Revit 2016 Content

With every release of Revit I always use Beyond Compare to compare if/how the families vary from release to release.  This year in the US Imperial Folder (C:\ProgramData\Autodesk\RVT 2016\Libraries) I noticed that there is new organization along with new families for doors.  In 2015 there were 32 families and in 2016 there are 92 families, some of which are hardware families.  I haven’t had the chance to go through and look at these but a long overdue addition for all the architectural users who haven’t developed their own internal library yet.

For structure they have added the AISC 14.1 families that were a subscription bonus last year.  Along with this they have added a few structural tags to go along with some of the new features.

I was however disappointed that they didn’t add or change any of the tags that take advantage of the elevation of floors, roofs etc.

Curved Grid Quirk

There have been numerous posts on curved grid lines and getting them to display as well as many forum responses, even Tim’s post on correcting the height of the curved grids.   I have known about this for years but today none of these tools were working for me to display one single curved grid in a project, this is where I had noticed a quirk with grids.  I was able to reproduce this situation in both Revit 2015 and 2014, I don’t have older versions installed so couldn’t test there.

If the 3D extents of a grid line is larger than 237° the grid will not display in any perpendicular section.

Grid_CurveQuirk

If the grid needs to be shown further in plan and still needs to be displayed in sections, then toggling the grid extents to 2D and rotating it around in a plan view is the answer.  However remember this doesn’t have to be done in all the different plan vies, using “Propagate Extents” will push this change into all the other plan views as well.

 

Loaded Tags

Today I noticed a small feature that either I didn’t notice in the what’s new documentation, ok maybe I just missed it.  In Revit 2015 (currently using update 5) the Loaded Tags command has been replaced with the Loaded Tags and Symbols command.  It is nice to finally be able to set up what symbol will be used for those categories that use them, (i.e.: floor span direction, Structural Path Symbols, Structural Fabric Symbols).  This is documented in the Revit 2015 Help file.

Roof Cricket Family

This section of the handout will give step by step instructions to create a variation on the roof cricket family.

  1. Start with the OOTB GenericModelPatternBased template
  2. Draw a point directly on top of adaptive point 2, making sure the Z work plane is used as the workplane
    • Start the Reference Point command
    • Use the Set Work Plane command
    • Tab to get the horizontal work plane on point
    •  Roof_Cricket_Rig_01
  3. Select the recently placed point
    • In properties change the “Offset” value
    • Select the “Associate Family Parameter” button
    • Create a new parameter named “Rise”, and make it instance based
    •  Roof_Cricket_Rig_02
  4. Draw a reference line between the newly created point and adaptive point 4, making sure the Draw on Face selection is highlighted and 3D is checked in the options bar
    • Roof_Cricket_Rig_03
  5. Draw a reference line from adaptive point 1 to the new reference point
  6. Draw a reference line from adaptive point 3 to the new reference point
  7. Draw a reference line from adaptive point 2 to 4
  8. Set the work plane to be the horizontal plane of the diagonal reference line
  9. Place a dimension from adaptive point 2 to 4 (make sure adaptive points are being selected)
  10. Label the dimension with a new reporting parameter and call it “Run”
    • Roof_Cricket_Rig_04
  11. Open the Family Types dialog
  12. Create a new instance based length parameter, label it “Slope”
  13. Add the formula “(Slope*Run)/1”
    • Roof_Cricket_Rig_05
  14. Select three of the upper reference lines
    • Select the create form button
    • Select the surface option
    • Repeat for the other three upper reference lines
    • Roof_Cricket_Rig_06
  15. If desired, add a material parameter to the surfaces
  16. Save the file

Nesting Families

When creating families it is sometimes necessary to nest other families, and this is more common with adaptive families.  However, not all family types can be used with adaptive families. For example profiles, structural columns, or beams cannot be loaded into an adaptive family.  If a nested profile is needed, then a generic model family with model lines, either adaptive or not, can be used in lieu of a profile family.

A great family to consider nesting, especially when adaptive families are a new to the user, is the out-of-the-box “Diagnostic Tripod” family.  This family will display how the adaptive family is working once it is loaded into another family or project.

Repeaters and Divisions

If a family is going to be repeated, which is similar to an array, then nesting families is a must, as is using a divided path or surface.  The first step is to create a division from either a surface or a line.  To do this, select the element and use the Divide Path or Divide Surface command.  Since the 2013 products, a series of lines may be selected and divided as a single element.

DividePath

A divided path also has properties that will allow for a beginning or end indent.  These properties give further adjustment to the location of the hosted elements.

If a nested family will become a repeater, it will have to be an adaptive family.  To create this, first place the family on a point, or series of points, that was created from the division tool.  When doing this, make sure to select the node that was created by the division.  Next select the element and use the Repeat command (same button as array in a normal family or project).
