Subdivision modeling is a technique used in 3D modeling to create organic shapes with smooth surfaces. Rhino 3D CAD is a popular software for subdivision modeling, and while it has many benefits, it also has some drawbacks. Here are some pros and cons of subdivision modeling using Rhino 3D CAD:
Pros:
Creates smooth and organic shapes: Subdivision modeling allows you to create complex and organic shapes with smooth surfaces that are difficult to achieve with traditional modeling techniques.
Easy to learn: Rhino 3D CAD is a user-friendly software that is easy to learn and use, even for beginners.
Fast and efficient workflow: Subdivision modeling in Rhino 3D CAD allows you to quickly create and modify your models, saving you time and increasing your efficiency.
Flexible and versatile: Rhino 3D CAD offers a wide range of tools and features that allow you to create a variety of models, from simple to complex.
Cons:
Limited precision: Subdivision modeling in Rhino 3D CAD can be imprecise, making it difficult to achieve exact measurements and dimensions.
Steep learning curve for advanced features: While Rhino 3D CAD is easy to learn for basic features, it can be challenging to master more advanced features, such as creating complex surface networks.
Limited control over geometry: With subdivision modeling, you have limited control over the geometry of your model, which can make it difficult to achieve specific shapes and structures.
This video also talks about Symmetry modelling. Symmetry modeling in subdivision 3D modeling is the technique of creating a model with a symmetrical design, where one half of the model is mirrored to create the other half. This technique is often used in character modeling, vehicle design, and other types of 3D modeling where symmetry is important.
To create a symmetrical model in subdivision 3D modeling, the model is typically created as a single half, with the center line serving as the axis of symmetry. The half is then duplicated, mirrored, and merged with the original to create the full model.
Generally, the benefit of using symmetry modeling is that it can save time and effort when creating models that require a high level of symmetry, as only one half of the model needs to be created manually.
Subdivision modeling is a popular technique used in 3D modeling to create smooth and curved surfaces from simpler geometry. Both Rhino and Blender support subdivision modeling, but they have some differences in the way they implement it.
In Rhino, SubD is a relatively new feature that was introduced in Rhino 7. SubD stands for Subdivision Surface, which is a type of NURBS geometry that can be subdivided into smaller faces to create smooth surfaces. Rhino's SubD modeling allows for precise control over the shape of the model, with the ability to adjust the density of the mesh, and to use creasing and softening to control the sharpness of edges. Rhino's SubD modeling can be used to create highly precise and accurate models, making it popular in industries such as product design and engineering.
Blender, on the other hand, has a more robust set of subdivision modeling tools that allow for more organic and fluid shapes. Blender's subdivision modeling allows for the creation of highly detailed and complex models, including characters and creatures, and it supports a range of different subdivision algorithms, including Catmull-Clark and Loop.
In summary, while both Rhino and Blender support subdivision modeling, they have different strengths and are often used for different types of modeling tasks. Rhino's SubD modeling is known for its precision and accuracy, while Blender's subdivision modeling is known for its ability to create organic and complex shapes.
This is great! Please do more sub-d tutorials on rhino, these are really helpful, thanks a lot!
Nicely organized video. I would like to see more subD videos with more advanced topics
Seus vídeos me ajudaram bastante. Saudações aqui do Brasil.
Thanks for viewing :)
Hello! Thanks for your great tutorials, you are really helping me model my product design assignments! I am having a problem right now. I have two SubD objects that I created using mesh. Now I'm trying to do boolean difference on them but for some reason when I click mesh boolean difference or normal boolean difference, the program won't allow me to choose these subD objects. Is it possible for you to help me?
what if we have done the shape nicely in subd, then we need to put another design/pattern on it? it will broke the topology of the primary subd and change the shape due the pattern applied has complicated shape. hope u understand what im saying. hard to say without visual.
Sorry for the late reply. Yes, once an operation such as solid boolean difference etc is applied...the topology is broken...because the SubD is now converted to polysurface.
