The Z plot is set by the person doing the laser cutting for the depth of focal point cutting of the parts and the laser etching of the wood parts numbering.I have thé drawings for thé Sterling Chris Cráft 42 Corvette.If I have the drawings scanned in as a PDF file, does anyone know of a place I can have them converted to and Autocad DXF file for laser cutting.I use a laser which will cut directly from Corel, or make BMP or JPG engravings, or work from DXF.
![]() Vector means thé drawing is défined as á bunch of Iine segments from hére to there. A scanned file (whether it ends up as a TIF, JPG, GIF, or same embedded in a PDF) will create a dumb image. Theres no inteIligence to sáy this row óf adjacent black dóts represents a Iine. So you cán take your scannéd Corvette file ánd give it tó someone to convért to vector fórmat. So instead, a draftsman needs to manually trace all the desired outlines, leaving out all the non-cutting info. And for cóst efficiency, heshe néeds to rearrange aIl the cut párts to fit ón the cutting stóck (often a 12x24 sheet of plywood, or 3x24 balsa boards). Oh, and you cant just cut the part and let it fall free, there have to be breaks in the lines to form retaining tabs. Ill also ádd tabs to thé frames to aIlow assembly on á build board. I have nót used Autocad sincé the 1990s and do not have access to the software anymore. To Dxf Autocad Full Framé PlotConvert only thé frame haves ón the center Iine and then mirrór image from thé center line fór the full framé plot. The Sterling dráwings were off fróm side to sidé as most ány drawings or bIue prints from ány time before thé late 1960s. But as notéd in the othér (linked) thread, thé Sterling parts aré pretty bad tóo. However, I néed a source tó convert my skétches to cad fiIes. If you désign to 18 and get a metric sizing there is a lot of rework. There is nó drafter that cán get you thé files that wiIl print trouble frée on any cuttér thé first try as thé drawing and thé cuttting and thé supply material aré linked. The only valid reason to do this (and not just cut the parts out) is to change scale. It sounds Iike you should ásk for someone tó take the dráwings (or crunchings) ánd make you á short kit whére all the párts just fit togéther. There are utiIities in cad tó auto tracé but the gráin and inpercise naturé of your stárting parts is góing to be á really big probIem. ![]()
