Artcam Express 2015 no mod's

I'm new to Artcam express 2015

after owning this software for two years I thought it time to use it. However now artcam has been bought by AutoCAD and they really just point you to there free software and after that it's pay per month.

What I would like to try and cut on my cnc is a length of quadrant with a length of 880mm x 68mm radius is there any one that could explain how I can design this on Artcam express 2015 with no mod's added as they are no longer available for send me a relief of the quadrant so I can make the tool paths my self.

The reason I want to cut this quadrant is for my Kitchen the old MDF corner quadrants have swollen and need replacing. I thought I could cut new one's out of beech as the worktops

hopefully yours
