Rhino files can be massive, containing massive amounts of geometry (surfaces, curves, and meshes). You may have heard of the “usual suspects,” but you might be wondering if there is a way to reduce their size. The good news is that there is.
SurfacesWithinSolid
Rhino users often complain that their files are too large, but they don’t know why. Rhino uses special display meshes to display surface objects, and a large number of polygons can lead to a large file size. The good news is that there are several methods to reduce file size.
One of these is SurfacesWithinSolid extraction. This feature helps reduce file size without sacrificing quality. By separating face and edge meshes, the SurfacesWithinSolid command will reduce the number of mesh faces. It will also maintain the quality of the model and minimize texture and geometry distortion.
NonManifoldFaces
Using the NonManifoldFaces command in Rhino can help you reduce file size while maintaining the quality of your model. It reduces the number of face triangles in your model without affecting the geometry or texture. To minimize the size of the file, you should make your model as simple as possible.
This command can be used to reduce the number of polygon faces in a surface model. All you need is a mesh object with a specified quality. If you don’t have a mesh object, you can also use the MeshToNURB command to turn a simple object into a polysurface. You can then apply the MergeAllFaces command to make your model simpler.
When using non-manifold faces in Rhino, you need to define your alignment point. This point can be an object’s location or the overall bounding box. In this way, the mesh will be seamless. In addition, you can specify the normals manually or let the software do the work for you.
_-SaveAs
One of the most important considerations for a mesh is file size, and there are several ways to achieve this while working in Rhino. Extraction of mesh faces is a great way to minimize file size while maintaining quality. The ReduceMesh command reduces the number of mesh faces while retaining geometry and texture information. The result is a triangular mesh that is much smaller. Alternatively, you can choose to separate faces from edges by selecting the NonManifoldFaces option in the MeshSettings menu.
The _-SaveAs command is also a useful tool for reducing file size. The command is not auto-completed and must be entered in the command line. It removes all bitmaps from the document, including objects.

Extraction of mesh faces is an important part of creating a 3D model, and in Rhino, there are several ways to do this. One method is to use the ReduceMesh command, which will reduce the number of mesh faces while preserving quality and minimizing texture and geometry distortion. The ReduceMesh command can also be used to separate edges and faces. This option can be found in the GVol MeshSettings menu.
Another way to reduce file size in Rhino is to use blocks. Files containing massive geometry can be very large, so it’s a good idea to use blocks to reduce their size.

Rhino files often contain a massive amount of geometry, such as curves, surfaces, and meshes. Because of this, users may not be aware of what causes a large file. One of the main culprits is the very fine display mesh settings of surface objects, which can create a large file.
When extracting mesh faces in Rhino, it is possible to reduce the file size by using the ReduceMesh command. This command helps reduce the number of mesh faces while preserving the quality and minimizing geometry distortion. Generally, this results in a triangular mesh. Other options include SurfacesWithinSolid, which extracts surface meshes from solids. In addition, NonManifoldFaces separates edges and faces. You can also use the IniErrorCheck option from the GVol MeshSettings menu.
