 | | Taking shortcuts —Ronald Vallenduuk
|
| | | As I've recently started creating parts I've been taking a closer look at how other parts have been made. I've noticed that sometimes there are overlaps that keep the file smaller. My question is: what is more important; having 'correct' parts or (...) (14 years ago, 20-Jul-10, to lugnet.cad)

| | | | | (...) There is no correct answer to this, just a lot of personal opinions and shades of gray. The LSC did ratify additional restrictions on library parts which mentions this - see (URL) (14 years ago, 20-Jul-10, to lugnet.cad)

| | | | (...) I'm not a part author, but from a rendering engine author's point of view. Those kind of overlaps can cause very ugly artifacts during rendering, so imho saving a couple of bytes (on harddrives containing 1.000.000.000.000 bytes these days!) (...)

My second computer came with a 100GB hard drive, but even after I bought that I was still seeing people (...) (14 years ago, 20-Jul-10, to lugnet.cad)

I ordered the 3-chip set from Intel (8080, the clock chip and the buffer chip), then used a bunch of SRAMS (no way (...) (14 years ago, 20-Jul-10, to lugnet.off-topic.geek)

Unnecessary polygons, even after being read in and converted into internal models, take time to process. I think you can see the difference in POVray render (...)

But on the other hand, "good" overlaps don't generate (...) (14 years ago, 21-Jul-10, to lugnet.cad)
