    My first frame designed in SolidWorks

    Somebody's gotta give Charlie a run for his money.

    Here's my first personal project since buying SolidWorks 2012 this summer. It's basically version two of the 650b frame I built at UBI earlier this year. I've learned a ton about the software through the process of completing this frame design. I'm prepping myself for a return to a career in product design and development with an emphasis on solid modeling.

    That frame looks great! Very solid!

    Maybe you can shorten a bit the chainstays...

    Are you going to model the whole bike?

    Frame: Columbus Spirit with carbon seattube.

    Despite the real angle of the seattube, the virtual one is 74, because it joints to the DT instead the BB.

    With this configuration, the frame has 370 chainstays (pretty short...).

    The weight should be around 1200 grams.

    Thanks, Carlos. The chainstays are 425mm. The frame I built at UBI has 420mm chainstays, and that did not leave enough room for a front derailleur. I figure adding 5mm to the chainstays and using a direct mount front der ought to work with this frame design.

    I am working on modeling other bike parts. It would be nice to eventually be able to assemble the complete bike in SolidWorks. Modeling a riser handlebar with bulged clamp area has been a great learning experience. I will share some of these parts here as I model them.

    Just after my comment, I thought about de FD and you are right. Anyway, 425 mm is pretty short and those 5 mm extra should not change the behavior of the bike.

    Im looking forward to see those parts.

    Regarding my project, here you have the frameset, with the fork from my latest bike.

    Thats right! I was not thinking in JRD, but since Im fun of their works... the idea of the ST meeting the DT just came up.

    I was fitting the wheels to the frame, and some parts (old and new), with the idea of modelling a 17 stem and maybe doing something new in the drive-train.

    Suggestions, comments?

    Since the colour design was a bit classy and boring, here you have a more fresh version.

    New paintjob and decals, new crankset and stem.

    I have to finish the seatpost, and maybe I can model a Rotor oval chainring.

    Hey;

    You really have gotten quite good at this. It is only down to tiny details to really portray a super realistic image. Round rims without flat tires even!

    How about paying some attention to the seat? It appears to be polished anodized aluminum with a razor sharp leading edge. It would seem to be more realistic if it had a soft surface look with seamless shadow gradients and soft round edges.

    Thank you for the advice.

    Here you have a new render with some mods: saddle material and edges, mini-seatpost, headbadge and model name (Galician word, BTW).

    I'd really wish I had you CAD skills.

    I make loads of things, but it's all based on a few notes, and what can be drawn on the back of a napkin.

    Like my latest carbon frame, is based on half a sheet of A4 of scribbling and doodles.

    Lately I've stepped up a bit, and quit on used napkins though

    Hi again, here you have the definitive version, with the fork in orange, new orange tone and yellow decoration in the saddle.

    I hope you like it.

    VERY nice;

    I like the seat and the new orange. Like the new background a lot. Warmer, brighter, and more interesting without infringing.

    Super detaily fussy opinion stuff -

    - The light source (window/door) derived shadow further adds drama, interest, and realism without infringing. However, I would move the bike back from it (even just a little) so that these elements did not intersect. Or, move it forward so that they overlap more completely. With items like that, make them completely seperate or more completely integrated (at least 30%) because very partial engagement like this fools the eye by making the two conflict instead of harmonize. I hope that makes sense.
    - Also, the edge of the shadow on the floor should be soft along its entire length. Perhaps more in focus (crisper) as it nears the light source, but not hard edged anywhere as it is in the lower half here.
    - I find the stand distracting, but that's kind of picky. Perhaps changing its color - even very slightly - would allow the bike to stand apart from it a bit better. It sort of blends into the rear wheel too much. That might be my problem with it. Worth playing with anyway.

    Very nice work.

    OK so it's not a frame...

    ...but at least it goes IN a frame.

    Lace that wheel up! Hehe.

    Actually it looks good. Which SW are you using for modelling?

    Waiting for more images....

    I'm using SolidWorks for my models. I only have the standard version, so I can't do photo-realistic rendering, unfortunately.

    I've seen spoked wheels modeled. Maybe some of them are yours? I may try it eventually, but it's not a priority right now. I wonder if people can actually model a laced wheel accurately, bends and all. That would be a trick!

    I model the wheels with the lacing, but I think I dont do it accurately, or so accurately as a real wheel, but they are pretty close (IMHO).

    At least with radial and 2X patterns, its easy to do.

    Exactly. Its for having a more comfortable TT for your shoulder.

    Here you have the frame again, but with a tiny mod in the TT and the right CS.

    This is how it goes for the moment.

    Im thinking about doing the fork again, because I think this one has very thin legs.

    It has purple singlespeed Chris King hubs, Thomson seatclamp, and 3T components (Dorico, ARX and Rotundo).
