The algorithm used to calculate the volume or Is it me or is Revit just not very accurate with cut and fill? This guy has a real monotone boring voice and may put you to sleep….zzzzzzz Chris Fox discusses family types in this one. Follow along as Chris Fox teaches Revit from the beginning. One of the lessons from the Revit Essentials Tutorial Series available on DVD or Online. Revit Architecture 2009 In Place Families Whenever there is a change of basic dimensions there will always be a crossover period until all the stocks of the old profile have been sold and only the new profile as available.ĭue to the difference in profile the Section Properties for I and Z will be slightly different, and one should not be used instead of the other without checking with the Engineer.Ĭourse Overviews and Demo Lessons link to Ĭourse Outline - Printable pdf PDF documentĬhris Fox introduces the Revit Structure 2009 Tutorials, a 24 hour video series on DVD or streaming online fromĬhris Fox discusses designing wall structure with Autodesk Revit Structure 2009. Parallel Flange Channels were only introduced about five or six years ago, perhaps if your Local Engineer is a young chap who only knows the PFC and not it’s predecessor.Īccording to the 4th Impression of the Historical Structural Section Handbook printed in 1991 there has been changes to the dimensions of the Channel Section in 1904,1921,19 \Metric Library\Structural\Framing\Steel\Corus AdvanceĪnd you will find UKPFC-Parallel Flange Channelsīeing an old engineer I liked the old channels especially for use in external exposed locations as the rain and water would run off the sloping bottom flange. Take a peek just below the Corus Advance folder under Steel i.e. ![]() \Metric Library\Structural\Framing\Steel are Channels to BS4 Part1:1980 The Channel Sections your Engineer is specifying is based on the current Dimension and Properties from the Corus brochures and is based on a Parallel Flange Channel to BS4-1:2005. Have you come across this - or can you suggest why this should be - my local Engineer cannot see why they should be different.” 180 x 75 x 20 channel specified by Engineer, nearest in Revit is 178 x 76. While I find that most steel sizes quoted to me by Engineers are the same as the serial sizes and weights in the Revit families, the C channel sizes are always slightly different - e.g. ![]() I recently received the following question about UK serial sizes and materials not being included in Revit:. The families can be downloaded off the AUGI Revit Structure Families area from the thread where I have posted them for UK and European users to harvest them. So I opened the txt file in excel as a csv file and altered the units and dimensions to create a family based on UK Sawn Softwood Structural Timber Sizes to BS EN 336:2003 and those used in the TRADA Span Tables. It was in the process of drawing the timber joist layout when I found that there is not a UK Sawn Timber Family!
