2. MODELING

CHAPTER 2 "MODELLING" 45 4.2.1.1 Mesh with more mesh surfaces When we want to model meshes with common edges, we create a mesh with more mesh surfaces, so that the nodes on the edges, which will be created by calculating the matrix surface, will be created in the mesh. Model, are common to both surfaces. EXAMPLE: Draw on the desktop, using a line or polyline, two boundary surfaces, as in the example. With the command " Modeling ">>" 3D Surface ">>" Mesh ", you define the mesh group. Select from the " Surface 3D " group the command " External Boundary" and with left button select one by one the lines of the first surface (1st subgroup) and right button to complete. The dialog box that appears is for the specific subgroup and its characteristics. The check next to Flatness indicates that the surface belongs to the layer.
