Polylines tend to have way more segments in order to support 3D extrusions better. Polylines and lwpolylines are both segmented line approximations in DXF to establish curves. Hadn’t paid any attention to which app I used to do the design in. I use both Inkscape (some) and Corel (a lot) and was seeing different behaviors - sometimes curves and sometimes segments. I’ll take a look at my Corel settings to see what they are when exporting (or Save As) DXF files. I haven’t gotten to my PC today to do any research into this and now you’ve saved me some time So for now I’ve tried it 4 times on four different INKSCAPE DESIGNS WHEN programming the toolpaths now so far selecting the geometries is one complete path now and not 30-40-50 chains for one 2” circle ,!!!, THEY IMPORT IN THE EXACT DIMENSION I designed them in, in INKSCAPEĪnd the Coordinate is set exactly in the right spot on the plane face I selected in FUSION. Last that the Major grid line every: is set to 1 ORIGIN X AND ORIGIN Y ARE set or left at -0.0000 Then I made sure that spacing X & spacing Y are set to 0.250” inches Scale is next and left at : scale X 25.4 user units per inch Orientation to landscape & units set to inches This results in the Bazillions lines of geometry you have select when toolpathing.Īlso be sure your scale is in inches which is the next selection.Īlso in INSCAPE WHEN YOU SET Your new document up Otherwise it creates multiple geometries around your sketchlines trying to assemble a com0lete geometry to match your import shapes. I unchecked this and selected use ROBO- Master type spline outputįrom all my research it’s seems FUSION needs the spline type ROBO output When saving the DXF you presented with the following:ĭefault seems to be the LWPOLYLINE option. The first and foremost one that seems to have solved the Problem of not having complete geometry to select was from saving the file from Inkscape. I took a few of the Forum FUSION design groups idea of how to improve svg and DXF file imports into fusion and tried them. There were tons of topics related to DXF import and SVG import on INKSCAPE and many other SVG editor software type including adobe, Corel draw etc… If you download to try make sure to select “Mach3 Plasma” under Options/Machine/Post Processor as this is the post generator you need to talk to the Crossfire.ĭ8782C74-F077-42EE-AC90-4B721DADAE1C.jpeg 480×640 99.4 KB So I’ve dived in this morning and did a lot of research on FUSION 360 Forum. What is also nice in Sheetcam is if you have any broken entities with just one click it will show you exactly where they are in your drawing. Then hit Youtube for tutorials here and you will be up and running in about 15 minutes! I highly recommend trying Sheetcam, free demo here. Then open Sheetcam, import drawing, select a tool (have made preset plasma tools), generate toolpath, Silulate if you want, then post to get G-Code and with your file that took about 3 minutes starting with saving you file. Yes, Sheetcam for creating Gcode…my process is thisĭraw up project in CAD, I have been using Deltacad for 20 years now, cheap, easy to learn and fast for 2D… PWCNC Tempess_airplane-opener-inches_0001.dxf (53.5 KB) OMG or atlest from what other software Im use to.įile attached simple bottle opener with a few intenal bodies to cut out.Īny input as to what im possibly doing wrong? When selection geometry it does allow the outline on some pieces to be selected only a bazillion smaller sections of geometry at a time all the way around… and internal geometry is same some ok some only bits and pieces.įUSION Is ridiculous for just trying to do 2D profile cuts. Import it into FUSION and CREATE the setup in cam on the X Y plane as in all LANGMUIR TUTORIALS I even set the stroke path down to under 0.010mm and or 0.001" so you cant even see it, then save it in DXF & SVG Ive used INKSCAPE FOR 98% Of my design and editing to run my wood CNC even Vectric software to import into and generate toolpathsĪll files I designed are bitmap traced then OBJECT TO PATH as this is standard for all coversion of png or jpg to run on CNC Ive already imported and cut the Langmuir files in the tutorial without issue.Īnything I design outside of FUSION then impot into Fusion for toolpathing is the problem Hello, I have been designing a few pieces to cut on the crossfire, but I am unable to get them to tool path correctly or consistently!! I have watched the tutorials on importing svg & dxf and have no issues with thatĪll the parameters are saved in inches and ive even tried and switched to mm before saving the file in svg & dxf.
