Reverse Engineer: Part Two (Modelling the Flashlight + Renders).

February 25, 2024

Process:

Measurements - ongoing throughout the modelling:

Modelling:

Starting out with the measured outer diameter, then extrude. Then I realized that the top was slightly smaller than the bottom, so I made two circles and then lofted them. With the proper offset for the thickness of the flashlight. But you can't, or I least I couldn't, loft all four at once, so I had to do the two pairs separately and then make them into one object afterward.

Organizing everything

Then added in the thicker parts, and measured the space between the two so that I could properly space the two of them.

Added in some circles, so that I could loft them to make the slanted parts of the thicker parts of the flashlight.

Then I started making some shapes so that the bevels would be the right size - the rectangle is to get the right width.

Then making the rough shape of the bevel.

It happens 8 times, so setting that up and extruding them so they extend up to both parts since they line up on the flashlight.

Did the loft.

Rhino crashed/froze

But I learned my lesson with the kettle and I saved, in more ways than one. I saved normally and made copies of progress (everything in purple).

First cut attempt on the bevels.

Second cut attempt.

Patch attempt

Rhino crashed yet again

Found a solution

Making them more curved

Cutting

Minor cutting problem - the slanted parts wouldn't cut.

fixed it. - It didn't like the way I was selecting things, so I had to be more careful with that.

Merging all the edges together so it's one piece.

The cuts left open holes, so I had to redo some stuff and use one of my backup models to redo it so that part of the red cutting parts are left behind to close the holes.

I couldn't fit my calliper in here to measure the depth properly, so what I did was I put my finger in there and drew a line and then measured that to get the depth.

How I measured:

Then doing the lights

Starting the batteries

Fillet

Another cylinder for proper detail

More Filleting

Small dot detail

Stacked

Doing the silver cutouts. This part was quite tricky to get right.

Get the right dept.

I Couldn't figure out how to get rid of the gaps, so that is for later.

Starting the top

Measurement for the height of the domed part of the button

Button done

All the threads

Shell for the bottom to make where the spring is inserted.

Starting the base for the spring

Spring parts

Piped and attached together. It isn't perfectly accurate, but I'm happy with it. At least for now.

The entire cap together.

Made some spheres to make the indents on the cap.

Forgot to make the part where you can attach the loop and clip to the cap. So made the right diametre cylinders to make the cut outs - properly spaced apart.

Then a small hole for where you would attach the loop.

Back to the indents.

And finally coming back to the indents on the base of the flashlight. Made a planar surface from one end to the other and then used the patch tool to make surfaces for the rest.
