DXF Export

    Am I missing something.
    I need to export a part in DXF format, but can not find this format in the export file menu.
    So I ask how can I export a part in DXF format?

    2D DXF export is available from 2D drawings.

    Richard -- What are you trying to Export in DXF?

    3D DXF has never been supported in Alibre Design - if that's what you are looking for.

    I used Wizo to create a PCB, which I want to send to my PCB program. Which then I send to my PCB house, to etch the pattern for me.

    The PCB program can only accept DXF files, so I to need turn this part into a DXF file.

    The bars on the bottom side will be transferred to the bottom layer (GND Plane) of the PCB and the bars on front (data bars) will be the top layer.

    The part file is to big to upload so here is a link. https://www.dropbox.com/s/i63329s4a08kctj/DeicerUnitSelectorPCB.AD_PRT?dl=0

    I have include the Wizo script if any one wants see how I did it. Any comments will be welcomed.:cool:

    Hi Rocket,
    I export to DXF like this:
    - Make a drawing with scale 1:1 on a blank page.
    - Export that to DXF.

    As far as I know it is not possible to export DXF directly from a 3D object (which is normal to my thinking as DXF is a 2D format).

    Richard -- You mean like this? You Export it fro, the Drawing -- not the Part!

    Thanks

    Converting to a drawing and saving it as a DXF worked.

    A CAD program from another company that I use once in a while allows the user to left-click on a part's face and export directly to a DXF file. That's proven very handy for me lately. Has Alibre given any thought to incorporating that sort of feature into the program?

    I'd like to piggyback onto this thread with a related, but different question. Have any of you successfully used the 2D DXF export to send parts to vendors doing laser, waterjet or CNC cut outs of planar parts?

    There is a vendor near me that uses a waterjet machine to cut out parts from plate materials. They require the parts to be sent electronically in DXF format. They prefer to arrange the DXF-defined parts for efficient cutting in their own software. It sounds like the Alibre export from a blank drawing as Don (dwc) described it should work. Has anyone tried such a thing?

    Are there any "standard" settings for DXF files that I should be aware of, and honor, in my exports from Alibre? I'm not familiar with the internals of DXF at all other than to know it's a standard Autocad format.

    Thanks,

    Make sure the views you provide are scaled 1:1, otherwise you may be surprised at what gets made from your file. And select a version of Acad DXF that they can open on the receiving end, there are several listed in the export file type list. Usually Acad 2000 works but you should ask which they prefer.

    Thank you, Harold.

    As Harald said, 1:1 scale and ACAD DXF 2000 and I have never had a problem.

    Got it, Don. Thank you.

    If you send your file to get cut/made somewhere ALWAYS add at least on dimension as not all CAD programs export/import the the same dimensions

    Yes! A big +1 for this!

    Yes, of course, without a question.
    I always send a dimensioned drawing pdf along with any computer readable files as one never knows what havoc updates etc. can cause.

    I have three CAD/CAM programs. One of course is Alibre Design, aother is a BobCAD/CAM the other is SheetCAM. I cut my teeth on Alibre Design many years ago long before I had any dream of having a CNC machine of any kind. Fast forward 20 years plus and here I am designing parts and also machining the parts I’ve designed with CNC machines.
    As far as the dreaming up of an idea, experimenting with drawing a part, creating and incorporating the idea into an assembly that functions with assembly constraints, there is no doubt, no question about it, Alibre Design is superior to any other,hands down!!!
    Now back to your dilemma of exporting to a DXF file? Alibre Design falls short in this area. In order to get the DXF file I need from an Alibre part, I save the part as an IGES file. I can then open the IGES file in BobCAD/CAM and convert it to a DXF file.
    A lot of the machining I do is with a CNC Plasma machine running TAP file extensions (AKA, G-Code tool paths) which are created by SheetCAM from the DXF file that I created in BobCAD/CAM Sounds like a lot of work but once I started doing it this way it’s really not bad.
    The point I’m getting at is you can save your Alibre Design part as an IGES file and I would bet that most CAM programs out there can convert the IGES file into a DXF file to run the machine that you need to make your part.
    In the meantime if someone on from the Alibre Engineering Department is out there reading this please wake up and smell the coffee! Saving a part to a DXF file should be a standard feature on Alibre Design.
