Dynamo for Revit users can create rules for adding steel connections on a structure or a selected part of it, based on new Dynamo nodes that are grouped under a new package called Autodesk Steel Connection 2020. These nodes can identify similar geometrical conditions for placing standard and custom connections and enable a simple flow of rules. Starting from previously selected model elements, these are grouped into potential connection nodes. They are filtered on certain criteria (which can be related to section, slope angle, slant angle, angle between the axes of the elements, and zone type). Finally, the connections are placed.

Dynamo for Revit的用戶可以基於在名為Autodesk Steel Connection 2020的新軟體包下分組的新Dynamo節點，創建用於在結構或其選定部分上添加鋼結構連接件的規則。這些節點可以識別用於放置標準和自定義連接並啟用簡單的規則流。從先前選擇的模型元素開始，這些元素被分組為潛在的連接節點。它們根據某些標準進行過濾（可能與截面，傾斜角度，傾斜角度，元素軸之間的角度和區域類型有關）。最後，放置鋼結構連接件。

But before all of this starts to sound too technical, it』s important to point out that the rules can be controlled from Revit by using the Dynamo player where the main parameters can be tweaked so that connections are placed as needed. The collection of out-of-the box scripts that are delivered with the Dynamo package represent both tools for immediate use of placing various connections types in steel buildings and building blocks for bespoke workflows, depending on the requirements of each project.

在所有這些開始聽起來太技術性的內容之前，我們要重點指出可以通過使用Dynamo播放器、從Revit裡面來控制規則，其中可以調整主要參數，以便根據需要放置鋼結構連接件。隨Dynamo軟體包提供的開箱即用腳本的集合裡面擁有兩種工具，可立即用於在鋼結構建築物中放置各種連接類型，以及根據每個項目的要求，為定製工作流程構建模塊。

Democratizing automated processes played a key role in defining our mission and that is why we believe rules need to be controllable by any structural engineer from within the environment that you are most familiar with. And this is what we encourage Dynamo experts to pursue when implementing customized standardization of rules for placing connections by an open rules-based system in their own companies.

民主化自動化流程在定義我們的使命中發揮了關鍵作用，這就是為什麼我們認為規則需要由您最熟悉的環境中的任何結構工程師控制。這就是我們鼓勵Dynamo專家在實施自定義標準化規則時，通過基於開放式規則的系統在自己的公司中建立連接。

Imagine all the benefits of this new tool: increased productivity, greater optimization, and improved quality of modelling by reducing the number of manual operations needed for creating steel connections. In addition, you』ll benefit from improved coordination with architecture and MEP by having a detailed model available for clash checks in the early phases of the project.

想像一下這個新工具的所有好處：通過減少創建鋼連接所需的手動操作數量，提高生產率，優化更多，並提高建模質量。此外，通過在項目的早期階段提供可用於衝突檢查的詳細模型，您將受益於與架構和MEP的改進協調。

Before concluding, it is important to make a reference to another feature aimed at enhancing the modelling productivity for steel connections – Standard steel connections propagation. This delivers an easy and fast way to place a standard connection by propagating it automatically everywhere in the model where an identical context is found. To have more control and a wider range of applicability, the Steel Connections for Dynamo can be used to place standard and custom connections in the selected part of a model based on rules that are configurable and allow for various filtering criteria.

在結束之前，重要的是要提到另一個旨在提高鋼連接建模生產率的功能 -標準鋼連接傳播。這提供了一種簡單快捷的方式來放置標準連接，方法是在模型中的任何位置自動傳播它，並找到相同的上下文。為了獲得更多控制和更廣泛的適用性，可以使用Steel Connections for Dynamo根據可配置的規則在標準的選定部分中放置標準和自定義連接，並允許各種過濾標準。

光銘研究院評：Autodesk賭對了dynamo這條路，自動化程度大幅度提高，理論上dy二次開發高手可以寫出來一個鋼結構設計軟體了，軟體公司與用戶生態圈一起開發，好像是CAD+lisp時代的翻版。dynamo=autolisp。當然，這說的還都是國外設計院，他們有專門的BIM經理幫助設計師做這種開發工作（以前就是CAD經理的幹活），國內沒有。
