Autodesk Revit 2020 delivers several new functionalities. One that stands out from the rest was created for the structural engineer. Steel Connections for Dynamo and its sample scripts will help engineers to work more productively when modelling, placing steel connections, optimizing design and material consumption.



AutodeskRevit 2020提供了多种新功能。从结构工程师那里创造出一个与众不同的产品。Revit平台上的可视化编程工具Dynamo及其脚本的钢结构连接功能将帮助结构工程师在建模、放置钢结构连接件、优化设计和计算材料消耗时更高效地工作。





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的用户可以基于在名为Autodesk Steel Connection 2020的新软件包下分组的新Dynamo节点，创建用于在结构或其选定部分上添加钢结构连接件的规则。这些节点可以识别用于放置标准和自定义连接并启用简单的规则流。从先前选择的模型元素开始，这些元素被分组为潜在的连接节点。它们根据某些标准进行过滤（可能与截面，倾斜角度，倾斜角度，元素轴之间的角度和区域类型有关）。最后，放置钢结构连接件。



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.



在所有这些开始听起来太技术性的内容之前，我们要重点指出可以通过使用Dynamo播放器、从Revit里面来控制规则，其中可以调整主要参数，以便根据需要放置钢结构连接件。随Dynamo软件包提供的开箱即用脚本的集合里面拥有两种工具，可立即用于在钢结构建筑物中放置各种连接类型，以及根据每个项目的要求，为定制工作流程构建模块。



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.



民主化自动化流程在定义我们的使命中发挥了关键作用，这就是为什么我们认为规则需要由您最熟悉的环境中的任何结构工程师控制。这就是我们鼓励Dynamo专家在实施自定义标准化规则时，通过基于开放式规则的系统在自己的公司中建立连接。



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.



想象一下这个新工具的所有好处：通过减少创建钢连接所需的手动操作数量，提高生产率，优化更多，并提高建模质量。此外，通过在项目的早期阶段提供可用于冲突检查的详细模型，您将受益于与架构和MEP的改进协调。



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.



在结束之前，重要的是要提到另一个旨在提高钢连接建模生产率的功能 -标准钢连接传播。这提供了一种简单快捷的方式来放置标准连接，方法是在模型中的任何位置自动传播它，并找到相同的上下文。为了获得更多控制和更广泛的适用性，可以使用Steel Connections for Dynamo根据可配置的规则在标准的选定部分中放置标准和自定义连接，并允许各种过滤标准。

光铭研究院评：Autodesk赌对了dynamo这条路，自动化程度大幅度提高，理论上dy二次开发高手可以写出来一个钢结构设计软件了，软件公司与用户生态圈一起开发，好像是CAD+lisp时代的翻版。dynamo=autolisp。当然，这说的还都是国外设计院，他们有专门的BIM经理帮助设计师做这种开发工作（以前就是CAD经理的干活），国内没有。
