Converting an image to trace - best way?
« on: December 11, 2016, 05:01:53 AM »
Trying to get a design we have in Illustrator over into T2 in order to burn the outline.

I can take the attached PNG into T2 and trace it with decent results however it then needs ot be scaled down to fit the work piece.  If I rescale in T2 the image is lower quality and then doesn't trace well.

Is there a way to edit/resize the original trace to different sizes?  Or what is the best approach?
I've had no luck with any DXF export so having to resort to the image itself.

Playing with this more I guess it can be adjusted by the resolution setting to scale the image down to the desired size.   Is this the best approach?

What you really want is a high quality DXF... so here it is.

You can import and scale it as needed.

FYI: I used Inkscape to trace it and then exported as DXF.

I am still curious as to why you can't export as AutoCAD R14 in Illustrator and get it to import correctly, is it possible to "explode" or flatten the file so it becomes a regular 2D drawing.

Edit: I searched for similar issues and found this, it may not apply completely as T2Laser works with most objects but a similar technique or clicking that export box may be the solution. Please let us know.

For those of you who may have the same issue as me, what you need to do in Illustrator is use the Object»Path»Simplify menu item, and then check the "Straight Lines" option. You may need to use the "Object»Paths»Add Anchor Points" menu item a few times before simplifying to straight lines gives you enough detail.

Thanks.  I've tried a variety of setting and DXF formats in Illustrator with no luck so far.  I'll mess with a bit more and see what I can do.

Thanks for the DXF as well.

I don't have any issues exporting DXF files from AI.  They just outline and don't export any fill.

Are you importing them to T2Laser?
