smoothing a curve

Post by loriny »

Hello Again
I am curious if there is a way to smooth an imported vector. (the curve was created by the probe on my shopbot following a cardboard template. The cut out arch fits the template well but it is very rough. Is there a smoothing function or something like that- or what is my best way. I tried shifting nodes but that is tough.
Thank you

Currently your only option within Aspire is to node edit by hand. In Aspire version two, due to be released soon, Brian has said there will be a "curve fit" function that will be able to reduce nodes and smooth curves.

Until then CorelDraw has a node reduction tool.

Hope this helps,

Hello loriny,

If the curve is rough due to the scanned points being slight misaligned by
the probe software or scanning process, perhaps the easiest way of smoothing the curve
would be to trace over it with the curve tool.
And then delete the original.
Select the Curve tool, click on the start point and a few points along the
scanned curve, a smooth curve will be created through the points that you selected.

A (very) rough example.

I hope that this helps.

Cheers,

Mark.

hi toriny

i have to use many times scanned stuff.... into the aspire you can pull in a scanned pic, and it has really good function to reduce brightness of bitmaps...
with this you can place ez a few node around your shape and use the bezier curves you can get the best result.... and it fast....
i used other programs, and my experience is the vectric somehow works more "handy" .... even you can optimize your contour with convert to arc of splines-beziers...
after i tried several tracer-vectorizer... i did not find really goodworking, because the human eyes works better :-)
ie; the computer can't decide where you want corner, radius, or when is a curve looks good...
