Question

3D Modelling of a fish

Note: Files are saved in Creo Parametric Student Version

 

Hi, I am attempting to create a 3D model of a fish for 3D printing.

 

I have a 3D model already (.obj file) however it doesn't seem to want to work. I would like to convert that .obj to a solid so I can edit it with Creo Parametric but I am having difficulties. I am not used to working with .stl or .obj files that make use of facets. (What I would like to do is split it into several parts (allowing for maximum printing area constraints on 3D printer) and increase the thickness of the walls.)

 

As that doesn't seem to want to work for me I am attempting Plan B. Please see attached a sketch of the fish (i.e. a 2D sketch in .prt format), the .obj file and a .prt file created by importing the .obj file and saving as a .prt. The sketch has been made by roughly tracing the outer boundaries of the .obj file. (It doesn't have to be perfect.)

 

If someone could advise the best possible way for me to convert the sketch into a 3D model (similar to the part created by the .obj file however with thicker walls) that would be fantastic. i.e. would an Extrude, Sweep, Revolve etc. work best?

 

Thanks very much for your time,

Ian

    I can get as far as 1:16 in that video following the steps detailed to create a skrinkwrapped model, as seen in Capture1 below, however as soon as I attempt to click okay the geometry disappears and I receive the message 0 triangles produced. This happens regardless of what Quality level I attempt to use. Has anybody any experience with receiving this message? Does anyone know of a solution?

     

    This is now added to the long list of different attempts I have done changing this .obj to a solid .prt, this is why I conceded defeat and attempted to create my own without much luck...
