Step 1. First, the Parametric Tower – Twisting Rounded Triangular Mass was used for the building element. The tower was intersected with floors to create the different floor levels. The geometric relationships were slightly changed and are shown in the screenshot below:
Step 2. To flex one parameter in the Parametric Twisting Tower, Dynamo was used. First the inputs were created where the model element is selected, the Base Radius is flexed, and the Gross Floor Area and Gross Surface Area is output.
Step 3. Next the BuildingForm.EvaluateSingleInput custom node was used to output the Gross Floor Area and Gross Surface Area.
Finally, the outputs created from the graph show the Gross Floor Area and Gross Surface Area for a base radius ranging from 20-120ft in 20ft increments.
Step 4. Next a new building form was created by using the Template – Twisting Tower – 3 Profiles. The original template used 3 triangular shapes for the profiles. To create a more interesting and form, the base profile was kept the same, the middle profile was changed to a rectangle, and the top profile was changed to a different triangular shape. The 3 new profiles are shown below:
Step 5. Next, Dynamo was used to flex two parameters, Mid Height and Top Height, and get the Gross Floor Area and Gross Surface Area values.
Next, a list of the pairs of variables was created.
Step 5. The custom node BuildingForm.EvaluatePairsOfInputs was used to find the results.
Step 6. The results are summarized in the tables below for 16 pairs of test cases:
