Hello, I want to draw the plastic part under the watch glass. I am having difficulty with the curvature equation. Can you help me? I am using an iPad.
It looks symmetrical, make a mold and cut key area of the mold to make cross section.
If its a famous watch I would just look for replacement I can buy.
You can import a picture to use to sketch over. Make it square in the frame and directly overhead.
Do you have a digital caliper to make measurements? Measure corner to corner, top to bottom & side to side. Make some construction lines to match for reference points. You can use the scale tool on the image to make it match the construction lines.
I would start with top and side arcs.
You can use the Mirror tool AND the Move tool to duplicate lines using your construction lines as axis for mirroring etc. Move tool can duplicate while rotating an object or line.
Finding the original “curvature equation” may not be an option.
I have found that when reverse engineering, often you can intuit the radius of an object by measuring and making assumption about e.g. a hole diameter if I you measure 5.93mm its likely a 6mm hole.

Thank you. I used paper for reference drawing, sharp lines created a certain line. I finished the drawing. But the concave slope is not complete. I will print it as it was when I chamfered it twice and share the information again.
