    Creating Family-Precast Concrete

    Hi Everyone,

    This quiery is probaby suitable for structural gurus but anyone who is able to help would be of great assistance.
    I'm fairly new to this forum and would like some help in creating families for concrete structural products. I'm wondering if I could use all our 2D profile from autocad library and create families from them. The products are hollowcores, shell beams, double-Ts as well as other products. Any ideas and suggestion would be very much appreciated!
    Btw im new to Revit Structural as well having spent the last 10years with AutoCAD but our company are making the transition into Revit so i'm trying to get one step ahead if you know what i mean.

    Thanks

    Hi,
    In Revit can make any family. Let's make an example of the family based on your AutoCAD.

    Ah, the old Stresscrete Drawings...

    Easiest way that i have found to make 2d Revit Components, is:

    Import the CAD file into a fresh Revit Project
    explode the CAD Fully
    change the line-styles to what you want
    make sure the component is clean
    Copy-clip the individual component Lines into a fresh new Detail Component File
    Paste, & then save into your Library

    "Fresh Revit" can be either a family of project file

    Basically your Importing the CAD File into a Newly Created Revit File, so you can do some editing to it
    Once the Editing is done, you can copy the good stuff you need out of the said file, into other files, and finally delete the original said file
    that way you can preserve the integrity of your files.

    The true power of Revit is Realized when you create 3D components. (using the 2D profiles from Revit as an import, then extrude using the "Create Forms" commands, ie: Extrusion, Blend, Revolve, Sweep, Swept Blendm, Void Forms.) And then also Create 2D Components that Dwane states above. Then load the 2D Component into the 3D Component, and turn off the correct Visibility of the 3D in Plan, Section or Elevation based on the 2D that is loaded and place on the respective planes. Also match the Parameters with the 2D with the 3D, so that when you flex the component both move the same. This would allow you to have 1 component that you insert, and have more detail in Section or Elevation or Detail mode where you can also Keynote it. this is how I like to create Families and Components. It allows for less work when the team creates details, plus their is always the problem where details do not correspond to every instance of construction for a particualar project, and having the ability just to cut a section and see it correctly done and it is modeled in 3D and 2D and both correspond, where just having generic 2D details to try and get "Design Intent". I believe Design Intent is a flaw of the Design community, because we need to get it right the first time, having to do RFI's, ASI's, Addendum's and Change Orders is almost always because of "Design Intent" and the project not being vetted out correctly in 3D the first time.

    If you are talking about having your old profiles to use in creating new 3D components, I would suggest looking at the OOTB structural profile families, most of what you listed are already profiles in this folder. They might not be exactly what you are looking for but a good starting point. Also take a look at the OOTB detail item families if you are only looking for 2D information they might give you a good process on how to start.
