Deconstruction progress pt. 2

This week I continued to model the Bic Lighter.

I found some exploded diagrams on the lighter to find some of the elements I may have forgotten and better understand the shapes I am trying to create.

I then got to recreating the plastic holders that protrude from the casing though I am unsure how to curve them to fit the oval shape of the casing. Tracing a horizontal image using the picture frame command and the poly line tool and control point curve tools.

Later I found there is a cap on the bottom of the lighter used to trap the gas so i began doing this simple model.

extruded and caped oval

complete with the gas cap nub

Now back to the jet valve that i wasn't very satisfied with

tracing the outline of the jet valve I was able to better recreate the form. once I revolved a single side.

Here i'm inserting a cylinder to Boolean subtract and create a proper valve

yay.

I decided I should also model the child lock found on new lighters

I began creating the shape with use of the control point curve tool to approximate the shape.

Then curve extruded the shape

I still have quite a bit of work ahead and I am still very confused as to how to recreate the "hood" (large hollow metal piece where the flame exits) and same for the oddly shaped "fork" though i have created a 2D outline of it

(pictured below).

"fork" 2d

Finally I need to have everything measuring the proper dimensions in rhino.

Well... time to get back to work 😵.

Deconstructing an iconic American design

For my reverse engineered object I chose the Zippo lighter, invented by George G. Blaisdell in 1933, the lighter is a staple of american design and symbol of american military history, the design virtually unchanged to this day. Zippo lighter seperated from shell I chose this object because It is small and easily deconstructed (mostly: i have to figure out how to take apart some inside parts of the lighter if i choose to model them). looking into the lighter I also chose this object because I can see the shapes that would make its form in Rhino such as the cylinder flint lighter and the holes drilled through the lighter module that would involve subtracting cylinders from a round cornered hollow rectangle. the lighter component I'm going to have to learn a great deal about three dimensional modelling to execute this correctly but it's going to be fun.

Deconstruction of a lighter: Progress

For my reverse engineered object I had first chosen a lighter though after realizing I could not take it apart without destroying it I chose to the "Bic" lighter, a commonplace lighter sold around the world. (Flick my Bic? that just sounds wrong) (The Bic Dissembled) Oval shape for the lighter The Lighter body curve extruded and caped overlapping and oval with and oval trim to the shape of the red plastic lighter gas button and metal flame housing Post triming Once curveextruded we have the two approximattive shapes I then created the springs using the "spiral command" and counting the spirals on each of the lighter springs./ extruded cylinder for the easy to model flint flint capped and shaded gas nosel approxamitive shape Spark wheel: a circle and 60 pointed star Curve extruded rigged parts and center cylinder caped spark wheel Everythin...

Lighter deconstruction: Final Render

The beginning of the end, i started measuring all my pieces with my digital caliper then readjusting my measurements in rhino or creating models from the start point. Here is the "fork" component, creating through tracing an overhead views of the piece, then extruding and stacking them together, this was one of the hardest parts to recreate and was simplified due to very difficult to recreate minuscule details. the "hood" part, another challenging element created with the fillet, bool eon intersection and bool eon difference tools. the wall edge needs to be slightly rounded to be 100% accurate but has proven problematic to achieve. The flint piece, a simple extrude circle. The flint spring a spiral that has been applied the pipe tool The longer fork spring, again a spiral that has been applied the pipe tool The "jet" piece for where the gas exits and flame exists, another update from the prev...
