Grasshopper is a great tool for parametric design. You can almost design anything you can think of(keeping the structural parameters aside). Especially using the Attractors- Curve/Point, one can design a flexible parametric object/structure.
Louvers have always been planar- vertical/horizontal. Even though non-planar louvers have not been seen in implementation yet, I think it would be a real deal in the coming future.
Non-Planar Louvers
There was a post by Kwee How in his blog explaining "How parametric design contributes to “new” architecture and to us?" He's shown various 3D printed miniature parametric models and parametric louver is one of them.

The following tutorial by Christopher McAdams explains in detail how to design non-planar louvers in grasshopper that can be adjusted using a curve attractor. And he also explains the possible fabrication of these louvers though not in 3D.
Often times, when you get data from a source, there will most probably be something incorrect that needs to be fixed using an ETL process of Power Query. And most of those transformations would require either Replacing or Removing string's that are not necessary. For example, if you extract any financial data from a source which has multiple currency symbols, there's a chance that the numbers get extracted along with the currency symbols like "$700"/"€700" instead of 700. And these type of cases makes it tough to Transform the Data to our wish as the value will be considered as a text instead of a number. In those type of cases, we would most likely have to create multiple steps to remove the multiple currency symbols from the Column. But thanks to the solution provided by Marcel for one of the questions posted on Stack Overflow, with a little manipulation of the Query language (M), we can replace/Remove multiple strings in one step using the List. ...
One of the best natural examples for a Voronoi is the Wing structure of a dragon fly.Grasshopper can help us to build a shape like this in Rhino. Image Courtesy: The Pond blog Grasshopper by default has a node for Voronoi, we just have to prepare the necessary information to feed into the node. The following example shows how to create a Voronoi shaped holes in a surface Create a planar Surface from rhino or grasshopper Randomly Populate the surface with points using the Populate 2D Node Feed the surface and the points into the Voronoi node and feed a number slider too to adjust eh radius This forms the required Voronoi structure which you can edit the number of points or radius. To create the holes we need to offset each and every inner portion towards its centre using the Scale node We can find the centre of each of the inner portions using Area node I'm not sure why but using the offset command su...
Though in Grasshopper Offset and Scale are two different node functions, when it comes to a planar surface, the results of the both are similar. But, I found the " Scale" node to be effective when you want to loft the resultant curve with another. The following images show the different results of a Voronoi structure that yielded when scale and offset nodes are used. When the Offset node is used When Scale is used
In any Revit project, the orientation of the North is always set to the top of the screen. But this might not be the case with all the projects. All the projects are not oriented parallel to the North direction, and we might want to orient the project to the true north direction. In one of my previous posts, I have explained the difference between Project North & True North and how we can use them in any project. In this tutorial, I'll show you how to Set/Change the Orientation of True North. Go to any Plan view. Go to Manage tab in the ribbon and click on "Position" drop-down in the "Project Location" toolbar. Then choose "Rotate True North" from the drop-down list. Rotate True North This will show you 3 different ways to change the orientation of the True North. They are 1. Manual Rotation Upon clicking the "Rotate Ture North", Revit will automatically prompt you for manual rotation of the orientation. You can use...
