1 Precast Concrete Industry Extensions for Autodesk Revit Structure 2012 Reinhard Lackner IDAT SE4030 This class shows how extensions to Revit Structure can dramatically speed up creation of precast elements. You will learn how to create reinforcement for precast elements by simply choosing a reinforcement type. You will learn how to make connections between columns and beams with corbels or other elements and how to connect columns with column shoes to the foundations. We will cover assemblies and describe how you can find same precast elements automatically. The class also covers how to use the Split tools in Revit Structure to split walls into single parts, convert them to assemblies, and create shop drawings for them. Anyone who is involved in the precast industry will benefit from this class. Learning Objectives At the end of this class, you will be able to: Automatically create shop drawings Automatically create precast elements and use assemblies and the split tools in Revit Structure Connect columns and beams with corbels, and connect columns with column shoes to foundations Create reinforcement for precast elements About the Speaker Reinhard is from Austria and studied computer science at the Technical University Vienna. He has been the general manager for the company IDAT ( since His technical know-how is in the precast industry. lackner@idat.de

2 1. Introduction What are the Revit Precast Tools? The Revit Precast Tools are Extensions to and around Revit to support the workflow from design to fabrication for the Precast Concrete Industry. These tools are developed by the company IDAT ( in cooperation with Autodesk. Who is IDAT? IDAT is a German based company developing software for the Building Industry since The main product is a full developed software solution for the Precast Concrete Industry based on AutoCAD Architecture. This software is used by clients in over 30 countries world wide. Revit Precast Tools for Autodesk Revit Structure The Revit Precast Tools are currently under development. A version with some restrictions is ready for download from the IDAT website: Actual functionality of the Revit Precast Tools Creation of connections Creation of reinforcement Wall segmentation Converting to assemblies with equality check Creation of shop drawings Exporting data to machine files Exporting data to external database 2

3 Workflow of the Revit Precast Solution: The workflow of the Revit Precast Solution from design to the fabrication is the following: Ribbon Tab of the Revit Precast Tools After installation of the Revit Precast Tools there is a new ribbon tab inside of Revit available: Preconditions All families should have Precast Concrete as structural material to work properly and profit from Revit functions. 3

4 Creation of connections for structural elements Connecting beams to columns with corbels Select one or more beams and call the command Corbel: On each place where a beam touches a column on the correct height a corbel will be crated in the column. 4

5 Connecting beams to columns with joist hangers Select one or more beams and call the command Joist hanger: On each place where a beam touches a column a joist hanger will be crated in the column and in the beam. Assemblies After creating corbels, joist hangers or later even reinforcement for a selected object the Revit Precast Tools creates automatically an assembly and add the original and the new created objects to this assembly. The system will automatically detect if the assemblies are the same. 5

6 Connecting columns to foundations with column shoes Select one or more columns and call the command Column shoe: On each place where a column sits on top of a foundation 4 column shoes will be crated in the column and 4 bolts in the foundation. 6

7 Creation of reinforcement Reinforcement for corbels Select one or more corbels and call the command Corbel reinforcement: For each selected corbel reinforcement will be created. 7

8 Reinforcement for foundations Select one or more foundations and call the command Foundation reinforcement: For each selected foundation reinforcement will be created. Reinforcement for columns Select one or more columns and call the command Column reinforcement: For each selected column reinforcement will be created. 8

9 Combining columns and foundations with a special reinforcement Select one or more columns and the foundations together and call the command Column reinforcement: For each selected column and foundation a special reinforcement will be created in a way that the column and the foundation can be produced in the precast factory as one part. The column, the foundation and the created reinforcement will be assigned to one assembly. Reinforcement for beams Select one or more beams and call the command Beam reinforcement: For each selected beam reinforcement will be created. 9

10 Wall commands Reinforcement for wall openings Select one or more wall openings and call the command Opening reinforcement: For each selected opening reinforcement around the openings will be created. On each side of the opening there will be two bars with a predefined overlapping created. Wall segmentation Select one or more walls and call the command Segmentation: Each selected wall will be converted to a part. After that each part is checked if the weight and the length meet the requirements of the precast factory and the working site (e.g. crane). If not, the part will be divided into several parts until they fulfil the requirements. At the end each part, the reinforcement and the mounting parts which are inside of the part are added together to an assembly. A wall assembly is a ready to produce precast wall element. 10

11 Parts During the segmentation the walls are divided with parts. This dividing can be edited by selecting a part object and calling the Edit Division command from Revit: After that the dividing lines are visible and they can be changed: Wall reinforcement Select one or more wall assemblies and call the command Wall reinforcement: Each selected wall assembly will be reinforced with predefined bars on the in- and outside of the wall. 11

12 Creating shop drawings Select one or more assemblies (column, beam, foundation or wall) and call the command Shop drawings: For each selected assembly a shop drawing with views will be created. These shop drawings can be seen in the project browser of Revit under Assemblies. 12

13 Creating data for external programs Data for external database Call the command Database: The data for all assemblies in the project will be written in an external database. This contains the geometry data, all the mounting parts and the reinforcement. Lists can be created out of this data or they can be exported to other programs like ERP systems. 13

14 Machine files for the Stacker program Select one or more wall assemblies and call the command UNITECHNIK: For each selected wall assembly a UNITECHNIK file will be created. The UNITECHNIK file format is a well know format in the Precast Concrete Industry. With this file all the needed information like the geometry, the concrete, the mounting parts and the reinforcement are transferred to the factory for an automated production. This file can also be used to define the transport stacks with the Stacker program: 14

15 Production planning with the Palletizer program The Stacker program exports the stacking information with the UNITECHNIK file to the Palletizer program. With this program the planning of the production tables or the production lines can be done: The Palletizer program exports the UNITECHNIK files finally to the master computer in the precast factory which feeds the data to the machines (e.g. plotter, shuttering robot, bar bending and cutting machine, concrete spreader ) Change to the model If there is a change in the Revit model after all the machine files are created only the UNITECHNIK files for the according assemblies must be created again. 15

16 Summary: The Revit Precast Tools supports the Precast Concrete Industry in the following areas: Creation of connections Creation of reinforcement Wall segmentation and parts Converting to assemblies with equality check Creation of shop drawings Exporting data to external programs Changes in the model Production The Revit Precast Tools supports and speeds up the full workflow from design to fabrication for Precast Elements inside of Revit The Revit Precast Tools can be downloaded: 16
