Hi,

We've got some fully detailed models of steel framing in Inventor Pro.  We've seen on You Tube that it can go into Robot. 

Question is what comes into Robot, and how well does it work?

Inventor - Robot Integration

The extension for the data exchange between Inventor and Robot can be activated from both programs. Depending on the activation context, the dialog can look slightly different:

1. The Inventor - Robot Integration is activated from Inventor.

The module is activated from the Inventor program by pressing the Export button available when the Simulation is active in the Autodesk Inventor Frame Analysis module.

The Integration with the RSA program dialog contains the following functionalities:

-      Send Simulation to Autodesk Robot Structural Analysis (direct transfer) - creates calculation model directly in Robot on the base of the current Simulation in the FA module. The option is not available if the Robot is not installed.

-      Save Simulation as Autodesk Robot Structural Analysis RTD file (indirect transfer) - opens the standard dialog for file saving. Robot does not have to be installed on the computer.

Additionally, you can define a method of creating the model in case of the direct transfer:

-      Create new Autodesk Robot Structural Analysis project

-      Merge with the current Autodesk Robot Structural Analysis project - modifies the currently opened project in Robot after the changes made in the FA module.

These options are not available for the indirect transfer (using the RTD file).

2. The Inventor - Robot Integration is activated from Robot.

The module is activated from the program, from the Add-inns menu with the use of the Inventor - Robot Integration option.

General information

The link between the Autodesk Inventor- Frame Analysis and the Autodesk Robot Structural Analysis programs allows for mechanical simulation and design of the steel frame structure.

The Autodesk Inventor program is used to design 3D mechanical models and to create design documentation. The program contains the Autodesk Inventor Frame Generator module which allows to model steel frames for mechanical devices. The Autodesk Inventor Frame Analysis (FA) allows further simulation of the frame structure. Once the support conditions and loads are defined, the structure behavior analysis can be carried out. As a result, the structure displacement, the internal forces and the stresses can be obtained.

Autodesk Robot Structural Analysis (Robot) is a structural analysis and design software application. It is capable of analyzing virtually any type and shape of a structure as well as designing elements of this structure (steel, RC, timber elements).

The module for the Autodesk Inventor Frame Analysis - Robot integration allows you to perform:

-      Static and modal analysis of the frame:

The results are presented in the FA module.

The structure analysis in the FA module is based on the Robot internal analysis kernel.

-      Export of the structure model to the Robot program or saving data in the Robot (RTD) program file format.

It is possible to carry out further analysis of the structure after transferring the structure model to the Robot program. Robot will perform the following types of analysis:

• linear
• steel, concrete, and timber design to many codes
• dynamic and seismic analysis, including time history
• non linear analysis, geometrical and material
• buckling.

The data exchange is unilateral. The model saved in the RTD file is updated after it is changed in the FA module. Modifications made in Robot cannot be sent to the FA module.

The static model considers the following attributes of the member elements within the scope offered by the Autodesk Inventor Frame Analysis module:

-      profile section defined from the standard steel section database which are available in the Autodesk Inventor Frame Analysis. If the corresponding section is found in the steel section databases available in Robot, all of its properties come from this database. In any other case the section is defined without considering its shape. The values such as the section areas, the moments of inertia etc. are assigned from the Autodesk Inventor Frame Analysis database.

-      members’ ends releases, i.e. pinned or fixed connections of the members

-      structure support conditions

-      rigid links which allow to create rigid membrane between the members’ nodes

-      loads.

Hi Artur,

Further to the thread above in relation the Inventor-Robot link can I ask; if shell/plate elements modelled on Inverntor can be transferred to Robot.

You have mentioned above that steel frame can be transfered to Robot. But I would like to know about how we can transfer shell/plate elements from inerntor to robot; it may be just a geometry and we may need to assign properties in Robot. I am looking to transfer a Cylindrical steel stack supported on 3D Steel frame from Inverntor to Robot for structural analysis only. I have not tried the Inverntor-Robot-Integration yet as the Stack invernor model is with our client. I would like to know more about this integration before I request a inventor model for Structural analysis. What I am told by our client is that they have a very big file in Inventor where they have created parts of the stack in "Vault" and assembled together. As you can understand the inventor model created by mechanical team(our client) also contains non structural elements like insualtion.

What I am looking here is something like creation of Structural model based on Architectural model.

Thank you,

Hi Artur,

Thank you for your quick response. Is there any other way to transfer a structural model containing plate/shell elements from Inverntor to Robot. May by "Save As" from Inventor in a specific file format?

Thank you,

[Artur.Kosakowski]

Try to save it as dxf and then open it in Robot.

Thank you. Is tehre any anyother better format than dxf?

[Artur.Kosakowski]

What is exactly the object that you want to transfer to Robot? A solid, meshed shell? Could you attach its screen capture?

Hi Artur,

I would like to tranfer the plates. I have used dxf before in some other application it only brings geometry and, there will be many lines to work. Attached is a screen print from "Design review 2013". The height of the stack section shown on the screen print is about 35m. It extends above to 85m in total

I want to know what would be the best way to tranfer model from Inventor to Robot fory this type of elements.

Thank you.

[Artur.Kosakowski]

If you have the silo meshed (as surfaces) and you are able to save it as dxf and then explode the object into set of 3D faces then they can be imported to Robot as surface elements which you can convert into panels.

You may also try to use *.sat format. Mind that you should mark the indicated option in Robot and restart the program before opening the sat file from Inventor.

Mind to switch it off again and restart Robot for a new "standard" project in Robot.
