Description

用于BIM管综深化设计的同模型多人协同作业方法 技术领域
本发明涉及BIM深化设计领域，尤其涉及一种用于BIM管综深化设计的同模型多人协同作业方法。
背景技术
建筑信息化模型(BIM)的英文全称是Building Information Model，是一个完备的信息模型，能够将工程项目在全生命周期中各个不同阶段的工程信息、过程和资源集成在一个模型中，方便的被工程各参与方使用。随着建筑信息化的高度发展,建筑信息模型(BIM)也在建设项目各方得到了广泛的推广与应用。
BIM众多应用之中，目前以revit平台的BIM管道综合(之后简称管综)深化设计最为成熟。将结构、水、暖、电模型全部整合到一个共享的建筑模型空间中，结构与暖通、电气与给排水管线间的空间关系三维可视化，工程师们利用三维剖切框，任意剖切模型查看的方式，在高仿真的三维模型中准确地寻找最佳的高程控制、空间共享及最合理的线路空间分配、安排，并最终整合成一个最优化的综合设计方案。
但上述应用，存在着以下不足：绝大部分建设工程项目，暖通、电气、给排水管道及其设备主要集中于地下室，因此BIM管综深化设计主要工作量在于地下室工程，而地下室工程又是整个工程最早开始施工位置。因此，项目开工后，留给地下室BIM管综深化设计的时间往往非常紧迫，很多时候只能提交一个完成度不高的初步优化模型，对BIM技术的推广应用形成了阻碍。
当前BIM管综深化设计工作流程主要分为两步：第一步，各BIM工程师按结构、水、暖、电分专业多人同时建模，占据总时间约1/5；第二步，将所有专业模型整合后，由一人进行管综优化，剩下几人无法提供帮助，占据总时间约4/5，显而易见，第二步管综优化占据了绝大部分的工作时间。
目前市场上的协同作业软件只能实现不同作业人员分专业协同工作，而管综优化阶段必须整合所有专业模型，单专业作业无法在管综优化阶段工作；或将模型按楼层分割(一般分地上、地下)，再分配给2人协同作业，但是占据主要工作量的地下室模型仍旧无法实现同模型多人协同优化，提升效率有限，且按楼层分割模型并各自优化后容易导致竖向管道构件上下层错位，整合阶段需要二次返工调整。
基于此，本案由此而生。
发明内容
本发明的目的在于提供一种用于BIM管综深化设计的同模型多人协同作业方法，从软件技术和管理方法两方面共同实现，以此来缩短BIM管综深化设计的时间，提高效率，解决BIM推广应用的一大难题。
为了实现上述目的，本发明的技术方案如下：
一种用于BIM管综深化设计的同模型多人协同作业方法，包括以下步骤：
S1.利用BIM软件将各专业的BIM模型整合为一个BIM综合模型；
S2.将BIM综合模型划分为多个区域，并利用虚拟墙体对BIM综合模型进行分区，为各分区指定BIM深化设计师；
S3.利用BIM软件的二次开发功能，创建多个自定义三维视图，每个三维视图可创建一个独立三维剖切框，并将多个三维视图、三维剖切框指定分配给步骤S2中的BIM深化设计师；
S4.多个BIM深化设计师根据各自分配的作业分区、三维视图和三维剖切框，基于BIM软件平台，同时开展深化设计工作。
进一步的，在深化设计工作开展过程中，若存在跨越多个分区的大型构件，可通过相应几个分区的BIM深化设计师协商确定该构件优化方案。
进一步的，所述步骤S1中，将BIM综合模型按轴线或降板标高不同划分为多个区域。
本发明的优点在于：多个BIM深化设计师根据各自分配的作业分区和三维视图，同时开展深化设计工作，成倍的提高了BIM管综优化阶段的工作效率。
附图说明

图2为图1中BIM综合模型的俯视示意图；
图3为实施例中创建多个三维视图的软件界面示意图；
图4为实施例中用户A对BIM综合模型进行深化设计的状态示意图；

图7为实施例中用户D对BIM综合模型进行深化设计的状态示意图。
具体实施方式
以下结合实施例对本发明作进一步详细描述。
BIM综合模型现阶段无法在协同平台真正做到同模型协同优化，根本问题有两个：1、同一模型内，任意专业模型构件都是唯一图元，只能允许唯一用户操作，当A用户首先 操作某一图元时，其余所有用户必须排队等待A用户操作完成后才能操作该图元；2、三维剖切框也被软件视作图元，而管综优化作业时，必须不停的操作三维剖切框，以实现模型任意位置剖切、放大缩小操作，当一个用户在使用三维剖切框剖切查看模型时，其余用户只能排队等候，这就是BIM模型无法协同优化的最根本原因。
本发明提出一种用于BIM管综深化设计的同模型多人协同作业方法，包括以下步骤：S1.在revit软件平台，将土建、暖通、电气、给排水BIM模型整合为一个BIM综合模型。
S2.如图1和2所示，将整合后的BIM综合模型划分成多个区域，并以虚拟墙体分割模型，并为各分区分别指定BIM深化设计师，此步骤用于解决问题1。
本实施例中，BIM综合模型可按轴线或降板标高不同划分为多个区域，按降板分区的优势为：同一降板区域管线的基础标高是一致的，便于后续对管线的优化；按轴线分区的优势为：可以比较明确的划分所有梁板柱归属的问题，尽量避免出现同一梁或板，出现在两个分区(建筑的梁柱板一般情况下都是按轴线来定位的)。当然，该划分方式也可按伸缩缝、沉降缝或后浇带进行划分，效果与轴线划分类似。
将模型分区以虚拟墙体虚拟分割，并指定作业人员后，极大程度的避免了多人操作同一模型构件图元，只有极少数跨越多个分区的大型构件会出现同时操作排队的可能性，此时相应的深化设计师可通过协商解决(例如一根水管跨越了两个分区，相应两个深化设计师可协商讨论，得出对该水管标高、水平位置调整的共同方案)，避免以往模型按楼层实际分割后，上下层模型各自调整优化，后期模型整合阶段竖向管道构件错位问题。
S3.如图3至7所示，利用BIM软件的二次开发功能，创建多个自定义三维视图，每个三维视图可创建一个独立三维剖切框，并将多个三维视图、三维剖切框指定分配给步骤S2中的BIM深化设计师，此步骤用于解决问题2。经过研究后发现，所有专业模型构件和三维剖切框虽然同样被软件视作图元，但专业模型构件是任意状态的唯一图元，而三维剖切框是基于三维视图的唯一图元，所以只要能创建多个三维视图(如图3中的三维视图用户A、B、C、D)，并分别指定BIM深化设计师，那么该BIM深化设计师就能任意操作所分配三维视图下的三维剖切框，不受唯一图元排队困扰。虽然revit软件本身只具备一个三维视图，但revit支持二次开发，提供底层接口，可通过revit二次开发增加多个自定义三维视图(利用revit提供的二次开发底层接口进行三维视图的创建，属于现有技术，一般用于局部剖切出模型构件详图，而本实施例方案是在创建多个三维视图的过程中，发现三维剖切框是基于相应三维视图的唯一图元后，利用创建多个自定义三维视图的方法，来给多个BIM工程师分配独立作业的三维剖切框，以此来达成协同作业)。
S4.多个BIM深化设计师根据各自分配的作业分区、三维视图和三维剖切框，可实现在revit自身的协同平台或第三方协同平台，多人同时开展BIM模型管综优化设计工作，成倍的提高BIM管综优化阶段的工作效率。
上述实施例仅用于解释说明本发明的构思，而非对本发明权利保护的限定，凡利用此构思对本发明进行非实质性的改动，均应落入本发明的保护范围。
