Would like to be able to delete the unnecessay parts of the trace. I would like to edit away all of the unnecessary junk and be left with just the part. trace to bitmap- which produces a lousy vector with a lot of junk besides the part. Either way, it only approximately relates to the shape in the raster I think we need a bit more step-by-step detail on what you've actually done to create the image you've got, and what you actually want to achieve. The larger shape in the SVG file is a single path which is either not the result of a trace bitmap, or was perhaps created using centreline tracing (I haven't got any experience with this yet, as it's a feature of the alpha version, not the current stable release). The raster image and the SVG don't seem to have a direct relationship with each other. I'm not really sure what the attachments are showing. So yes, tracing can end up with a group - but not a useful one if you want to remove part of your shape. My point was that tracing a shape made up of multiple parts does not end up with a path for each part, all nicely wrapped in a group rather you end up with a single path combining the separate shapes as sub-paths. Some options (such as the multiple scans) produce several paths which end up in a group. Yes, I should have been clearer in my statement. Otherwise, the gcode will have the unwanted path in it. If you have already used the one the produces the gcode, you'll probably need to re-do it, after deleting the unwanted part. It looks like you're using the Gcodetools extensions.
Then switch to the Selection tool and deselect everything, And then you should be able to select the part of the path that you don't want, and delete it. Then select the new nodes, and click Break Path at Selected Nodes button, on the Node tool control bar.
You can do that by double-clicking on the path with the Node tool (after you already click on it once, to select it). If there is not already a node on either side of the part you want to delete, you'll need to add new nodes. If that's the case, you'll need to use the Node tool. Unless you mean you want to delete part of a path? So you should be able to delete whichever part you want - the larger or smaller path. You can see it by selecting the larger path with Selection tool, and looking at the status bar. Although I'm not sure if it comes from tracing, in this case. So what you said is true for some options, but not for all options. I've noticed lately, that using certain options, the results are not grouped.
In the past, every result from Trace Bitmap was grouped. Depending on the image being traced and the options used, the results might be grouped. At least not with Inkscape's Trace Bitmap. It's not a group of objects, so ungrouping won't work. Tracing a bitmap produces one single path (which may be made up of multiple sub-paths).
