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

1.

Aim:

To create a set of sinusoidal points, a curve and a surface out of the curve using dynamo.

Procedure:

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 integer block in the library search panel and selexct 3 nos.

One integer ( Value - 12),

Second integer (Value - 650).

Third integer (Value - 10).

Now, type range in the search panel of the library and insert it.

Now, connect these three integers as input to the range block.

Now, search points by coordinates in the search panel select 2 nos.

Then, connect the range block to the(a) 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.

Then, connect the range block to the Math.sine.

Then, connect the range block to the another (b) x coordinate of the point by coordinate block.

Now, type product in the search panel of the library and insert it.

Now, type code Block in the search panel of the library and insert it and give value as 50.

Then, connect the code block to the (b) Z coordinate of the point by coordinate block.

Then, connect the math.sine to the (b) Y coordinate of the point by coordinate block.

Then, connect the math.sine to the X of the product.

Then, connect the code block to the Y of the product.

Then, connect the Product to the (a) Z coordinate of the point by coordinate block.

Now, type Nurbs curve by control point which has 3 units in the search panel of the library and insert it by 2 nos.

Now, type List in the search panel of the library and insert it add 1 more item.

Then, connect the (a) Z coordinate of the point by coordinate block to the (a) Nurbs curve by control point.

Then, connect the (b) Z coordinate of the point by coordinate block to the (b) Nurbs curve by control point.

Then, connect the (a) Nurbs curve by control point to the item 0 in the List.

Then, connect the (b) Nurbs curve by control point to the item 1 in the List.

Now, type Surface by Loft which has Cross section in the search panel of the library and insert it.

Then, connect the list to the Surface by Loft .

Hence, the surface is developed out of the curve.

Result:

A set of sinusoidal points have been created as follows:

Sinusoidal curve connecting points is developed as given below:

Surface is developed out of the curves as follows:

2.

Aim:

To create a conceptual layout of a floor plan in dynamo.

Procedure:

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 Point by coordinatecontrol points.

For this, search points by coordinates in the search panel of the library.

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.

This can be viewed in 3D view in revit file.

Result:

Hence the conceptual floor plan layout has been developed and is as follows:

3.

Aim:

To create an array of model elements in revit.

Procedure:

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.

Result:

The array of model elements have been created and their properties are being varied through the blocks created in dynamo.

4.

To create a conceptual mass in Revit and develop a parametric column by dividing the surfaces.

Procedure:

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).

Result :

The conceptual mass have been created in Revit and is given as follows:

5.

Aim:

To develop a Parametric Stadium using dynamo in Revit.

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.

In revit structure is visible as follows:

Result:

The Parametric Stadium have been created and is as given below:
