Revit has specialized tools for selecting curtain
wall-specific components based on the grid lines they are hosted by, their orientation, family, or the curtain wall host and this
post explores those tools and explains how they are used.
Curtain walls, in Revit, are comprised of mullion, panel and
gridline components. These components
can be selected individually by hovering the cursor over one or more objects, tapping
the Tab key until the correct object highlights, then clicking the left mouse
button. Click here for a post on selecting specific curtain wall objects and some issues that may arrive.
Like all objects in Revit, you
can select the other object in the same family by right-clicking the mouse and
choosing Select All Instances > Visible In View or Select All Instances >
In Entire Project depending in the extent or requirements of the selection. This can be used to change all mullions or
panels from one family to another.
To select all mullions, regardless of family, along a
gridline, select one mullion on that gridline, right-click, then choose Select
Mullions > On Gridline. Your cursor
must not be hovering over another object when you right-click or the
context-specific menu will not show the Select Mullions option.
All the mullions on the same gridline as the original are now
selected. You can use Select Mullions
> On Gridline for both vertical and horizontal mullions
This selection method also works when gridline segments are
deleted by selecting the mullions on both sides of the missing span.
Similarly, with a mullion selected, you can right-click and
choose Select Mullions > Across Gridline to select all mullions that are
parallel to the selected mullion and run between the same perpendicular gridlines.
The other Select Mullions menu options include:
On Vertical Grid – Selects all vertical mullions on the
current curtain wall.
On Horizontal Grid - Selects all horizontal mullions on the
current curtain wall.
Inner Mullions – Selects all mullions that are not along the
perimeter of the
current curtain wall (jambs, sills, heads).
Border Mullions - Selects all mullions that are along the
perimeter of the
current curtain wall (jambs, sills, heads).
Mullions on Host - Selects all mullions in the current
curtain wall.
Using any of the five methods listed above will deselect
selected mullions if appropriate.
There are similar tools available for selecting curtain wall
panels; however, they are slightly more restrictive.
After selecting a curtain wall panel, right-click (being
sure not to hover the cursor over another object) and choose Select Panels >
On Vertical Grid. All vertical panels that
are the same size as the original and run along the same vertical grid line are
selected. Revit will omit any panels
that are not the same size.
Select a curtain wall panel, right-click and choose Select Panels
> On Horizontal Grid. All horizontal
panels that run along the same horizontal grid line, even if they are of a
different size, are selected.
As expected, Select Panels > Panels On Host selects all
the panels on the current curtain wall.
As you can see, there are several tools available to help
you select Revit curtain wall components by family, vertical gridline,
horizontal gridline, orientation or curtain wall. I’m just waiting for the Select All Mullions
Using The Old Die Designs And Replace Them With Mullions Using The New Designs
button. Now that would be
helpful!
