Best way would be to scan it if you have a scanner available (most modern printers scan as well) otherwise a photo will work but make sure you're as square on to it as possible.

Rather than use the inbuilt trace function I prefer to manually trace over the top of the imported bitmap using the drawing tools as I get much cleaner results that way.

I bought some intarsia plans, which came in a 24" x 36" size. I had FedEx scan them and put into a pdf file. From there, I was able to use various software like Aspire, Adobe Illustrator, Coral Draw, Photoshop, etc to get the vectors I needed.

If you do this place rulers along the length and width of the drawing. That makes it easier to get things scaled and squared.

If you have an Android phone (I don't know about and Apple version), take a look at the Microsoft Office Lens app (https://play.google.com/store/apps/deta ... s&hl=en_US). This app allows you take an oblique photo and then rectify it. Imagine taking a photo of notes on a whiteboard while sitting off to the side of the whiteboard. This app will "square up" the photo. Overall, I've been happy with the results although text can be a problem at large oblique angles.

I'd draw some control points on the pattern with known distances and angles between them to check for skew / rubbersheeting. A square surrounding the pattern is a good start. And the square border will help the app rectify the image. Then I'd take a photo in Office Lens and use the resulting image for tracing.

I was able to take a picture of plans, I took them outside out of the direct sunlight. It cut down on shadows and gave me crisper lines.
Here is first try at setting tool paths, i just have a little to cut by hand until I can setup my other tool paths.
