    I got a copy of the raster image at the top of the post and saved it as a bitmap. I reduced it to only 2 colors (1 bit per pixel) and changed the white to dark green. Then I opened that into the display of LaserBoy. I used LaserBoy to render the text as vector font impact.ild. It's not a perfect match but it's kind-of close. Then I moved each character into roughly the right place over the bitmap and stretched each character in x to get the letters to look more like the logo. In another frame, I manually placed vectors around just one loop of that shape thing and copy rotated the other three loops. Then I went back to the text frame and exported it as a bitmap. I opened that in a raster editor and flood filled it so the letters were solid black and everything else was white. Back in LaserBoy, I opened that as a mask to black out the loop shapes that appear to be behind the text. Then I merged the text frame into the loops frame and optimized it.

    It isn't perfect and once I went through the whole process, I figured out how to do it. So I could do a much better job.

    All software has a learning curve usually proportional to its capabilities and unique features. Pointing with a mouse is in no way easier than tapping a key.

    I thought the font looked different. That looks like a lot of work...

    It's not really. I didn't have to draw any of the characters. I just moved and scaled them into place and I only traced one loop and copied and rotated it three times. Like I said, once I finished it, I figured out the process. If I did it over again it would look better and take less time.

    So, masterpj, are you going to answer my question? What's the point of telling people not to use LaserBoy? Why? What do you get out of posting that?

    That looks great! I'm gonna wait til I have sometime to recalibrate my laser. It has 40k scanners so should have been able to do something looking like that.

    As for the whole LaserBoy chat, thats all way over my head atm.

    It would be nice to chat about how to actually make something with LaserBoy.

    I'd be glad to help you with that.
