    Just so happens my cheap Chinese LaserSoft program will do just that, and I'm guessing RDWorks and any other Chinese laser program WITH a cut simulator probably will too...

    I typed in 'WHAT'S MY LINEAR CUT DISTANCE?' in 24pt Arial in Corel, imported to LaserSoft and entered it into the simulator; it came up with 754.58mm-
    here's a screenshot of the simulator-

    so the outlines of that lettering at 1/4" tall total almost 29-3/4" total length--

    I'd be glad to run some patterns thru my simulator, I use Corelx4- or you might be able to download LaserCut or some other software that will work in demo mode...

    Most CAD software has an "analyze" function or maybe "Properties" that will list perimeter, surface area and if the part is 3D it will tell you volume and can give weights based on the type of material. You should be able to get the perimeter pretty easily that way. If nothing else, dimension all the straight lines and add the numbers up, it should be pretty close.

    So Kev, I downloaded Lasercut, and imported the image, ran simulate and I come up with two sets of numbers. Total length and cut length. Pretty big differences in those numbers. I'm guessing I go with total length?

    NO, go with cut length, which is pure "laser on" distance-- TOTAL length includes "laser off" moves too! Just from home to work and back home can add LOTS of distance depending on where the actual work starts!

    Well I'm glad I asked!

    So for this one piece, it's 286.3mm (11.27"). But now I can't really find any info on these waterjets inches per minute calculation. Good thing the company that's selling them is going to give me that. I should know soon enough if a waterjet can beat my 13 minutes cut time on the fiber!
