Need Help!- jpeg to dxf issue with gibbs.

[Moreton]

I use Image2Cad to convert images to .DXF files and then after importing to Gibbs I only ever get dots, I'm doing this to save time and having to connect every dot or make a lot of curves would take forever. Any advice?

For those wanting to get where I am download Image2Cad, open the image you want, invert it if needed then resize it ( otherwise the imported DXF image will be huge like hundreds of inches huge.) after resizing you'll want to sharpen the image a bit and then detect the edges for definition, process the image then save your DXF file.

You will need to experiment with settings in Image2Cad. I've used other raster to vector software and all of them never gave me perfect dxf files, always had to change settings and create a new file or create geometry once I imported into Gibbs. The issues are in the raster software, not the cam system.

[cadman]

Actually I should clarify, your results with raster to vector software are highly dependent of the quality of the jpeg you try to process.

Thanks Cadman.
I figured I'd ask this here instead of creating a new topic, something I'm having trouble doing in gibbs itself is creating a curve in a 3D model. Like say if I wanted to make a blade for a windmill, how do I make my curves that I did in XY, YZ, XZ or whatever into a solid of some kind? I know how to make curves and revolve them to create some effects but I cant seem to figure this out.

Here is an awful mspaint representation of what I mean.

Hey Moreton - This weekend I'll try to intepret your sketch into a model that is close to what you are looking for and upload it.

[Moreton]

I'm trying to learn how to do it, not have it made for me. I appreciate the thought that you would spend your time making it for me though

But ya you can't get anywhere if you don't learn.

[cadman]

Sometimes its easier learn if you have something to disect and visualize.

Using your blade as an example, you could create all surfaces then stitch and solidify them. The curved surface would be a Coon's patch. This method would take the longest to build.

The method you are using to create curves works well, but it is easier to create surfaces rather than bodies.

What I did in the VNC file is create two bodies, make two CS and align them where I needed, then make a circle, copy and translate it, and use them to create a lofted cylinder that I used to slice the longer body. I left the bodies separate. For this particular part, this seems like the fastest and easiest way to model it.

When I model complex shapes in Gibbs, I tend to use both surfaces and bodies.

I can't really tell you what you might be doing wrong with creating solids since I can't see what you are doing, but your geometry needs to be connected. Unconnected geometry is a common rookie problem. You also need to make sure the numbers you enter in the dialog boxes are correct. If you'd like, you can send me a file your having problems with and I'll tell you whats going on.

I'm also running 2007 gibbs so I can't open the file you made for me lol.

[cadman]

Here's a copy in V7.0

Are you having trouble with something in the wheel?

[Moreton]

Nah it was to show that I could make curves but I can only seem to do it in XZ making a curve and then revolving it and simply removing sections from the solid later.

Looks good
