Curtain Walls in Revit are strictly a Family of the Walls Category. Then you have Types for each type of Curtain Wall. What if you want to select all Curtain Walls at once? You can’t multi-select types in the Project Browser to do this, but…
You can make a suitable Schedule to do it. Here’s how:
Make a new Wall Schedule
Only add the Family data field
In Sorting / Grouping tab, Sort by: Family and untick ‘Itemize every instance’
Now, in the schedule, click inside the Curtain Wall cell, and
Use Highlight in Model to select them all
You could then use Save Selection, or Temporarily Isolate Elements in View, depending on what you want to do next.
Revit Wants you to use a good, clean, consistent technique when setting up Curtain Wall mullions for high quality detailing. Here is one way to set these up for nice corner joins – the advantage is that the curtain wall can be properly ‘joined’, you do not need to Disallow Joins and hack the glazing position:
When finished, and the endpoints share a common location, the corner looks like the figure below.
Why is this preferable to assigning a single mullion to one curtain wall and leaving the adjacent curtain wall without a mullion? That would require that the edge handle of the CW without the mullion to be manually aligned to the edge of the mullion where it crosses the panel’s path; a feature that should be automatic in Revit. Changes to the mullion profile won’t necessarily be reflected in the open-ended CW and is an opening for errors. via Jon McFarland at CurtainwallBIM: Mullion Halves
HyunWoo Kim describes how to make a Curtain Wall that has actual curved glass panels (uncommon, but possible) by making a Curtain Wall type with a Basic Wall as the Curtain Panel masquerading as Curved Glass. He adds Wall Sweeps to the Basic Wall type to “pretend” to be Curtain Wall Mullions.
I have used a similar method to make curved Balustrades / Railings (making a Rail Type that is actually the glass panel and apply Glass material to it).
From Philip Chan’s blog: The concept is simple, I make a Generic family (it can be any category actually) as a solid (in this case, just a simple extrusion), let the family intercept the curtain wall, then use “Cut Geometry” to cut out the curtain panel. Once I made all the cut in the curtain wall, I have a yes/no parameter to control the visibility of the solid so that I can “turn off” the solid. As a result, it would appear that the curtain wall is cut out by a void. The good news is you can use the same family to make multiple cuts and it will work on the mullions as well.
I get pretty excited when a new Revit blog comes online – is that sad? Revit: Down to the Details has put out some cool posts since it started two months ago, particularly related to fine detailing and also a few posts on rotating curtain panels – both Pattern and System based.
In the words of the blog author, MerryMan: I pride myself at being very efficient at creating Revit components and sometimes going a bit overboard when it comes to creating some of the details of the object.
Martijn is starting up an interesting series of posts about Custom Curtain Wall creation at RevitForum Blog – it would pay to follow this series of posts.
In part ‘zero’, he establishes some groundrules that any decent Revit user will be interested in reviewing. I was particularly interested in his Family creation guidelines. The workflow he presents may look basic enough, but if you do things in this order, you may save yourself much heartache and re-work. Check it out:
When creating Families, there’s a set workmethod:
Draw the desired geometry layout in Reference Planes and/or Reference Lines
Dimension Refplanes / Reflines
Add parameters to dimensions
Flex parameters and check if they don’t break
Add geometry and immediately assign it to a subcategory
Add more parameters to define geometry and add data.
In Family Creation, parameters are placed in one of the following views:
