- [Topology (3D Modeling)](https://help.maxon.net/zbr/en-us/Content/html/user-guide/3d-modeling/topology/topology.html.md): Topology is the term used for the pattern of polygons that make up a mesh. People talk about "good topology" when a mesh is well made for a particular …

However, with …
  - [Spirals](https://help.maxon.net/zbr/en-us/Content/html/user-guide/3d-modeling/topology/zremesher/spirals/spirals.html.md): Because ZRemesher is an automatic algorithm, it can in some cases produce a topology without edge loops in places with tubular shapes such as legs, arms …

  - [Partial Mesh (ZRemesher)](https://help.maxon.net/zbr/en-us/Content/html/user-guide/3d-modeling/topology/zremesher/partial-mesh/partial-mesh.html.md): ZRemesher has the ability to retopologize only the visible portion of a partially hid­den model. In this case ZRemesher will automatically maintain …
  - [Symmetry (ZRemesher)](https://help.maxon.net/zbr/en-us/Content/html/user-guide/3d-modeling/topology/zremesher/symmetry/symmetry.html.md): ZRemesher can evaluate your model’s volume and create its topology symmetrically, even if the original topology is not symmetrical — such as when using …
  - [Using Curves](https://help.maxon.net/zbr/en-us/Content/html/user-guide/3d-modeling/topology/zremesher/using-curves/using-curves.html.md): The topology produced by ZRemesher tries to respect your model’s shape as much as possible. However, no program can have the same understanding of your …
  - [High Polycounts](https://help.maxon.net/zbr/en-us/Content/html/user-guide/3d-modeling/topology/zremesher/high-polycounts/high-polycounts.html.md): ZRemesher is designed to create new topology over nearly any existing model. It can be a model with many subdivision levels, a scanned model of all …
  - [Transferring Detail](https://help.maxon.net/zbr/en-us/Content/html/user-guide/3d-modeling/topology/zremesher/transferring-detail/transferring-detail.html.md): There will be times that you wish to retopologize your model while keeping all the detail that has been sculpted on the model. There are two approaches to …
  - [Tips and Tricks (ZRemesher)](https://help.maxon.net/zbr/en-us/Content/html/user-guide/3d-modeling/topology/zremesher/tips-and-tricks/tips-and-tricks.html.md): Here are a number of Tips and Tricks to keep in mind when using ZRemesher:
  - [ZRemesher 4.0](https://help.maxon.net/zbr/en-us/Content/html/user-guide/3d-modeling/topology/zremesher/zremesher-4-0/zremesher-4-0.html.md): ZRemesher will recreate a new polygonal structure for your model, with a controlled flow of polygons and a global polycount value. In just a few seconds …
- [Topology Brush](https://help.maxon.net/zbr/en-us/Content/html/user-guide/3d-modeling/topology/topology-brush/topology-brush.html.md): On the left, the drawn curves with the polygons in preview mode. On the right, the new polygons with a predefined thickness, ready to be sculpted. Model …
- [Mesh Fusion](https://help.maxon.net/zbr/en-us/Content/html/user-guide/3d-modeling/topology/mesh-fusion/mesh-fusion.html.md): ZBrush is able to literally fuse different models together, creating clean topology to connect them. This Mesh Fusion operation will only affect the …
- Retopo
  - [Retopology](https://help.maxon.net/zbr/en-us/Content/html/user-guide/3d-modeling/topology/Retopo/01-retopo.html.md): The Retopo brush provides a comprehensive toolset for creating clean, animation-ready topology over your high-resolution sculpts. Unlike automated tools …
  - [Core Workflow: Creating Vertices](https://help.maxon.net/zbr/en-us/Content/html/user-guide/3d-modeling/topology/Retopo/02-core-workflow/02-core-workflow.html.md): The foundation of your retopology starts with placing individual vertices (points) on your model's surface. These vertices are the building blocks of your …
  - [Building Topology: Extruding and Merging Edges](https://help.maxon.net/zbr/en-us/Content/html/user-guide/3d-modeling/topology/Retopo/03-building-topology/03-building-topology.html.md): Once you have initial polygons, you can grow your mesh organically by extruding edges. Edge extrusion creates new polygons by extending existing edges …
  - [Working with Retopo Curves](https://help.maxon.net/zbr/en-us/Content/html/user-guide/3d-modeling/topology/Retopo/04-working-with-curves/04-working-with-curves.html.md): For faster topology creation over larger areas, you can draw curves that generate polygonal strips.
  - [Using Topology Patches](https://help.maxon.net/zbr/en-us/Content/html/user-guide/3d-modeling/topology/Retopo/05-using-topology-patches/05-using-topology-patches.html.md): The Retopo brush includes over 200 pre-made topology patches accessible through the IMM Viewer tabs at the top of the screen. These patches provide …
  - [Tips and Best Practices](https://help.maxon.net/zbr/en-us/Content/html/user-guide/3d-modeling/topology/Retopo/06-tips-best-practices/06-tips-best-practices.html.md): Start with major forms: Block out large areas first using curves or patches, then refine with individual vertex placement. This top-down approach is …

- [ZSphere Topology](https://help.maxon.net/zbr/en-us/Content/html/user-guide/3d-modeling/topology/zsphere-topology/zsphere-topology.html.md): Using ZSpheres, you can create new topology in ZBrush as well as shrink wrap that topology to your existing model.
  - [Appended ZSpheres](https://help.maxon.net/zbr/en-us/Content/html/user-guide/3d-modeling/topology/zsphere-topology/appended-zspheres/appended-zspheres.html.md): Most ZBrush users retopologize using binded ZSpheres (Tool:Rigging:Select Mesh.) Another method is to retopologize using appended ZSpheres. Appending …
