Getting Object to Scale into Corel

[Chris Edens]

I want to engrave the attached knife scale. What is the most accurate way to get it into Corel at 1:1 scale?

I do this all the time. All I do is put the knife (or whatever) on my Canon printer's scan bed and scan it. The image I get in Corel is exact size.

From there I place the object in the laser where I'll engrave it (usually 2" right and 2" down from the top left corner using 3/8" thick x2" aluminum shims)..

then I put 2" and 2" guidelines in Corel, rotate the image as necessary to match the actual part, place the image against the guidelines, then lock the image.

Place your engraving withing the image, run a painters tape test run after you're finished with the engraving layout, then edit if needed. Most times with odd shaped items, no editing IS needed. :)

Thanks I will give this a try will this also work on a handgun?

You just have to make sure your scanner is scanning the image in at the same resolution Corel is setup at. If you are scanning at different resolutions, then it will change the size. Scanning does work well.

A Hand gun will be more difficult because its 3d and bulky but it will work. What I have done is lay the object on the scanner bed and cover it with a very dark cloth. Try to make sure no light seeps in from the sides. It will give you a good outline of the gun.

[Chris Edens]

Thats a good idea with the black towl. I wonder how a 3D scanner would work for something like a handgun?

My scanner inserts scanned images at exact size no matter the resolution of the scan- only difference is higher res looks better (and takes more time to scan)

-- I just checked, and in my scanner driver settings there's an 'output size' option, with actual height/width dims of the bounding box you're scanning into, and I can choose output % size- mine's set to 100%... I've never noticed it before! :)

Ya! I keep my scanner and corel at 300 dpi. bitmaps scanned and imported always come out exact. If I have a number of pieces to do, I use bezier points to outline it with a hairline, then cut one out of scrap plexi, and check the fit. (adjust and laser trim as/if needed) once the fit is right, I add the info as needed to the first outline, then duplicate it as many times as I can, and cut a multi piece template out of scrap. Insert the objects, and engrave away. And, save the digital template for the next time your doing the same job. The original template is charged to the customer as part of the setup costs.

if you have to photograph it rather than scan it be sure to include a good ruler in the photo so you can use that to scale the image once it is in Corel. Not perfect...but it will work get you pretty close.

Just last night I had to do this very thing, customer wants his name/address on some giveaway knives for a show this weekend-

I just put the 2 knives in the scanner, made sure they were as straight as possible on the scan bed, this is a screenshot is the result-

I just positioned the logo and wording to fit the blades, piece o' cake... I started with the small knives, and once clamped in the holder
I located the corner of the grind bevel with the red dot, put some guidelines at those coordinates (as shown above) and moved everything to the guidelines--
and repeated the procedure for the bigger knives...

and the engraving lined up perfectly! :)

Very nice Kev!!

[Kev Williams]

Just wanted to point out that I'm using a relatively inexpensive Canon Pixma inkjet printer with a scan bed on top,
doesn't matter the resolution or any other settings, as long as the output size is set to 100% (arrow)
it always scans into Corel at exact size. Makes it pretty easy! :)

For larger projects in Corel.... I did this Sign project and needed scale of the building for the Township Sign approval.... I placed a 4 foot Florescent Light box at the foot of the building and took a picture. Brought the picture into Corel and made 1 foot = 1 inch in Corel. Placed the letters and calculated the size.
