Pattern hole along irregular shape

[Anonymous]

Hi,

I have an irregular tapered lofted shape (see attached) and I am trying to create patterned holes all the way round in four rows (see attached drawing). The shape is hollow and the holes must go through to the inside surface. I apologise if this is simple but I can't work out how to do it! I am new to the forum and would appreciate some guidance. 

Kind Regards,

Luke

Hi! This should be fairly straight forward. You need to create multiple parallel workplanes from the top or the bottom. Then create a 3D Sketch > Intersection Curve -> pick the work plane and the Loft body. These curves can be used for patterning. Create one of the hole. Then use Rectangular Pattern command -> select the hole -> select the 3D curve as direction. Please feel free to attach your attempt, if you cannot figure it out.

Many thanks!
