Cutting path questions

That depends on what exactly their software expects. I'm not familiar with it.
Generally, closed polylines work best, but it varies with different CAM software.

A good drawing program like Coreldraw or Adobe Illustrator, or even better Aspire . Enter in node editing mode and make sure all lines a joined properly at the corners.

below is a sample when you magnify a problem. Third pictures looks ok but could be problematic if you have not joined the lines:

Hi thanks for the picture, yes you're exactly right when I magnify the corner in the cam software I get a corner which is over shot on both lines like your first picture. The test shape I cut was done just using the basic line tool and not a polyline so I think this is the first thing to try.
im going to stick with autocad for now cos it's what I'm used to and cos I have it I obviously tried sketch up but I don't find it that good for drawing tbh we only use SketchUp to take a 2D autocad view and render it in 3D for clients approval.

No problem. When i see the toolpath simulation doing crazy stuff like digging a grave there, i know its some open line or edge left there

Chris Do you have "object snap" clicked ( F3 on mine) there are settings that you can snap to end of line or centre point etc.

I do when I use autocad yes but am unsure on whether or not it is set to default on sketch up?

If you have Autocad why use sketchup
