3.2.1 Google Sketchup Our current preferred program for room modeling is Google Sketchup (SU). SU2Odeon is the ODEON plug-in for SU that allows you to make direct use of SU models in ODEON. SU is a 3D modelling software which is operated very intuitively. It is available in a free as well as a pro version and can be downloaded at: http://sketchup.google.com/. SU also allows you to create renderings of your rooms for impressive visualization. To learn using Google SketchUp it is a must to watch some of the introduction videos which are found at: http://sketchup.google.com/intl/en/training/videos.html. In a day or so you should have learned the basics. To make use of the SU models in ODEON, the SU2Odeon plug-in must be installed. It can be downloaded from http://www.Odeon.dk/Download. The download includes installation instructions and last minute instructions. Once you have installed SU and the plug-in SU2Odeon you can start creating models for ODEON using SU. Just save the SU model in the ODEON room folder and press the ODEON icon in SU menu bar then SU2ODEON will create a .par file which you can open directly in ODEON. (note that for large models the SU application may emit the message SketchUp is not responding while it is in fact still working on creating the .par file - normally it only takes a few seconds but in some extreme cases it may take hours). The models created in SketchUp and exported by SU2ODEON, are inherently compatible with the requirements set by ODEON; Plane surfaces No repeated points No surfaces without area Multi loop surfaces are converted into single loop surfaces Layer support Automatic explosion of blocks Unique surface numbers* *Surface properties assigned in ODEON (such as materials, surface sources, reflectors and grid surfaces) are preserved when the model is re-modeled in SU and re-exported for ODEON. In version 11 and later, the Google Sketchup file (.skp file) is automatically copied with an ODEON project when using the File|Copy files menu from within Odeon. 3-39
3.2.2 ODEON Extrusion Modeller A small modelling program; the ODEON Extrusion Modeller is included with ODEON. The program is found in the Windows start menu along with the ODEON program. It can also be launched from within the ODEON editor. The Extrusion modeller allows modelling so called extruded geometries in a graphic environment – or in other words to draw geometries using the mouse. An extruded surface is a flat 2D outline, drawn at a specified drawing depth (the third coordinate) and with an extrusion height. When assigning an extrusion height to the 2D outline, it becomes a holster outlined by the edges of the ‘extrusion surface’, if so desired this holster can have a bottom and a top. Z Odeon©1985-2004 X O Y Z In the extrusion modeller it is possible to make one drawing which contains multiple extrusion surfaces, each described by a 2D outline (a simple drawing) and the line properties; drawing depth, extrusion height, bottom check mark, top check mark and a name. If the extrusion is created in the XY- plane, then one extrusion surface may form a volume with walls and optional floor and ceiling, whereas other extrusion surfaces define tables, chairs or screens. Odeon©1985-2004 X O Y X Z O Y For some geometry it may be more appropriate to draw the geometries in one of the other main planes (XZ and YZ planes). As an example the auditorium.par model in the Figure has been modelled in the XZ plane, using separate extrusion surfaces for the room, the wall with windows holes, the table and the windows. Odeon©1985-2004 The Extrusion Modeller and file formats The output from the extrusion modeller comes in two formats; the extrusion model can be saved in its own native format in an .oes file. This file can be edited and extended at a later point in the extrusion modeller e.g. if wishing to change width of the auditorium above, to change some of the points in the drawing or to add other features. 3-40
