Is it possible to get the calibration patterns in DXF?

Postby rich0550 » Tue Apr 19, 2011 3:24 am

I tried converting them to illustrator then to dxf with no luck. Maybe I did not use the right option solidowrks opened them as all black and as images even though was a dwg or dxf.

also tried a pdf to dxf converter but the circles came out jagged.


Was hoping to use a router to scribe the dot placement.


Thanks much

Hi Rich,

I have converted from Inkscape to dxf and managed to open as splines in Blender 3d, so it should be OK for you.
Just unzip the file. Let me know if this works

Nice job, Thank you. I will have to look into Inkscape. That came out perfect. You did not need to edit it correct?

Hi Rich,

Inscape is great.

I imported the pdf onto the page, scaled it down to the page size, rotated to portrait and then "saved as" a dxf. That simple.

cheers

Hi Guys
I want to make panels according to my use and what I have. I just got a print out on A4 paper (left side) and measure it. I got sizes according to pic. Would someone confirm that I got right dimensions or not? I want to use same scale on big wooden panels. Want to paint the panels and paste the points with glue.
The scale I measured is 150mm.

Hi,

the vertical distance between the centers of the markers has to be the same as the horizontal. So if you want a scale of 150mm it has to be 37,5mm (150/4) also in horizonal direction.

Is the diameter of the points and circles is important?

No, it isn't. Simply magnify or reduce the dots (inner and outer diameter) in about the same scale as the whole calibration sheet is changed.
