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

Ans 1

Procedure: 

• 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 a Code Block to define start end and step value.
• Now, type range in the search panel of the library, insert it and connect the three value

• 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.

• 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 then added to the amplified sin block(*).
• For this, insert Add operator block.

• Now, this is then connected to the y coordinate of the points by coordinates block.

\

• 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 and degree
• Now, connect the Points by coordinate block as input for the nurbs curve and insert an integer slider for degree. 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.

Procedure:

• Open a new architectural template.
• Go to manage tab and open the dynamo New file.
• 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.

• 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.

• 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.

Procedure:

• Open a new architectural template in revit file.
• In that go to architecture tab then Columns then Architectural column then Place the column
• 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.

Ans 4:

Procedure:

• Open revit software and under the families open a new then conceptual mass then 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 then divide surface then provide the pattern.

• Now, open a new family with Curtain panel pattern based.
• Now, select the pattern what you have selected.
• Then, create a reference point at centre of the face.
• Then draw a circle of radius 3" at that reference point.
• Now, select the pattern, refrence plane and circle created and choose create form.

 

• Now, load this into the project.
• Now, select the enitre form of the walkway and filter it to retain only the divided surface.
• Then in the pattern select the family that we have created just now.

Procedure:

• Initially open a new architectural template in Revit and then open 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.

• Twenty points are generated corresponding to twenty 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 create surface, for this type surface by loft in library.

• 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.

• Hence, the parametric stadium have been created.
• The number of levels and width and length of the rectangle can varied accordingly.

• In revit structure is visible as follows:
