Parametric bench

Hello everyone,

Does anyone know how to create benches like tthe ones below STRICTLY USING PARAMETRIC FORMULA?

Kind regards,

Dirang

How exactly would you want this to be parametric? Looks like a one off bespoke item in which parametrics would be of little use...

Within a family that would be very complicated and one heavy family in a project.  Your best bet would be using massing and Dynamo. http://dynamobim.org/.  Dynamo is a very good tool for complex shapes and changes on the fly.  Now there is a little learning curve to get over but once your past that its a great tool.

I have absolutely no idea. But I do know that forms can be created out of the profile lines of other forms.

what @chrisplyler briefly described is the right way to approach such design. It make it parametrical, you will need to put some trigonometry and algebra into it. If you need to randomize it

1. Manually ... Those points should be easily controllable by their Normalized Curve Parameter (either manually or by dependent formulas)
2. OR Use couple of adaptive points to act as attractors which control the the NCP of those points depending on where you host them (if you are confident you can model/handle adaptive families)
3. OR Use Dynamo as somewhat suggested above and what the script does basically is randomize the NCP of those points based on a certain given input (although you do not really need to - what you have is organic in shape but pretty much basic so you do not need to complicate it.) a similar concept we use for automatic kinetic curtain panels where the given input in such case is the location of the Sun which the script fetch from Revit (a little bit of Python scripting might be needed unless someone compiled a node in Dynamo that does it all - I haven't come across any thou)
