概述
世界著名結構工程軟體space gass是在Windows下的一個軟體，非常適用於在2D和3D下進行結構分析和設計。軟體包含豐富的型材庫，有Aust250、Aust300、AustAlum、AustOld、Austimb、Brish、ChinaGB、Duragal、Euro、Euro2、ILB、JapMet、Lysaght、SA、SA-BS、Smorgon、US等。為澳大利亞綜合技術軟體控股有限公司（Integrated Technical Software Pty Ltd）研發。現已推出第十版本。
Space gass的功能
基本功能
· 建模。能在2D和3D模式下進行結構建模。可以採用建模嚮導進行快速建模或者簡筆勾出結構，再對其截面進行定義。
· 分析。在對結構進行荷載布置後可以進行結構分析。有線性分析、非線性分析、動態分析和屈曲分析等。
· 互動功能。space gass可以和很多軟體進行數據互動。和CAD、BIM (building information management)可進行廣泛互動。其他軟體如CIMSteel/2 (CIS/2)或 IFC 等檔案也可以連線到 SPACE GASS. 包括STAAD, Risa-3D, SAP2000 ETABS, ROBOT, SmartPlant4D Structural 等等。軟體可以輸入輸出DXF 或SDNF檔案，但可能只有一些基本圖樣而缺少數據。正式版中用戶還可以將模型與Xsteel，Prosteel等軟體的模型進行互動使用。
·出報報告單。可以創建多種報告單，如材料單或者結構分析的表單，這些表單只需Windows有記事本即可打開。
Space gass基本繪圖與編輯命令
1.點擊繪圖按鈕來進行繪圖，或者點擊建模嚮導，填入正確數據即可快速建模。可以在結構中點擊構件或者接到進行編輯，拖動、刪除、移動或者複製。和CAD一樣，選框從左至右則選中所包含構件或節點，從右至左則為交叉選擇，所以與選框交匯的構件或者節點都會選中。
