I was missing the piecewise linear approximation of the higher order
shapes part.
I don't know the answer.
My instinct is that for arcs the direct analytic tests for proximity and
intersection are faster tests on an accurate piecewise linear
approximation. But on the other hand, if you only
I don't think you are missing anything. I was thinking that converting
everything to line segments might make DRC faster. I haven't dug into the DRC
code, but perhaps it relies on collision functions provided by the shape type
itself (which theoretically could be either "true" arc calculations,
Interesting idea. It might be a false comparison since we are choosing
between a line segement chain and a curve segement chain composed of
only lines.
For the maths aspect, the computational speed is equal.
For optimizations involving memory footprint and data structure
traversal speed, I'm
Hi hauptmech,
Would you give more details about the Altium import? Are you working on
a plugin or standalone tools? What do you plan to import (sch/pcb/libs)?
Regards,

Is SHAPE_LINE_CHAIN a core element that potentially an ARC might be translated
to for display, DRC, or other output needs? If so, it seems that they would be
separate with a conversion function from ARC to SHAPE_LINE_CHAIN and there
would be SHAPE_ARC_CHAIN or SHAPE_SEGMENT_CHAIN (or similar)
At first glance it looks like SHAPE_LINE_CHAIN and TRACK are the points
where the development clings to straight lines the most.
One could add a single variable to line segment data structures so that
they could also represent arcs.
or
One could add a layer of abstraction so that curves

Hi,
Sure, it would be awesome if
I asked earlier this year whether there was any interest in arc tracks
and got little response.
My use case was importing altium files.
Are any of the core developers likely to accept work in this direction?
