Wave Loft and Perforation

Hi all.

Almost completely new to Grasshopper and was hoping to get some help on my first project. Any help would be greatly appreciated :)

I have a face/ surface on the side of a gable roof form which I would like to perforate (with an attractor curve) and add a wave loft effect to.

I have attached a simple rhino file, a screenshot with the mentioned surface highlighted in red and a reference image of an existing bit of architecture with this effect i'm looking to create.

Any visual help with an explanation would be very ideal.

Thanks.

Hi Zeid,

since the top edge of your facade is not a straight line, but a zigzag shape (even with a vertical piece in it), it'll will be somewhat difficult to create a single loft which is exactly coincident with this top edge. See wave interiors and kinky boundaries tend not to play well together.

Do you need the top edge to remain completely planar?

Hey David,

Thanks for your reply.

I see what you're saying. Ideally, the edge should be as planar as possible where the wave lofting diminishes towards the edges as illustrated (in black lines) in this picture:

Although if that is difficult, perhaps the edge could have some relief too as illustrated above in blue and as can be seen in the example below:

Instead of lofting, you can use a surface from points approach. This will allow you to move all points near the facade edge to the same plane, thus ensuring a planar edge. See attached.
