Dimension Comprehension

Reverse Engineering Progress

Update One

Got started with converting the three-dimensional object into a two-dimensional one with measurements. I wanted to start with the simplest part so that I could get some momentum built.

I was able to measure most things but their definitely was an element of best guesses and trial and error comparing the object to what I saw on screen. Like 0.5 fillets for example, I wasn't able to measure them but I think I got close.

Then the momentum kicked in as expected and I forgot more regular documentation but here's some mini milestones I documented.

The biggest issue I had was the internal bottom diameter of the filter wasn't possible to measure. So I held the digital caliper above it, tried my best to look square on and estimate it. Once I started to boolean difference out the windows for the filter I saw the bottom was too narrow. Using some of the references from the new geometry I was able to get a more accurate diameter, or at least one that looked more accurate.

There was also an interesting moment where I thought I had messed up building the CAD models using my measurements because the angles looked off but then when I picked up the object itself the angles actually matched, which made me feel pretty good about the measurements.

This is my progress so far.

Mesh Filter

This is how I accomplished the mesh filter.

It's a surface with a material that uses the Rhino "Crosshatch Bump Texture" at a tiny scale.

There are many better ways to do this but this was easy enough for me and I was able to get the result I wanted.
