In Ifc2x3 data exchange, only a primitive model is required as the vast majority of implementations are developed with the use case of coordination in mind.   If a shape representation isn't an extrusion, then commonly it's meshed into faceted faces with 3 or 4 edges.  I'd really like to see revolutions used more commonly as the impact on many file sizes would be dramatic. But a faceted brep can have any number of edges, and nominate internal bounds for openings. Refer to this image and this description.  We've been recently working pretty hard on ensuring that we can g ..read more

I've been supporting some client and project workflows with an emphasis on translating Bentley AECOSIM models into Revit, particularly for some of the big Infrastructure projects under development and construction in Australia. It's taken some time, and some trial and error approaches.  But the process now is really encouraging, and I'm seeking more users and test cases to try this approach.  Note that the development is being undertaken as "Just In Time", so that I'm not promising that it's perfect yet.  But I can say that if you try this approach and find issues, if you can s ..read more

Shape to Fabrication 2016 is on next week, and I'm really excited about returning to London to attend and present at this event.  There's an amazing line up of speakers and the opportunity to speak with the McNeel staff attending makes this an event not to be missed.  Thanks to Simply Rhino for all the effort to organize this. It's 7 years ago that I last attended Shape To Fabrication, number 3 at Metropolitan Works in 2009.  I'd been promoting and publicly releasing the Rhino plugin online that I'd been working on in house at Expedition,  known as  SSI (Smart St ..read more

It's great to announce that Mac users can now start using the Geometry Gym plugins in Grasshopper. At this point in time to access Grasshopper, you need to be running Rhino for Mac WIP, then Grasshopper can be accessed from rhino command ExplicitHistory (the original plugin name from many years ago). You can download the Geometry Gym installer from http://www.geometrygym.com/downloads At the moment I've compiled the Bullant and ggRhinoIFC addons, others can be built on demand (noting that many use windows applications programming interfaces that won't work on mac). Here's a script to t ..read more

Rhinoforyou will be exhibiting Rhino3d and Grasshopper3d as a BIM tool at the BIM World 2016 in Paris on 6th and 7th April (stand 124).  Rhinoforyou will demonstrate (and answer questions) about BIM workflows with Rhino v5 and Grasshopper using 3rd party developments by Geometry Gym and VisualARQ amongst others ..read more

A few years back, I advanced on a Grasshopper plugin to generate SCIA Engineer structural analysis data.  For a few different reasons, this stalled and didn't work as successfully as I would have liked. Late last year I started work again on the ability to convert Structural Analysis IFC files into SCIA, and now I've enabled the same code into a revived Grasshopper plugin. It's now available from http://www.geometrygym.com/downloads  At present it can generate beam elements with releases, restraints etc.  I will be looking to enable loads, area elements and other features that ..read more

The core c# classes developed by Geometry Gym to import and construct IFC (Industry Foundation Classes) have been released as an Open Source project under the MIT license. The source code is being hosted on GitHub, https://github.com/jmirtsch/GeometryGymIFC I've uploaded the compiled dll to https://www.nuget.org/packages/GeometryGymIFC/ Note this isn't the entire IFC code base that Geometry Gym has developed, the interfaces to Grasshopper, Revit, Rhino, Navisworks, Tekla and the various structural analysis software remain closed source (for at least the time being) as the reve ..read more

It's a historic day, I've added a RhinoMac download area to the website, http://www.geometrygym.com/downloads I believe these are the first plugins developed for RhinoMac, and it's an exciting new era. Initially the two plugins available are BullAnt, and ggRhinoIFC (to import and export IFC files). You need to install the WIP (Work in Progress) build of RhinoMac, you can download from here: http://www.rhino3d.com/download/rhino-for-mac/5B/wip Commands will then be available starting with gg (no toolbars yet).  You can open/import IFC files from the file menu.  You can run rh ..read more
