    Question Very Basic Scale DXF Question

    Hello all and thanks in advance for your patience and assistance

    I am very new to this BobCAD program and thus far I am adapting fairly well. The question I have is when I merge a DXF file into v17 no matter the original dimensions of the drawing it comes in at like 300+ scale and then I must then scale it down to scale 1 in order to have an accurate cut of course. The problem is I am only seeing the ability to scale both length and width simultaneously? So how do I or am I able to scale either just the length or width of the original merged drawing independently?

    Hi,

    I am not familiar with BobCAD, but I had a scale problem in the past that I solved by scaling the objects prior to exporting rather than after importing into the CAM software I was using at the time. Just a thought, although you would think there would be the ability to scale individual axis in BobCAD. Good luck with it.

    Thanks Steve and yea I also thought of that but in order to have the drawing at 1:1 in BobCAD I had to scale the original drawing down to microscopic size. And when that occurs it then doesn't accurately import the drawing into BobCAD A vicious cycle for sure but thanks for the input and I will keep at it as we all do

    awm, You might get a quicker response at the Bobcad forum. I read a post where the Bobcad guy told someone to post there as their technicians monitor that forum.

    Very true buscht, guess will try to post it over there as well just from what I have seen (read) they are not always the quickest to respond but I guess if I don't post they cannot respond right? Thanks for the suggestion :cheers:

    They monitor this forum as well and most of the moderator are Bobcad users.

    Hi AWM,

    I will have a look if there is a way to do it via geometry. There is a way you can do it so your g-code scales correctly. In the nc-cam setup under coordinates there is an area where you can scale the output coordinates for the g-code.

    EG: If you have geometry that is a square 4" x 4" on screen you can leave the geometry as is, but get a scaled g-code output.

    Under the setup _ coordinates_scale, if you set X : 1.0 , Y : 0.5 you will get g-code that will contour a X4" x Y2" square. If you set the scale to X : 0.75 , Y : 0.75 you will get g-code that will contour a 3" x 3" square. If you then want to transfer that into geometry for your saved records you can highlight all of your g-code text and under the nc cam edit function select geometry from g-code and you will have the scaled item. I will try to figure out a way to reduce the amout of steps for this process. I will also try to see if it is possible to write a script to perform the function you want. If I can do it via script I will make it available up here for everyone with compliments from the BobCAD world wide staff.

    AWM, there must be something wacky about the units you are using in one program versus the other. Check that you are using the same size units (mm, cm, m, or inches, feet) in both programs.

    There is also never any need to draw in any program with any scaling factor except 1:1 When you say the part becomes microscopic in Autocad, this has me suspicious. All part proportions are relative..........

    CNC dude is right this is not a technical support site or a forum for support for Bobcad software, but it is a site for people with technical questions to get answers. The original post is not a support question, but "more of a how do i" question.
