Advance Design and Revit Workflow

 

Geometric data and FEM results can be transferred from Advance Design to Revit® in order to take advantage of industry-driven intelligent automation.

On this page, we will describe how you can connect Autodesk Revit® Structure with Advance Design in order to apply either of the following connected workflows:

 

BIM Workflow

BIM Workflows

Workflow ‘A’ is described below, as this covers both scenarios.

Once you have the descriptive and the analytical models properly defined in Revit®, you are ready to export your project to Advance Design.

Note

You need to have BIM Connect installed on your machine, either the single tool or as part of the GRAITEC PowerPack for Revit®.

In order to cover a complex workflow, we will start with a Revit® model having the analytical model defined.

Open the model which contains geometrical description of the elements and activate the Analytical Model view from the project browser in order to visualize the analytical model:

Once you have the descriptive and the analytical models properly defined in Revit, you are ready to export the project to Advance Design

With the GRAITEC PowerPack for Revit®, you have a dedicated ribbon with numerous tools and functions, including BIM Connect:

Clicking the BIM Connect icon will access several options to manage the workflow:

BIM Connect commands

To check the options and set your preferences when exporting project models click Settings:

Export settings

Transfer settings

The Settings dialog has four sections:

Concrete section mapping options

Concrete section mapping

Make sure the option Export only elements with analytical model is checked.

SYNCHRONIZATION: Ensure both Import FEM results for * options are checked to receive FEM results.

Next, activate the Export command by clicking export option in BIM connect. The following dialog and options appear before applying the export:

Graitec Export Tools

Graitec Export Tools

- GRAITEC  BIM  -  Exports  a  GTCx  file  which  is  an advanced BIM format developed by GRAITEC;

- Other formats - Select export format from drop list;

- Country library – Select country section to set the library used in the GRAITEC Software (useful for the mapping process).

- Automatic software launch Advance Design

When a new material is detected, BIM Connect will prompt asking if you want to update the mapping database in real time. Just select Create new material mapping:

Material mapping

Material mapping

If you have selected the option Automatic software launch, you will arrive directly in Advance Design with a 3D model corresponding to the analytical model transferred from Revit® and the project tree structure intact.

3D model transferred in Advance Design

If you have NOT selected the previous option, it means that the BIM Connect prompted to create an exchange file on disk which you have to import manually in Advance Design:

  1. Run Advance Design and create a new empty project.

  2. From the Advance Design BIM tab on the Ribbon, select the command Import GRAITEC BIM.

If an unknown material or section is detected, you will get a dialog prompting either to map with an existing material\section from the Advance Design library or to create a new entry using the Revit® properties:

Assign a material

At this stage of the workflow, you have a 3D model in Advance Design which corresponds exactly to the analytical model sent from Revit®, including the geometry, the loads, the analytical supports and the systems description in Advance Design corresponding to the levels description in Revit®:

Note

The self-weight of the elements was not defined and therefore not transferred from Revit® to Advance Design. Please ensure you select the dead loads case in Advance Design and activate the self-weight in the right axis.

Self-weight options

You can access all the properties of each member, either to check what was defined in the Revit® analytical model, or to stipulate your own assumptions. This is an important step for you to be able to trust the FEM model.

You can define what kind of finite element you would like to apply, e.g.; a beam with 6 degrees of freedom, a truss with only 3 degrees of freedom working in tension or compression, a tie, a cable, etc.

You can check and change the boundary conditions on the elements; rigid or semi-rigid links, elastic supports, articulations between slabs and walls, etc.

You can set the meshing parameters.

You can define any missing loads, either manually or using the automatic generator for climatic and seismic loads:

Advance Design functionalities

With Advance Design, you can run a FEM analysis and get all the requested results (including internal forces on all elements for all the load cases) that you can post process graphically or with tables in reports:

Post processing in Advance Design

Once the calculation is complete, we need to ensure we export the FEM results to Revit® in order to automatically fill the analysis results database (called “results package” in Revit®).

First, make sure that the option Exports forces > On linear elements on nodes is activated in the Application option dialog from the Manage tab:

Export options

 

Then, from the analysis model in Advance Design, go to the BIM tab and activate the Export option from GRAITEC BIM panel:

Export option

This action will save a GRAITEC BIM (GTCx) file this on disk which describes both the complete geometry of the 3D Advance Design model and also includes the complete FEM results.
