It looks pretty cool. I like it.

Them aliens are at it again.........there is that circle............

[SignTorch Vector Art]

Let's not insult any aliens. That circle is an arc with the start and end angle backwards. Arcs extend from the start angle counterclockwise to the end angle, on that arc the end angle was 2 degrees less than the start angle, so it turned a full 358 degrees instead of just 2 degrees as intended. I used a text editor to swap the 50 and 51 group codes, which effectively swapped the start and end angle, which corrected the problem. Some software just does that sometimes, the angles are usually correct, just backwards. Human error....

quote]thanks gary....that question about the circles that appear has been asked a few times and you are the only one that could give us an explanation as to why they appear when opened with certain software

I've done a lot of CAD drafting and DXF programming...

In this case, the problem is in writing not reading the DXF file.

It would be interesting to track down exactly what software causes that.

Hey Ironhorse what Alien software are you using?

[ironhorse]

It's crazy the cobra postedwirh the ring in it. I use plasmacam and had no trouble cutting it? Sorry about that guys

[SignTorch Vector Art]

oh, it's not your fault ironhorse, we were just wondering what software is doing that,

just for reference, can you post the pcm file?

now that we know what the error is, and what software caused the error, we just need a source file that triggers the error, in order to study possible causes/solutions....

i see this alot in my copy of plasmacam. with certain files it seems to trigger either a circle or on rare occasions a shutdown of the program.

Easy fix Ironhorse, I opened and just deleted the ring, I was just fooling around with the alien thing not trying to take away from your work, the art is amaizing.
