I started by bringing in the plans using the image workbench and arranging the three views on the planes and aligning them. Kris - I liked your start and wanted to keep up with your posts. I tried to get thte ship module working and failed - no blame allocation as it could have been my understanding. My tree-view of this model also lacks structure and that makes it difficult to keep track of more then 300 points already.Ĭonclusion: I will try to start over the effort and use sketches from the start. I think you can only get that by using sketches that import these intersection points from external geometry (sorry if this sounds very FreeCAD slang). My network of curves, that looks quite OK visually, is far from a real network because intersection points of horizontal and vertical curves are actually not coincident. That was a disappointment and only resulted in errors. I wanted to use the Gordon-surface tool from the curves workbench to skin the network of curves. I made curves through these points both with draft splines and the tools from the curves workbench. The next picture shows this more clearly. Vertically they follow the location of the stations. They are arranged horizontally along the waterlines, half-breadth lines, top-timber line and topside. The exact difference between the two kinds is unclear to me. I used both draft points and part vertices. I must admit that it is a far too complex ship to start with, but my desire to bring such ship to live won from logical reasoning. It is for an English third rate ship (74-gun) from the second half of the 18th century. I want to share the current state of my FreeCAD work. ![]() Hoping that this will be of interest and that others will contribute. I plan to go back and show how this was assembled and then move forward on the issues. I have been inspired by some amazing work in other topics in this forum " CAD and 3D Modelling/Drafting Plans with Software".Īttached is a current rendering with many unresolved issues. The objectives of the project are to understand some techniques for getting the 3D hull built, to get as realistic rendering as possible, and explore the opportunities for 3D printing with various options. At some point photographs of the real schooner will resolve details. The project used as an example is a hull model of the New England fishing schooner Adventure and supporting information from and details from Howard Chapelle's "The American Fishing Schooner". Being relatively new to the 3D CAD scene, the approaches will be relatively simple and sometimes wrong and can be improved. Whether you are a hobbyist, a programmer, an experienced CAD user, a student or a teacher, you will feel right at home with FreeCAD.Starting this topic to explore the FreeCAD program and discuss techniques to be used. FreeCAD is designed to fit a wide range of uses including product design, mechanical engineering and architecture. It reads and writes to many open file formats such as STEP, IGES, STL, SVG, DXF, OBJ, IFC, DAE and many others, making it possible to seamlessly integrate it into your workflow. FreeCAD is a multiplatfom (Windows, Mac and Linux), highly customizable and extensible software. It contains many components to adjust dimensions or extract design details from 3D models to create high quality production ready drawings. FreeCAD allows you to sketch geometry constrained 2D shapes and use them as a base to build other objects. Parametric modeling allows you to easily modify your design by going back into your model history and changing its parameters. ![]() A free and open source multiplatform 3D parametric modelerįreeCAD is an open-source parametric 3D modeler made primarily to design real-life objects of any size.
