Hello, I'm new here on this side and sorry my English is not so perfect for talking about special questions. How I can transform a curved mesh to a flat mesh so I can cut it and get the right dimension for fixing it on a product. I'm designing a Trimaran and I have the 3 d mesh from the hull and I need this to make it flat to cut it. thanks for your advice. I'm using autocad 2010 right now.  |

You could try the FLATSHOT command but I am not entirely sure it will give you exactly what you are looking for. Another method would be to configure a DXB plotter using the Add-A-Plotter Wizard. Refer to this article for further details. https://knowledge.autodesk.com/support/autocad/troubleshooting/caas/sfdcarticles/sfdcarticles/Flatten-3D-model-to-2D.html One more option would be this program.... http://www.black-cad.homepage.t-online.de/abw_eng.htm ------------- "Humans have a strength that cannot be measured.

Hello Elang and John, you said that you want to "get the right dimension for fixing it on a product". I suppose that you want do develop the 3D mesh onto a flat metal sheet or so. I have already tried to explode 3D mesh but it's not working. A real 3D mesh won't be developable onto a flat sheet unless with distortions under some metal machinery. Eventually see my AutoCAD file : RIZZA_01.dwg in the CAD/BIM Blocks which is the development of a "square/round" that could give you some ideas. I don't think that FLATSHOT works on non real solids as 3D meshes. Some softwares like "logitrace" offer the possibility to "open" on flat sheets 3D solids, you choose a sketch, enter your datas and you get a 2D AutoCAD.

It could be done in Inventor though. ------------- "Humans have a strength that cannot be measured. This is John Connor. If you are reading this, you are the resistance." <<AutoCAD 2015>> |

| Yes John, I see now that Elang has Inventor, I hope that the mesh he is talking about is OK with Inventor ( that I don't know at all but if it's working like Solidworks could do the job if the CAD operator knows the way to do it right ). |

Or he can check out the program I gave him the link to. At least he has options. ------------- "Humans have a strength that cannot be measured. This is John Connor. If you are reading this, you are the resistance." <<AutoCAD 2015>> |

Hello John, thanks for your replay. Unfortunately with the flatshot command I don't know what to do. Looking and trying the link you send me I stuck with problems. DXB File I don't know how to create and PCP as well. Right now I can not use inventor because my laptop with this program was stolen. Thanks  |

The FLATSHOT command is explained in your AutoCAD Help file. The explanation on how to create a DXB file was fully explained in one of the links I provided. The other link to the black-cat website and the custom lisp program for unwrapping a surface or a mesh is just something I stumbled across that looked interesting. I have no experience with the program. You can always download the 30-day trial of the latest version of Inventor and use that. Maybe you have taken on too great of a task with this drawing and should consider abandoning it for the time being until you have more experience or better resources or both. ------------- "Humans have a strength that cannot be measured.

Hi Elang, can you post a sample here? I'll see what I can do for you. Hi John, have a look at the actualization www.ant-ares.de too. (I hope I will not be banned for this hint ) Regards Jochen |

Wasn't that the site I provided the link to? ------------- "Humans have a strength that cannot be measured. This is John Connor. If you are reading this, you are the resistance." <<AutoCAD 2015>> |

Yes - the basics are the same. But i hope, ant-ares looks more professional... Jochen |

Hello Jochen, enclosed I sent you a picture of my project. I stay in Indonesia and are from Germany too. This year I will build a beach trimaran for sailing on the nice beaches we have here. Regards Peter Michael |

Sorry - cannot see your picture here. Better to publish the dwg here to to sent it via www.black-cad.de Regards Schöne Pfingsten! Jochen |
