AutoCAD Structural Detailing – Steel Fabrication Drawings Tutorial

Link to YouTube Video:

Many of you have probably had a dabble with AutoCAD Structural Detailing and placed a few 3D connections on a steel structure using the automated macros and not really taken it any further! The process of creating fabrication drawings is surprisingly fast and efficient providing you have a good set of templates and a basic understanding of the workflow.

In this tutorial I thought I would share the process of going from a 3D ASD model to finished fabrication drawings. We will be looking at the following features:

  • Element Positioning – The process of assigning unique marks to each object.
  • Grouping – Organising objects into assemblies
  • Using Templates
  • Creating Printouts

Revit Structure Slab to AutoCAD Structural Detailing 2012


Link to YouTube Tutorial:

The current workflow to reinforce structural elements from Revit to AutoCAD Structural Detailing is currently limited to ‘standard’ objects such as beams, columns etc via the Revit Structure extensions. You may be interested in a process that I have discovered to take any object modelled in Revit Structure and then create the required formwork drawings in AutoCAD Structural Detailing and then add the reinforcement. I have used Revit Structure to model a slab but you could use any solid modelling software to produce your required geometry. Below you can see the drafting view imported into Revit Structure from ASD.

I have started in Revit Structure by creating a slab and then adding a slab edge and an in-place model of a thickening.

I can then save this as an ACIS solid and then import this into ASD (see the YouTube video for details). You will need to Union all of the solids to create a composite model. Type in UNI on the command line and select all the geometry. One this is done you can then select the Use 3D solids command in ASD.

 This will then produce the required formwork in ASD and I can proceed to reinforce the slab and take the drawing back into Revit Structure by linking the 2D drawing into a drafting view. This means that if you update the reinforcement in ASD the drafting view will also update in Revit Structure.

AutoCAD Structural Detailing Reinforced Concrete Tutorial

In this short tutorial I will take you through some of the AutoCAD Structural Detailing (ASD) basic tools for reinforcing a beam. You will see how to create the bar and ranges and also how to schedule and create drawing views. There is a lot to learn with this package and it is packed with features so you will need a template that creates the correct standard as well as your company’s preferred graphical standards.

Remember that ASD is included with the Revit Structure Suite and many of you will probably have this installed on your desktop but possibly configured to run as vanilla AutoCAD.

You can see below that in the Job Preferences you can set your design preference and drawing preference. The good thing here is that the data is all editable and you can edit the maximum bar lengths and limit larger diameter bars to shorter lengths to have pity on the fixers!

You will then need to create the various styles for the graphical appearance of your tags and dimensions and also determine how ASD represents ranges.

You will also see a concrete beam transferred from Revit Structure to ASD which will fully detail all the formwork and create the element and views ready for you to add bar!

Hope this helps,


Section mapping from AutoCAD Structural Detailing to Revit Structure

A quick Tip and Trick when working with Steel models between ASD and Revit Structure.

 When transferring a steel model from Revit Structure to ASD (AutoCAD Structural Detailing) your standard sections will be mapped without any problems. However, if you need to create any bespoke sections then you will need to generate these first in ASD and then the sections will appear in the Revit Structure content generator.

In the above example, you can see the custom sections shown in the Revit Content Generator (Found on the Extensions Ribbon).

Here is the same profile in ASD.

Revit Structure 2012 to AutoCAD Structural Detailing Tutorial


As promised I am going to take you through the process of connecting a steel model created within Revit Structure 2012 to AutoCAD Structural Detailing 2012 (ASD) and generate some fabrication details that we can link back into Revit Structure utilising a drafting view.


ASD is a very comprehensive application that can generate fabrication drawings for steel detailers and also generate drawings and schedules for reinforced concrete. In this tutorial we will focus in on the steel fabrication. This can be really useful for providing typical connection details within your Revit Structure projects and is certainly quicker than creating the various 2D details within Revit, especially when more than one view is required.

I wanted to keep the tutorial fairly ‘snappy’ ,being restricted to just 15 minutes in YouTube, so have limited this to the basics but as with any complex design tool, templates rule! You will need to invest some time to get a good set of templates together for ASD and get the various dimension and annotation settings configured. This can be a very daunting task, see a typical dialog box below! mmm

However, once this is done, the production of fabrication drawings and CNC code becomes very quick and easy. Also it is worth noting that ASD contains quite a few links to ROBOT Structural analysis. Note that this will also import an engineer’s model from ROBOT which can be quite handy.

I hope that this has given you a basic introduction to the features and techniques needed to transfer models from Revit Structure to ASD.


Revit Structure to ASD Steel Detailing

 With the new extension tools you can now pass your steel frame directly from Revit Structure to Autodesk structural detailing providing you have the extensions installed. This is a great way of providing typical connection details both in 2D and 3D within Revit Structure. You first create the steel frame in Revit Structure and then pass this to ASD (AutoCAD Structural Detailing) via the extensions link.

If anyone is interested in a full tutorial on the workflow in Revit Structure and ASD then let me know and I will produce a YouTube tutorial on this subject?

This will then pass the steelwork to ASD, you can either directly launch ASD or create a DWG file to load later if ASD is not installed on your machine. It is then a simple case of creating the various steel connections via the numerous macros that exist within ASD. Each connection is broken down into component parts and will require positioning ( unique part numbers). This is done by selecting all the parts and selecting Auto Positioning. You can then create automatic drawings from the parts and ASD then creates separate sheets with all the required fabrication drawings. These can then be directly linked in to Revit Structure via a drafting view. This is a great way of providing structural connections to prospective fabricators without having to draft them manually.

Revit Structure 2012 Extensions

Many of us have eagerly awaited news and the release date of the Revit Structure 2012 extensions from Autodesk. I have now installed these tools and thought I would quickly post some of the new and improved features. Here is a list of the new and updated features:

  • Floor Vibrations Analyzer (New Feature)
  • Gravity Column Designer (New Feature)
  • Ribbon Integration (See above Image)
  • Column Reinforcement
  • Beam Reinforcement
  • Content Generator
  • Reinforcement Extensions
  • Rebar Interferences Extension
  • CIS/2 Import Extension
  • Steel Connections

There are too many improvements to these tools for one post so I will review each new and improved feature in the coming weeks. If you want to install the Revit Structure 2012 extensions then download them from the Autodesk Subscription site.
