View Full Version : Driving me crazy....

Hello,

I have one of those Corel (X5) issues that is driving me crazy.
I wold be grateful for any suggestions.

I want to make a grid that combines vertical and horizontal lines.
I will be make several in the future of different sizes and with
different spacing between lines.

Please see attachment

I want "A" and "B" to combine to make "C"
with no overlapping areas at the intersections.

The lines will all be vector curves with no color fill and black outlines
which will always be "hairline"

My concern is that I do not want the intersection points where
the lines cross to be engraved twice. So the finished grid will
be one piece with no areas that are engraved more that one.
If the areas where the lines intersect are engraved both vertically
and horizontally, those areas will be over marked there and provide
for a dotted look I don't want.

I have tried as separate lines grouping, combining, simplifying etc..
But I am still not convinced that the resulting image does not have
has overlapping areas. If they do not overlap I would think that
when separated, the lines would have gaps in them where the
intersection was removed like a dotted line. They still look solid
tom me.

Sometimes, when I have tried simplifying the grouped vertical and
horizontal lines, it looks like one group of lines had been separated
into a curve with the correct number of pieces but there is no gap.

Confused? Me too.

Any suggestions greatly appreciated.

Thank you, John

Although I understand what you are trying to do, I'm not quite sure why. I haven't seen any appreciable difference in a hairline that has been engraved in two directions, such as when two lines cross. Granted, it may engrave a bit deeper, but I can't see any circumstance where that would be a problem. Care to expand a bit and explain why this is a concern?

Hello Gary,

I am burning paint off of glass. Very touchy.

Not enough power-not all of paint is burned off.

Too much power (or double burn at intersections)
glass can fracture.

Thanks for you interest.

Not sure if this REALLY works with REAL hairlines, but... Take the set of vertical lines, copy, paste, rotate the 2nd (horizontal) set 90, select both, use Arrange->Shaping->remove Front from back (theoretically leaving just horizontal lines with gaps where the verticals were), then paste (as you still have the original, unbroken, verticals on the clipboard). Since a hairline does not have any real width (unless you use a near hairline of say .001), trying to edit the result seems to give Corel a bellyache.

Try the table tool.

Have you tried the "Step and Repeat" tool?

I used Oberon CurveWorks "Cut Curves at intersections" to get the attached results.
I find it works best if you start with 1 point line width, after "Cut Curves" you can change line width.
This break all vectors up but, the start and end points will still overlap. You may have to nudge the end nodes off of each other to get the effect you're looking for.

Is it really that tricky? I would think that it takes a lot
more power to fracture the glass than it would to remove
a layer of paint. And is the laser beam effect on glass
cumulative like it is on wood? would double burning on
glass have any effect at all? (if it were a setting too low
to fracture it in one pass)

I don't know .. just seems like there should be a wider margin
of power between 'not quite removing the paint' and fracturing
the glass.

Thank you all for your responses. I appreciate it.
Neal's "Curveworks" looks like it will fit my needs.

Thanks again,

John

I think it would be faster to raster.
