Too many entities from .jpeg

I'm relatively new to mastercam but have been in the machining business for most of my professional career. I'm having an issue with a project I'm doing.

For info, I'm using MCAMx5. I have a project that required the use of a .jpeg image which I then translated to an outline using the Rast2Vec app. I previously cleaned up the image using photoshop to make the lines as defined and clear as possible. However, after inputting it to Mastercam, it renders the lines (which appear straight in the image) as a series of thousands of small arcs. Once I create a toolpath, it results in g code that's 30k-40k lines. I'm looking to cut down the number of lines significantly and am wondering if there is a way to either have Mastercam render the image in a matter that creates more straight lines, or generate a toolpath that consciously avoids the small arcs and whatnot.

Thanks.

I had to delete the toolpaths to make the file an acceptable size, but here it is. If you zoom in on the edges, you can see that instead of being straight lines or wider arcs, they are made up of thousands of small arcs.

Sorry no automatic way you will have to redraw the areas you want to be better. That said in 2019 there is refit spline that would convert a lot of that into a single spline. Verisurf has some free tools that would do a good job with that also, but nothing automatic both of those would still take some work. I would estimate about 4 hours and someone could have it all cleaned up.

I tried 2 of the chains and reduced the arc count by 1000 arcs using the Verisurf Free Tool Fit to Chain.

Another way to do it would be redraw with 3 point arcs and you could redraw a lot it really quick maybe less than 20 minutes.

This has been talked thru' once , but here it goes again.... There is a free software called Inkscape, which I have personally once used and got really good results, much better than 

with Rast2Vec .
