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.
