1. What is AutoCAD Structural Detailing?

AutoCAD Structural Detailing software is a solution for detailing and creation of

fabrication shop drawings for steel and reinforced concrete structures.

Use the Steel module to leverage building information models from Revit Structure

software, import CIS/2 files, or create models, enabling fast and efficient generation of

steel connections and shop drawings.

Dedicated Reinforcement module automates reinforcement definition and shop drawing

generation for all types of structural concrete members. Improve overall accuracy with

AutoCAD Structural Detailing through material-specific bills of quantities and schedules.

AutoCAD Structural Detailing significantly reduces drafting time by automating time-

consuming, redundant tasks. Typical structural and elemental connections are

generated using intelligent tools, while schedules and material takeoffs are automatically

created to increase your productivity and reduce errors.

The Object Inspector tool provides easier access to structural elements, generates

drawings, and enhances your project.

AutoCAD Structural Detailing is only available in AutoCAD Revit Structure Suite 2009

which includes AutoCAD 2009 + Revit Structure 2009 + AutoCAD Structural Detailing

2009.

2. AutoCAD Structural Detailing STEEL Module

The Steel module is a tool for generation complete fabrication workshop documentation -

drawings and bill of materials.

The process of creating drawings in ASD Steel is automatic.

Drawings are generated basing on a 3D structure model. Model is prepared using both

options available in ASD Steel and pure AutoCAD program. In case when a structure

model is modified, it is possible to update the automatically created documentation.

3. Workflow

The work in AutoCAD Structural Detailing software may be divided into the following

stages:

MODELING - defining or importing 3D model of structure (CIS/2 format or direct

link to Autodesk Robot Structural Analysis 2009 software)

POSITIONING - assigning names to structure elements

DRAWING GENERATION - manual or fully automatic generation of workshop and

assembly drawings

4. Configuration: Preferences & Templates

The first step to start working with AutoCAD Structural Detailing is selecting a template.

The template is a file with initial, predefined settings of the working parameters.

Template is a set of many parameters characteristic for ASD2009: tolerances, families,material databases, profile databases, ASD styles (table styles, dimensioning styles,

description styles), project information, initial parameters of dialog boxes, document

templates and connectors settings.

All of these parameters can be changed and adjusted to users preferences. The

settings are grouped together and are available from Menu Bar or directly from General

Toolbar as Project Preferences.

5a. Modeling - Profiles

Depending on needs/regional requirements we can create profiles by means of a widerange of available section databases from all around a world. There are over 50databases available in the program.

In Profile dialog box we select type of profile choosing it from the active databases

automatically loaded by the template.

Next we define profile Material and Family (beam, column, profile etc).

To complete profile definition we should specify offsets and rotation regarding to

insertion point. It is possible by typing required values or by graphical selection ofcharacteristic points of the section.

After that we can insert defined profile using one of three available methods (by 2 points,

by line or by point)

User-defined section shapes Compound profiles and castellated beams

5b. Modeling Connections

When a steel structure model is complete, we can start defining connections between

particular elements.

In many cases connection consists of many subparts (profiles and plates) and its

definition is really laborious and time-consuming.

In ASD we can prepare connections quickly and easily using special macros that

automate the whole process. After that we can copy the defined connection for other,

similar profiles or create connection template to use it later without necessity of setting

all parameters again.

Miscellaneous types of connections

5c. Modeling Parametric Structures

The next stage of automation of 3D model definition is a group of macros that enable

generation of typical parts of steel structure (e.g. different types of roof trusses, stairs

and staircases, railings, ladders) or automatic elements placing (such as grates or

purlins).

After definition of necessary parameters, creation of complete part of the structure (e.g.

whole staircase) lasts a few minutes instead of a few hours.

Another great advantage of using macros is an easy way to change parameters of the

generated objects. Laborious and time-consuming repetitive drafting tasks concerning

changes of many associated elements are reduced to simply correction of necessary

parameters and generation of this part of structure once again.

6. Integration with Revit Structure and Autodesk Robot Structural Analysis

The whole process of structural project creation (from concept to fabrication) can be

divided into three stages - definition of structure model, structural analysis and

preparation of workshop documentation.

ASD software supports the engineer in the last stage of this process. Program allows

the user to create the structure model using ASD modeling features, but it is also

possible to use ready model defined during the previous stages of the design process.

We can use model of steel structure created in Revit Structure and exported to CIS/2

format (*.stp file) or simply import *.rtd file from analysis software Autodesk Robot

Structural Analysis.

Having completed geometry of the steel structure we can finish modeling by adding

necessary details (connections, ribs, plates and stairs or railings). After that we can start

generating drawing documentation. Thanks to the integration the whole process of

creation workshop documentation is faster.

7. AutoCAD Structural Detailing Reinforcement Module

AutoCAD Structural Detailing software enables the automatic definition of reinforcement and

generation of shop drawings for all types of structural concrete elements.

The Reinforcement module offers templates that comply with detailing practices of many

countries, ensuring automatic adherence to local detailing methods and appropriate bar

schedules. Fast and efficient detailing and scheduling of concrete elements, including

spread footings, stairs, beams, columns etc. can be executed through intelligent tools and

macros.

8. Configuration: Preferences & Templates

Job preferences and templates are two most important places where all default/initial

program settings are included.

In Job preferences you may define:

- work units,- standards

- databases of bars and wire fabrics

- parameters of bars and wire fabrics presentation, etc.

The template includes the settings relating to any type of style:

- dimension lines

- reinforcement description

- summary tables

- colors, layers, names, fonts, etc

All templates can be found in the following location: c:\Program Files\Autodesk\AutoCAD

Structural Detailing 2009\Cfg\

The names of the templates for reinforcement module start from RBCR-0XX.dwt name.

XX is a numerical notation specific for a given country.

9. Rebar Definition

The basic and the most frequently used method of reinforcement definition is manual

insertion of reinforcing bars.

Immediately after reinforcement definition the program automatically calculates

reinforcement length and automatically creates the reinforcement description.

Then, after using reinforcement distribution command the distributions are made.

The total amount of bars is calculated basing on the reinforcement distribution.

The program includes the advanced mechanism of creating any type of distributions, thus

providing ergonomics and efficiency of drawing generation. The special attention should be

paid to freedom and unlimited possibility of shaping the reinforcement. Thanks to possibility

of changing the polyline to bar it is possible to obtain any shape of reinforcement.

This option is especially helpful when drawing reinforcement for engineering objects such as

bridges, industrial structures

Definition of the reinforcement shape basing on the polyline

10. Macros

Macros are the next method of reinforcement definition.

Thanks to using the macros we may quickly obtain the complete reinforcement drawing of

typical elements of RC structures.

The typical macros are:

- beam

- column

- spread and sleeve footing

- stairs

- pile cap- ground beam and many others

11. Integration with Revit Structure and Autodesk Robot Structural Analysis

The last method of obtaining reinforcement is making use of integration of the ASD program

with Revit Structure and Autodesk Robot Structural Analysis.

Thanks to using the Autodesk Robot Structural Analysis program we obtain completely

calculated and dimensioned reinforcement, thanks to using connection with ASD we obtain

the automatically generated drawings of the calculated elements.

In case of the Revit Structure program we may create 3D reinforcement for the elements

such as: beams, columns, foundations, etc. by means of the appropriate Extension and then

using the Extension for drawing generation we may automatically generate the drawings of

these elements in AutoCAD Structural Detailing.

12.Material Takeoffs

One of the most interesting program features is the mechanism for generation of

reinforcement tables.

This is one of the most important components ofdrawing documentation and thats why the

program has been equipped with the advanced mechanism that makes it possible to adjust

the style of the table to the individual requirements of the customer.

By means ofReinforcement tables style managerthe User may compose his own style of

the table.

The tables may be created using graphic selection of reinforcement, by defining the range ofreinforcement positions or for the whole project. There are detailed tables in the program

both for bars and wire fabrics.


14/14

The additional possibility is creating the table in the external file of MS Office application

(Word & Excel) or inserting the table directly in the drawing.

The tables are created automatically and in case of reinforcement modification they are

updated on demand without necessity of verification and taking control over the introduced

changes.
