the radius of a blend, you can simply select it, and change its value, and Shapr will automatically rebuild your object.
Also, you can easily Move, Rotate, Offset or apply any kind of transformation on a face of a solid body, and Shapr will automagically rebuild the surrounding faces, guaranteeing that your body will remain a solid, watertight object.
You can also remove an arbitrary feature of your body, and Shapr will always guarantee that your solid bodies will actually stay solid bodies.
And here is the most magical thing about Shapr: all of these operations work on imported models as well. This means that if you built a correct solid model in Rhino, you will be able to edit it in Shapr just like that. All you have to do is to export your files to a STEP or Parasolid file and import it to Shapr. This technology is called direct modeling.
Sketches are fundamental in Shapr. You can use your Apple Pencil to draw Sketches on the grid and on planar faces. Then, using constraints, you can set up measurements and relationships between them. Constraints are an extremely powerful way of creating accurate sketches, without having to do labor-intensive manual calculations. You can use your sketches and closed sketches to create all kind of bodies: bodies of Revolution, Sweeps, Lofts, etc.
The powerful sketch engine of Shapr makes a lot of tools you use in Rhino unnecessary.
Basic interaction and tools
In Shapr a lot of your modeling can be done without using a menu or pressing a button - simply by using the Apple Pencil. However, Shapr also provides a lot of tools (similar to Rhino commands), including boolean operations, lofts, sweeps, transformations and much more.
The file formats supported by Shapr will allow you to seamlessly integrate it into your existing workflow. You can export and import STEP, IGES, X_T (Parasolid), and STL files (only export), the industry standard file formats. If you are transferring data between Rhino and Shapr, you should always prefer the STEP file format. Shapr likes accurate solid models, so it's worth considering to set the precision settings of Rhino to the most accurate values that your modeling process allows.
When you are exporting a solid model from Rhino, be sure, that all the faces are joined, otherwise some modeling operations might fail in Shapr. However, you can also import non-solid bodies polysurfaces, surfaces, or 3d curves from Rhino to Shapr, and use them in all kind of modeling operations, like lofting or sweeping.
CPlane - construction planes:
Shapr - just like any other CAD system - supports Construction geometry, but not only construction planes (CPlanes) but also construction lines and points. You can create a construction plane in Shapr using the “Plane” button in the “Add” menu.
Commands - tools:
In Rhino, you can access all kind of modifiers using commands. In Shapr these tools are accessible under the Tools menu.
Copy & Paste:
To copy and paste a body, sketch, or face, use any of the Transform tools and turn on “Copy”. The transformed shape will be copied.
Shapr can be an incredibly useful extension for your existing workflow built on Rhino, and it can completely replace some or all of your other modeling tools. As a next step, you may want to watch some of the introductory tutorials in our Design School, following this link.
