Revit curtain wall magic

In order to write down as much as I know about curtain walls I have separated  the elements into different blogs. There is a link at the bottom to the next one.

Always when I give Revit trainings I spend a lot of time explain the power of curtain walls. The standard Revit books I have seen are always a bit thin on the subject. In order for students and other people who are interested I'll write out what I tell. This way they can read about it.

Curtain wall basics
First you need to know that a typical curtain wall exist out of the following elements

  1. The curtain wall
  2. Curtain wall grids
  3. Curtain wall panels
  4. Curtain wall mullions

type properties of a curtain wall

  1. Wall function - very usefull for filtering your views. You won't right away see untill you need a way to show the difference between interior or exterior walls in a view. (or one of the other functions)
  2. Automatically embed - You need this if you want to use a CW as window or a door. This will cut a hole in the wall you place it in.
  3. Curtain Panel - here you set what kind of filling you want in between the mullions. Basically you have three options. See section panels below.
  4. Join condition - here you set which mullion has the right of way. (which one is allowed to continue and which one has to stop. (see mullion connections below.
  5. Structural material -  as soon as I figure out how you ungrey this parameter I'll let you know. (Althought I very much doubt you want to use it)
  6. Vertical grid pattern -  here you can set whether you want a pattern and if you do how it should be modelled. Be aware you need a gridline to place a mullion. 
  7. Spacing - In the image the spacing has been set to 3000mm so the vertical gridlines will be placed 3000mm apart
  8. Adjust for mullion size - see image. Basically when you turn this off the bottom and top panels are smaller than the other panels.
  9. Fixed number - when you set this parameter to fixed number then the spacing parameter gets grey out and that parameter becomes an instance parameter. This enables you to create the same curtain wall type but have a different amount of horizontal grid lines per wall.
  10. Spacing - is greyed out and controlled by an instance property
  11. Adjust for mullion size - see image. Basically when you turn this off the bottom panels at the vertical borders are smaller than the other. 
  12. In the first image there is an arrow pointing to where this mullion is
  13. In the first image there is an arrow pointing to where this mullion is
  14. In the first image there is an arrow pointing to where this mullion is
  15. In the first image there is an arrow pointing to where this mullion is
  16. In the first image there is an arrow pointing to where this mullion is
  17. In the first image there is an arrow pointing to where this mullion is
Instance properties of a curtain wall
  1. Number - Only available if you have set layout to fixed number, this sets the number of gridlines in the vertical or horizontal direction
  2. Justification - With this you control where you want the fitting piece placed
  3. Angle - With this you can rotate the gridlines
  4. Offset - With this you can offset the entire pattern by a value. You can increase or decrease the size of a fitting piece.
Next blog is Mullions
