OASYS GSA 8.6 link to Revit Structure 2012

GSA Analysis is a highly intuitive tool from ARUP, enabling users to carry out 3-D linear, P-delta, non-linear static analysis, dynamic analysis and more. GSA 8.6 now links with Revit Structure 2012 enabling engineers to import models from Revit Structure 2012 to GSA 8.6. You can also import a GSA 8.6 model directly into Revit Structure; however, this will have some limitations.

I have set up a simple test which is shown below. GSA took through the Grids, Levels and all structural objects. Below you can see the model in Revit Structue 2012.

Here is the same model transferred to GSA 8.6. Note that the transfer should be made from the Add ins tab in Revit Structure.

Understanding Concrete Beam Joins

A few weeks back I was asked how Revit Structure handles concrete beam joins and how to control and manage how beams are connected and processed at the junctions. In older releases of Revit the beams would always mitre which was good in some cases but in other situations really didn’t give the correct solution. I have now modelled the various configurations and created some images so you can see how the beams will join. If you do want a mitred junction which is not 90 degrees then you will need to use a precast material.

Revit Structure 2012 Command and Shortcut List

During training sessions I am often asked by delegates if there is a list of shortcuts available for Revit Structure. I have now put together a list of commands, Icons and shortcuts that I am making available to you as a PDF download, click the blue link to download (you lucky lot!!). It is a really useful document to assist you when working with Revit Structure or simply as a learning aid. I have included 394 commands from Revit Structure but not included the Ribbon mode commands.

Creating Structural Opening families for Walls

After a number of requests I have put together a quick tutorial on creating structural openings in walls using  customised door and window families. YouTube link below:

http://www.youtube.com/watch?v=4CC-bFFL8-M

 In many of the Revit Structure training manuals, a structural opening is often placed using the Wall Opening tool on the Home-Opening Panel as shown below.

This will produce an opening but will not automatically detail this in an elevation and section view with a symbolic opening symbol. I also find this type of opening a little difficult to control within the model once it is placed. An alternative to this method is to create wall openings using Doors and Windows. These tools are found on the Architect and Site Ribbon as shown below.

The door and window tools will create a basic structural openings through a wall and create the symbolic details required. Doors and Windows can be placed in plan views or sections and elevations if required. I often find a window opening very useful for creating high level openings for services by using the sill height tool in the properties window.

The main disadvantage with Door and Window openings is that the Width and Height parameters are Type driven which means that you will need to create a duplicate type for each new size which can get rather time consuming.

An alternative to this is to convert the type parameters to instance parameters within the family file. This will then create a nice and easy tool for structural Wall openings. See the youTube tutorial.

Service Openings through Beams

In a post a few months back I outlined a quicker way of producing openings in beams using a customised framing family within Revit Structure 2011. see link https://revitstructureblog.wordpress.com/2010/08/05/openings-through-beams-in-revit-structure/

Link you YouTube Tutorial:

I was asked the same question again last week and thought I would revisit the problem using some of the new Revit Structure 2012 features. I created a new line based family and made a void sweep with three instance parameters for the Length, Width and fillet Radius and then set the steelwork to ‘cut with voids when loaded’. This worked a treat and is a much quicker, more controllable way of creating openings in steelwork.

If any of you would like a YouTube video tutorial on how to create this family then let me know!

Setting Correct Structural Levels

 This may be a simple post and many of you may already be aware of the following but I am going to post it anyway! When modelling in Revit you will have a tendency to start at Level 0 but will later receive the correct or revised levels and need to change the levels. There is a simple way of achieving this rather than trying to move the entire structure, you can simply change the elevation base to shared.

In the above image you can see that the base level is set to 0.00m. To change this to the new required level, click the Manage ribbon and choose Coordinates – Specify Coordinates at Point. Click the Level you want to specify and then you can enter the correct level.

Nothing will change until you change the type properties of the Level and any Spot Levels you have on the model. Select a level and then choose type properties. You will need to change the Elevation Base from Project to Shared. This will then update all the levels within your project. You will need to also do this for your spot levels.

Hope this helps,

eTransmit for Revit Structure 2012

eTransmit has been around for the past 10 years in AutoCAD and it is now available for Revit 2012 on Autodesk Labs as a technology preview:

http://labs.autodesk.com/utilities/revit_etransmit/

With eTransmit for Revit, you can:

  • Copy and detach a Revit model and associated files to a single folder for internet transmission. This removes the typical error messages when you copy central files using the operating system.
  • Locate dependent files automatically and include them in the transmittal folder, reducing the possibility of error. All dependent files are automatically converted to use relative paths to ensure that the dependent files can be located by the model.
  • Choose to include related dependent files such as linked Revit models, CAD files, DWF markups, decal images, and external keynote files. You can transmit any Revit (.rvt) model that has been upgraded to Revit Release 2012.
  • Transmit models that are using file-based worksharing or server-based worksharing. eTransmit for Revit will also work with non-workshared Revit models.

Common uses for eTransmit

  • Internal archiving
  • Sending deliverables to clients
  • Model exchange between consultants/partners
  • Model cleanup
  • Sharing models between disciplines
