Creating Conceptual mass in REVIT and Creation of Sinusoidal curve and a Parametric stadium using Dynamo

Q.1 

Aim: To using dynamo create a set of sinusoidal points and create a curve and to create a surface our of curve: 

Step by step procedure as follow 

• Initially, open the architecture template of Revit software and go to manage tab.
• In manage tab select the dynamo.
• Then dynamo window opens and then go to new option. 
• Now, start the process by inserting three integer slider.
• This can be done by typing code block in the library search panel.
• One block is named start ( Value - as per you)
• Second one end (Value - as per you).
• Third one step (Value - as per you).
• Now, type range in the search panel of the library and insert it.
• Now, connect these three code block as input to the range block.
• Now, search points by coordinates in the search panel.
• Then, connect the range block to the x coordinate of the point by coordinate block.
• Now, we have to produce sin wave out of these points for which we have to insert sin function which is given by math.sin option in the library.
• Sin values are very small so, we need to amplify it. For this, insert another integer slider and name it as amplifier.
• This, amplifier code block needs to be multiplied to the sin block.
• For this, search product function in the library.
• Input for x value is sin block and for y value is amplifier.
• Next, we have to provide phase for the sin curve.
• So, again insert an integer slider and name it as Phase.
• Now, the phase block is theen added to the amplified sin block(*).
• For this, insert add operator block from library.
• Hence, the set of sinusoidal points are obtained.
• Now, we have to convert them to a curve.
• The curve can be created from nurbscurve.
• Search Nurbscurve in library and choose nurbs cuvrve by control points
• Now, connect the Points by coordinate block as input for the nurbs curve. A line will be developed connecting the points.
• Hence, sinusoidal curve is also developed.
• The next step is to develop surface.
• For this, first create a group of these items for easy manipulation.
• This can be done by selecting the required input blocks and then go to edit option in the top portion and then choose create node from selection.
• The entire thing will be grouped together.
• Now, copy this entire blocks two times to create the surface.
• Adjust phase to view the two curves that is copied.
• Next step is to create the surface.
• For this, first create a list.
• This can be done by searching list.create in the search panel of library.
• Then connect all the output of the sine curves as input for the list.
• This will serve as the input for surface by loft block.
• Now, we have to create the surface.
• For this, search surface by loft
• Hence, the surface is developed out of the curve. 

Q.2 

Aim: To create a conceptual layout of floor using dynamo 

Step by step procedure as follow: 

• Open a new architectural template.
• Go to manage tab and open the dynamo --> New. 
• Inorder to create the wall first we have to create four control points.
• For this, search points by coordinates in the search panel of the library.
• 1st one is named as origin (0,0,0) and the rest is named as control point 1(x,0,0), control point 2(0,y,0)  and control point 3(x,y,0).
• Now, provide two integer sliders to provide the values for x and y.
• Now, we have to connect these points by a line.
• So for this, search line by start and end point  and insert 4 blocks.
• The input for these blocks are the points created previously.
• Hence, the layout of the floor plan is obtained. 
• Now, search wall in the panel and choose wall by curve and height.
• So, for this input required are curve, height, level and wall type. Inputs are given as follows:
• For curve, combine all the four lines in a list by choosing list.create.
• For height, another number slider is chosen and name it as height.
• For level, search level in the search panel it will contain the levels availbale in your revit folder. Then choose the level in which you want to place your structure.
• For wall type, search wall type in the panel and it will display the wall types linked in the revit file.
• The floor plan layout is given below 
• Now, go to revit file to view the 3D form where the height of the wall is visible.
• The height of the wall can be adjusted using the slider.
• Now, we have to place the floor.
• For this, type floor in the library and select floor by outlinecurve, floor type and level.

Q.3 

Aim:  To create array model elements

Step by step procedure as follow: 

• Open a new architectural template in revit file.
• In that go to architecture tab --> Columns --> Architectural column --> Place the column (610mmx610mm).
• Now, similarly 16 columns are created.

• The properties of the model elements are varied using dynamo.
• Now, open dynamo.
• In the search panel of the library search select model elements, integer slider and set rotation.
• The integer slider is renamed as rotation angle.
• Now, select model elements block will be the input for family instance and integer slider ( rotation angle) will be input for degree. 
• The rotation angle can be varied to desired value.

Q.4 

Aim: To create a conceptual mass in revit and develop a parametric column

Step by step procedure as follow: 

• Open revit software and under the families open a new --> conceptual mass --> mass.
• Now, go to elevation view and create a level at 3.6m and name it as Height of roof. 
• Now, using spline tool draw the desired outline for the walkway.
• Now, we have to create a profile to sweep through the curve.
• For this, we have to set the workplane at the points and develop a polygon at the workplane keeping the point as centre.
• Now, a polygon is developed with point as center.
• Similarly, workplane and polygon is developed at all the nodes.
• Now, we have to create the surface which done through sweep. 
• For this, select all the polygons and the curve line and choose create form option.
• Now, select the entire form and then filter and retain only the form.
• Now, select the form --> divide surface --> Then provide the pattern (triangle bent).
• Now, open a new family -->Curtain panel pattern based.
• Now, select the pattern as triangle bent.

Q.5 

Aim: To use Dynamo to work developing parametric stadium

Step by step procedure as follow: 

Procedure:

• Initially open a new architectural template in Revit and then open dynamo.
• Basic parameters to design a high rise structure is created as input in dynamo.
• Four integer sliders is taken from the library for the following:
• Number of levels
• Floor to floor height
• Bottom floor rotation
• Top floor rotation

• Now, insert a code block from the library to combine level and floor to floor height and type 0..#levels..Floorheight.
• Now, connect the integer sliders named as levels and floor to floor hegiht as input to the code block.
• Now, search coordinates by origin in the library and insert it.
• Then connect the code block as input for z coordinate in the coordinate by origin block.

• Five points are generated corresponding to 5 levels.

• Now, insert rectangle by width and length from the library.

• For this, inputs requied are coordinate system, length and width.

• So insert integer slider for length and width.

• Then connect the inputs for the rectangle block.

• Now we have to rotate the geometry.

• So, for this insert the rotate block from the library. The inputs required are

• Geometry : Rectangle block

• Origin: insert an origin block from the library.

• Axis: insert vector Z axis from the library.

• Degrees: For this insert a code block and type Bottom..Top..#level. The inputs for this code block is already available i.e, Bottom floor rotation, top floor rotation and levels.

• Now, we have to create surface, for this type surface by loft in library.

• Then connect Geometry.rotate block as input for Surface by loft.

• Hence, the parametric stadium have been created

• The number of levels and width and length of the rectangle can varied accordingly.
