I am trying to make a 3d representation of a boat hull from a side profile drawing & separate hull cross sections.
I scaled everything how I wanted and traced cross sections and outline. I assumed I would use a NetworkSrf to accomplish this, but can never seem to select the appropriate curves in the right sequence.
I have seen the other “hull” posts on the forum, and unfortunately am still lost. How should I approach this? seabright_hull_help.3dm (4.6 MB)
For running calcs on the resulting hull, which is a much less demanding requirement than producing top end renders, I’ve been creating a GHS (text format) file with a little stations-and-offsets conversion program- could also be done with a spreadsheet and some macros- and importing that into Rhino, which automatically converts it into a mesh if you want. The volumetric properties agree well between the station-defined version, the tri patch version in Rhino, and an independent tri-patch calc on the result.
Attached is a screenshot of a sample result if an import of stations in the text file, which is click and done. (this was from a set of station definitions in a PDF, OCR’d and then checked briefly but not completely)
Sure. This ship doesn’t exist. It’s a hypothetical destroyer that was a student project.
It does have quite a few stations to get that level of detail.
The Rhino file and the .gf (GHS format) file.
If you want to try that path, I should also give you some help with the gf file format: it’s easy to write but very hard for a human to read because there are no visual breaks between successive stations. rhino-version.3dm (138.8 KB) ghs-version.gf (20.7 KB)
