The perimeter points are typically defined using the MPt statement. The syntax of ElevSurf2 is: ElevSurf2 The ElevSurf2 only differs from ElevSurf in that a top and bottom surface may be specified (the T/B/N option). A unique number from 1 to 2.147.483647 for identification of the first surface in the ElevSurf2 surface. Using the same number, but with negative sign, define the surfaces and their counter parts mirrored in the XZ-plane (Y = 0). First point number in the floor perimeter. The floor points are typically MPt statement. See example below. The number of surfaces to be created by the ElevSurf2 statement. If creating a cylinder a number between 16 and 24 is suggested (if it’s a column only use six to eight surfaces). Height is oriented in the Z-direction. The T/B/N parameter specifies whether the ElevSurf2 should have a top and /or a bottom. The options are T, B, TB and N (for none). If Top or bottom may only be included if all of the points in the floor in the elevation surface are in the same plane. Example on use of the MPt and ElevSurf2 statements. First the perimeter points (point 1 to 23) at the floor level of an office environment is described using the MPt statement. Then the elevation surface is created from these points, creating the perimeter walls of the office with a constant height of 2.7 metres. In this example the X-coordinates are made in absolute values whereas the Y-coordinates in most cases are in- or de-creased using the =+ or =- options To create a closed ElevSurf2 (that is, the first wall joins the last wall) first and last point in the series of points handled to the ElevSurf2 must be identical - in this example, point 1 and point 23 are identical. App-26
If an elevation surface has 22 surfaces then 23 points must be made available to the ElevSurf2 as in this example. ### MPt 1 23 0 0 0 = 7.48 = 2.3 = = = =-2.38 = 8.35 = = = =-1.26 = 10.76 = = = =+4.64 = 64.78 = = = =-2.68 = 51.52 = = 49.62 =-2.02 = 48.22 =+1.1 = 45.3 =-2.68 = 43.85 =+1.45 = 42.40 = = 40.98 =-1.45 = = 0 = 34.5 = = = =2.1 = 30.13 = = = =-2.13 = 0 0 0 ElevSurf2 1 1 22 2.7 TB walls ### Defining a number of surfaces using the CountSurf statement The CountSurf is mostly here for backwards compatibility. In most cases it will be easier to use the Surf statement along with a for….end loop. A Counter surface is divided on two lines and must follow the syntax: CountSurf A unique number from 1 to 2.147.483647 for identification of the surface. Using the same number, but with negative sign defines the surface and its counterpart mirrored in the XZplane (Y = 0). A CountSurf will take up several surfaces numbers, which must all be unique. The number of surfaces to be created by the CountSurf call. Optional user defined name for easy identification of the surface, e.g. ‘Beam'. Each surface may be bounded by between 3 and 50 corners, which all lie in a plane. Corner numbers refer to the corners, which must have been defined (e.g. using the Pt or CountPt statement) before using the surface statement. The order of listing must be as obtained by travelling around the surface's edge (in either direction). The list of corners must be on the same line. A room may contain up to 10000 surfaces. Example: CountSurf 1000 5 Beam in ceiling 1000 1100 1200 1300 App-27
