Parametric Folding Panels in Revit and Dynamo
Download the Sample Data-sets here
In the Applications menu, go to New > Family, select "Curtain
Panel Pattern Based" and click Ok.
Select the blue grid in the background, and change the grid dimensions to 2500
for Horizontal Spacing and 7000
for Vertical Spacing. (See below image)
Start by hosting two
points on the default reference lines as denoted in the below image.
Multiple-select the two new points; in the Properties menu, click the
drop down menu to the right of
the "Measurement Type" parameter and change it from "Normalized
Curve Parameter" to
"Segment Length".
Set the segment length to 5800mm.
Set the segment length to 5800mm.
In the Properties
Menu, click the small button to the right of the "Segment Length" parameter
(See below red arrow). The "Associate Family Parameter" will open. Click on "Add Parameter", make a new instance Parameter, call it "OPENING_HEIGHT_REMAINDER" and click OK to close the windows. This parameter will be used to control the movement of the selected points.
Extrude the line 1000 mm and copy it 3x upwards. Divide each surface to 15 divisions vertically and 1 division horizontally.
Congratulations!
(See below red arrow). The "Associate Family Parameter" will open. Click on "Add Parameter", make a new instance Parameter, call it "OPENING_HEIGHT_REMAINDER" and click OK to close the windows. This parameter will be used to control the movement of the selected points.
Add two more points as indicated below and repeat steps 3.2 and 3.3
accordingly. Set the Segment Length
to 2900mm.
Multiple-select the two points from the previous step, in the Properties
Menu, click the small button to
the right of the "Segment Length" parameter (See below red arrow).
The "Associate Family
Parameter" will open. Click on "Add Parameter", make a new instance
Parameter, call it "PIVOT_HOST"
and click OK to close the windows.
Open the Family Editor by clicking the Family Types button (See red
arrow below).
Under the Formula
column, add the following formula to control the "PIVOT_HOST" parameter: "OPENING_HEIGHT_REMAINDER
/ 2".
Under the modify tab click on "Set" (see below red arrow) and
pick the xy-plane of the "PIVOT_HOST"
Point highlighted in the below sketch.
Place a point on top of of the "PIVOT_HOST and drag it slightly up
by pulling its z-axis icon, then
repeat the previous step adding one more point to the second
"PIVOT_HOST" Point. (See below image)
Multiple-select the two points from the previous step, in the Properties Menu, click the small button to the right of the "Offset" parameter (See below red arrow). The "Associate Family Parameter" will open. Click on "Add Parameter", make a new instance Parameter, call it "PIVOT" and click OK to close the windows.
Select the dimension, click on <None> near "Label" and select "<Add parameter>". Now type-in the new parameter name "PANEL_HEIGHT"; make it Instance and check-mark "Reporting Parameter" as indicated below. Hit OK to complete this step.
Multiple-select the two points from the previous step, in the Properties Menu, click the small button to the right of the "Offset" parameter (See below red arrow). The "Associate Family Parameter" will open. Click on "Add Parameter", make a new instance Parameter, call it "PIVOT" and click OK to close the windows.
Next we will create a Reporting Parameter dimension. In order to do
that, hit "DI" on your keyboard
to activate the dimension command. Under the Modify tab click on
"Set" and select the
xy-plane of the reference line as highlighted below in yellow.
With the Dimension command still active, click on Adaptive Point no. 3
then Adaptive Point no. 4 to place a dimension (Your
dimension should read 7000 mm as below).
Select the dimension, click on <None> near "Label" and select "<Add parameter>". Now type-in the new parameter name "PANEL_HEIGHT"; make it Instance and check-mark "Reporting Parameter" as indicated below. Hit OK to complete this step.
Open the Family Editor and click on Add parameter. Make a new instance
parameter and name it "OPENING_HEIGHT". This parameter needs to be grouped under
"Constraints". To do that, click
"Dimensions" (marked with a green box in the below image) and choose "Constraints" then click OK to close
the window.
The "OPENING_HEIGHT" parameter will appear immediately in the
Family Editor. (See below image) Click OK to close the Family Editor and continue.
Open the Family Editor by clicking the Family Types button (See red
arrow below). Click Add under
Parameters to make a new instance parameter and name it "HYPOTENUSE".
Now we need to parameterize the realistic operation of the panel as it
will open and slide simultaneously
using the Pythagorean Theorem for right triangles. (See the below illustration)
Open the Family Editor and add the below formulas to the Parameters
grouped under "Dimensions".
Also make the OPENING_HEIGHT 1200 mm and click OK to close the window.
Mimic the below
sketch by creating Reference Lines between the corresponding points.
Referring to the below image, select the Reference Lines highlighted in
yellow and click the Create
Form button then select the extrusion option from the bottom of your screen.
Select the top face of the extrusion; in the Properties Menu, change the
"Positive Offset" parameter to
50 mm resembling the actual thickness of the panel. Alternatively, you can
click the Associate Family Parameter button and make a new parameter which may be named "THICKNESS".
(See below image)
Repeat the previous couple of steps to the reference lines selected in the below
image.
Your end result should appear as below.
Start a new
Conceptual Mass family. In the massing environment, sketch a model arch similar
to that resembled in the below
image.
Extrude the line 1000 mm and copy it 3x upwards. Divide each surface to 15 divisions vertically and 1 division horizontally.
Load the KTS Panel into the Mass family.
Repeat the above step to the third set of divisions from the bottom
(below highlighted in blue); again
in the Properties menu, make the "All Grid Rotation" parameter to
180º.
Multiple-select the all the surfaces; click the Type Selector and select
the KTS_Panel which you have
loaded-in earlier. Your Panels should appear as below.
Start Dynamo and follow the below definition to produce the panel-opening variations.
