For Solidworks you can extract the necessary 2D curves (vectors in Vectric parlance) by making a plan view drawing (.SLDDRW)—use an empty template, not one with information boxes, etc. Then export the result as a DWG file. Beware though that I have found that even if you tell Soldiworks to keep clos...
I haven't had a chance to look at the file but I would suspect that if you click on Material Setup in the toolpath sidebar you'll find a gap above the model. Make that zero in all should be better.
You might need to add a ubiquitous "zero plane" to make the edge cut smoothly.
Perhaps a screen shot of what you consider to be poor details might help us. Windows has a built-in snipping tool for taking screenshots and saving the image to a file. You can even draw highlights and annotations. The saved image file (png or jpg) can be uploaded as an attachment here. https://yout...
Good question. I suspect that unless you have a really specific problem and are directed to set it by support that it's an option you can safely ignore.
Without any comparator in the photo (e.g. a coin) it's difficult to tell whether the image should be rotated 180 degrees making the text "backwards" (flipped through a vertical axis) or UpsideDown (flipped through a horizontal axis). Having rotated the image 180 degrees it looks more natural than it...
If you have an automatic tool changer I can sort of see why you might want to group toolpaths from what are disparate projects. But, if you don't have one why wouldn't saving like cutter toolpaths separately and running them sequentially work? Unless you're zeroing off the machine bed you might have...
It could very well be that there are two in the originating program but they are grouped so appear to be as one. Or, if it is Illustrator, they might be a compound path that is "exploded" on export.
GIGO seems more likely than only some singles importing as duplicates.
