Kifanlo part2, creating cut sections

Boat Survey: Kifanlo parametric analysis


Built in 1955 in Les Sables d’Olonne, the KIFANLO was classified as a historical monument in 1984. She is one of the 16 identical hull trawlers launched by the Batifort shipyard between 1945 and 1957. The Kifanlo is a tuna trawler made of wood with mixed propulsion. She is 16.37 metres long, with a tonnage of 27.51 tons, and is equipped with a 120 hp Poyaud engine. (more at


The work is done with Rhino and Grasshopper in order to develop a tailored tool for 3D analysis.

Rhino Remeshing

First the 3D model is imported

The geometry is then remeshed using QuadMesh function.

In Grasshopper we can import the hull as a mesh

Then we can verify the proportion and the right dimension with a bounding box, we will also use this bounding box to create 3 axes X, Y, Z that will be useful to create our further sections.

this is the longitudinal horizontal axe

This is how dimensions are made

This is how sections are prepared. The longitudinal horizontal line taken from the cube is divided. The division is every 1 m

Frames created are intersect with Mesh

This slider allows us to refine the way we want the number of sections

With this set, we define the axial line that will be used to compare both sides of the hull

One the sections are made, it is interesting to project them on the XY plan (or any plan wished).

(Sorry for upside down dimension)

Then sections are spaced:
