Surface mesh generation in [[EM.Cube]] is a two-step process. First, a tessellated version of an object in your project workspace is created. Then, the tessellated object undergoes a surface re-meshing to generate regularized triangular cells. This process is fairly straightforward in the case of flat planar structures. For curved surfaces and curved [[Solid Objects|solid objects]], the quality of the initial tessellation of the object is very important and directly affects the quality of the final surface mesh. You can access some additional mesh [[parameters]] by clicking the {{key|Tessellation Options}} button of the Mesh Settings dialog. In the Tessellation Options dialog, you can change '''Curvature Angle Tolerance''' expressed in degrees, which as a default value of 15°. This parameter can affect the shape of the mesh especially in the case of solid CAD objects. It determines the apex angle of the triangular cells of the primary tessellation mesh which is generated initially before cell regularization. Lower values of the angle tolerance result in a less smooth and more pointed mesh of curved surface like a sphere.
