Details: New Export Functionality: – Append “(Type)” to all internal Revit type property sets, to avoid having multiple property sets with the same name assigned to the same IFC entity. – Changed how the classification code is parsed so that classifications can have brackets and colons in them. – “Extra Low” level of detail now applies to all faceted BRep geometry, allowing many more files to export without hitting the size limit. – If a user–defined property set contains the same property name more than once, take the last non–empty value (don’t duplicate the property name). – Rebar elements can generate up to 1024 consistent GUIDs for individual IfcReinforcementBars, up from 256. – (IFC4) Zones can now have a long name, set by the “ZoneLongName” shared parameter for non–MEP zones, and the “IfcLongName” parameter for MEP zones.
Export Bug Fixes: – Don’t create orphaned IfcStyledItems. – Don’t export invisible geometry in beams. – Export DirectShapes of Walls category. – Export elements with empty custom classification field values. – Floors exported as IfcSlabs correctly report if they are load bearing or not, using either the “LoadBearing” shared parameter or the Structural built–in parameter, in that order. – Improve performance in certain cases where we can’t create a valid tessellation for a face. – The “Use active view to generate geometry” option now works correctly. – (IFC4) Correct the orientation of some IfcAdvancedBRep faces.
New Import Functionality: – Import IfcProxy as Generic Models.
Import Bug Fixes: – Fix how the IFC GUID is set for certain elements. – Fix the orientation of some imported objects where part of the local placement needs to be calculated. – (IFC4) Read in some missing relations caused by “IsDefinedBy” split into 3 inverse attributes.
In the first release, this node just uses Element Ids tobuild a long ‘or‘ search set, but this basic idea could easily be extended and adapted to more closely connect RevittoNavisworkssearch workflows through Dynamo.
As you are probably aware, when moving from Dynamo 0.9 to 0.9.1 you lose backward compatibility… in other words, you can’t open 0.9.1 files in 0.9 or earlier.
Before taking that step up to 0.9.1 and beyond, you may wish to apply a filename suffix to all of yourDYN files, so you are reminded of this issue when you open a DYN. I have a single folder with subfolders containing most of my DYN files, and I added the suffix (082) to all of them at once with this method:
Now, you basically have an inplace backup of files. When you open one of these dyns in 0.9.1 or newer, just remember that you should Save As in Dynamo, and then newly saved file will not be open-able in 0.9 or earlier.
At some point in the future you can then remove or upgrade all of these ‘older’ Dynamo files.
Archvision has a great reputation for providing quality Entourage RPC content and extensions to Revit, historically to assist you in creating more impressive presentation images and renderings. More recently, they have branched out to focus more on being a BIM content leader, including the development and release of their DETAIL WAREHOUSE app and content. This has been improved with recent updates, including the provision of DWG versions of this detail library.
A couple of months ago, Archvision partnered with AXYZ Design to now provide more high quality 3D people as part of the RPCs available to Archvision users (but purchased under a separate license). The official name of this product is “AXYZ Design 3D Human Characters Collections”.
For more information on the AXYZ partnership, DETAIL WAREHOUSE App Store release, and DWG availability, please see links, images and embedded press releases below.
Tekla has issued an XML file containing preset IFCsettingsforexport to Revit, specifically for Coordination. In some cases, this may already be available on your system, but in other regions you may have to install it manually.
Unzip the XML into this folder on all PC’s running Tekla Structures:
C:\TeklaStructures\*version*\Environments\australasia\system
Note: you may need to adjust the above path to suit your Region
Once this file is included in the folder mentioned above it will be available in all projects. When the user goes to File – Export – IFC they will have a pre-saved setting named “RevitCoordination”. The user simply Loads that setting and exports the parts needed.
This “RevitCoordination” setting also is setup to export additional property sets for Design Workflow data that is entered into the member properties (ie. Beam, Column etc.) in Tekla Structures.
