Objectives For This Project:
Understand the difference between vector and raster when using a laser cutter
Demonstrate fluency, proficiency and safety when using laser cutters
Hone 2D drawing skills in CorelDraw
Create bitmaps in CorelDraw
Thoroughly document the engineering design process in a project from start to finish
Lincoln Loud Conversion:
In Corel draw, I converted the Lincoln Loud raster image on the left to the vector image on the right by tracing the bitmap.
Practice Conversion:
I practiced converting a raster image to a vector image again in Corel Draw.
↪ Original Logo
↪ Vector Logo
Choosing My Logo:
I went to google to find a logo that had my initials (image to the upper left)
I copied the image
I pasted the image into Remove.bg
I downloaded the resulting image
I measured the dimensions of the leather keychain (image to the right)
I measured it to be 2.17 in at its widest and 4.32 in at its highest
I made a new document in Corel Draw with a width of 3 in and a height of 5 in
I imported the logo image into that document
I selected my image
In the upper tools window I selected "Trace Bitmap"
I then selected "Outline Trace" and then "Detailed Logo"
I adjusted the settings so that my vector image would come out most similar to the original one (image to the lower left)

Bitmap Conversion
In the settings under
Trace Bitmap->Outline Trace-> Detailed logo
I chose 100 Detail, 48 Smoothing, and 33 Corner Smoothness. I deleted the original image because I was satisfied with the turnout of the vector image.

↪ Vector clipart of the leather keychain
↪ Finished outline of the leather keychain
Keychain Outline
I used the photo of the leather piece I took earlier
I opened it in CorelDraw
I went to trace the bitmap and turned it into clipart
I then adjusted the settings
I turned the lines into hairline
In the color bar to the right, I removed the color within the hairline line area
I adjusted the measurements of the CorelDraw outline to match the length and width of the real one
Adjusting Position for Printing:
My designated box was in the upper left corner. I first considered the position of my keychain on the vertical (y) axis. The origin point on CorelDraw is on the bottom left corner and the origin on the laser cutting machine is the upper left. I measured the center of the cutout to be 4.5 inches down from the upper left corner of the carboard. Subtracting that from 20, because of the differing origins, gives 15.5. On CorelDraw, I selected my image and set the y variable as 15.5. There was no horizontal ruler in the laser cutting machine, so I had to approximate the x position. In a lapse of proper judgment, the point I chose was actually too far left to be within the boundaries of the box.
↪ Vector logo design with the outline of leather keychain
↪ Image of my final rastered leather keychain. There were not any obvious differences between my digital design and the final physical product other than the color changes.
The raster process was different than my previously used vector process because the materials and settings were different.

↪ Cardboard testing of my keychain design
↪ Image of my keychain in my cardboard cutout. I cut a bit too far left of the given box.
One of the problems I encountered was in the process of making the outline of my keychain in CorelDraw. I had trouble removing the color from the vectored image. When I selected the vector image and clicked on the ∅ symbol to remove color, my entire image would disappear. I resolved this issue by converting my lines to hairline. Once I did that an outline showed up and I could delete the color filled within said outline.
