Revit Parametric Modeling
To create a family component dimensions are either locked, forcing the lines to remain a set distance apart or made into type dimensions, uniquely labelled and set a numerical value related parametrically related to one another.The Revit model lines rely on the establishment of parametric relationships, reference line are set up and dimensioned.
Once a working parametric relationship has been established mass modelling components may be introduced.
constraints tool bar
The constraints tool bar has been set to allow for the visibility of each individual mass to be turned on or off.
volumes are set for each mass;
This becomes the final result of the parametric equations. Being predetermined figures, in our case taken from precedent case studies a user can be confident that whatever resulting form-studies will equate to their original input.
Each uniquely labelled dimension is parametrically connected to its related labels, a few dimension modifications has a flow on affect within the model. These effects have been determined from the analysis of the pie-charts of experiment 1.
The mass is able to move and change shape in all six planes that constitute the rectilinear mass, subsequently each plane must be locked to the reference line that will govern its movement.
This enables a multitude of possibilities as the masses move and change updating from the entry data, easily modified by the user. A rapid massing tool is created allowing for the manipulation of unique form while maintaining a specified volume.
The volume of each shape is parametrically related using formulas to manipulate the 3 - dimensions of the mass.
