2. MODELING

CHAPTER 2 "MODELLING" 60 This one is a random warped contour in space. With the calculation of the surface the corresponding grid is created. The process behind this command is that the program, upon inserting the points, automatically creates the contour with lines which are automatically placed in a new layer called "Plate 3D Line". OBSERVATION: To avoid errors, when defining an outer boundary with points on the surface finite elements, and when there is already a boundary with lines, the program does not allow a second boundary to be created. 4.2.4 Holes Command to specify contour contours of contingent Points on the grid surface. Call the command and define the outline of the hole, as for the outer boundary, using a "line" or "polyline". Then you select the command and point, with a left click, to one of the lines of the hole outline. Right click to complete. Using the "Calculate" command, which will be explained below, the surface grid is recalculated based on the hole as well.
