　　摘要：Revit平臺中創建扶壁模型包含繪制扶壁輪廓和路徑、放樣、陣列復制、計算旋轉角度并逐一偏轉等操作，步驟繁雜且耗時;若是采用以往開發的插件創建扶壁式擋土墻模型則導線的類型和擋土墻的方向受到限制。為了滿足多樣化的扶壁放置需求，簡化扶壁放置操作步驟，可利用Revit開放的二次開發接口API和C#語言技術，基于Visual Studio開發平臺，模擬扶壁建模和放置的過程以程序代替結構創建、放樣、陣列復制、偏轉等操作步驟，并將復雜導線類型和擋土墻方向納入程序判斷，編寫扶壁放置程序，通過參數化界面調整各項操作，使其具有直觀性和靈活性，從而高效便捷的對各類擋土墻完成扶壁放置操作。

　　Abstract: Creating counterforts model in the platform of Revit includes drawing counterforts contour and path, lofting, copying array, calculating rotation angle and deflecting one by one, which is complicated and time-consuming. If using the previously developed plug-ins, the wire type and the direction of the retaining wall are limited. In order to meet the diversified requirements and simplify the operation steps of counterfort placement, the open secondary development interface API of Revit and C # language technology can be used to simulate the process of counterfort modeling and placement based on Visual Studio development platform, and the operation steps of structure creation, lofting, array replication and deflection can be replaced by programs. The complex wire type and retaining wall direction are included in the program judgment to complete counterfort placement program. The placement operation of counterfort is adjusted through the parametric interface to make the program intuitive and flexible, so as to efficiently and conveniently complete the counterfort placement operation for all kinds of retaining walls.
