Default Vertical cuts on 3d model

I made a guitar model in solidworks then imported the stl into vectric v-carve. As a more seasoned vectric user may realize, the model was imported with very rough vertical edges, ie the edge faces of the guitar are rough.

How is this dealt with? Will I have to draw a vector around the 3d model for the vertical cuts or is there another trick to this?

A couple of techniques. The one that will probably give you the best results is, yes, to generate a vector around the part and use that to run a profile toolpath to cut it to size. Make sure you node edit the vector so it's smooth and eliminate all unnecessary nodes. You might want to make the model very slightly larger to make sure the profile path cuts away all the roughness. Alternatively, you might add a zero plane, with its height set so it's right at the bottom of the profile of the top of the guitar. This will prevent the carving path from going down the sides of the guitar at all (much safer for your carving bit), and then use the profile path to cut it out.

Another technique is to add draft to the model. This may or may not help depending on how bad the edges are currently - it may preserve the roughness as grooves down the side. It will also make the edges come down at an angle and will increase the size of the part.

Start out by setting up your workspace as small as possible, and using the highest resolution (you need to hold shift as you open a new file, and it gives you options for 3 higher resolutions than you can normally get).

Then follow the advice above.

Is this advice with respect to solidworks or vcarve?

edit: you meant solidworks yeah that worked to smooth things out a bit more

When you export the stl from Solidworks be sure to set the number of triangles, sometimes called facets, to as high as reasonably possible to get the smoothest surfaces.

I did this previously and the model looks better, but its just not smooth enough for an efficient workflow. I've been giving fusion 360 a try, so we'll see how that goes.
