Trying to cut this out but not getting correct rendering. What am I doing wrong? Any help appreciated.

What angles do you need?
Would it be possible to use a V tool to just directly make the cut?
Say, the larger faces are cut with a 90 degree tool, while the narrower ones are cut with a 60?
Draw up the tools in profile:
Then measure the width necessary to cut to:
Then draw up a cut that wide:
and select the outline:
and make a cut to that depth:
Then, do the same cut for the 90 degree face:
Draw up geometry which gets a line at that distance:
and position a line on it:
Then rotate it:
drag it into registration:
and use a Circular Array to duplicate as necessary:
Clean up and select the open vectors:
and assign a toolpath using a tool to the desired depth:
which mostly works — except that the angles don’t line up at the same depth — experimenting with this to arrive at a workable solution is left as an exercise for the reader (or until later this evening when I have more time).

Thanks you’re quick to responds! That’s what I tried first but it wouldn’t line up (same as yours) so thought I’d try the modeling tool.
Will keep playing :).
You’re missing at least 1 dimension. Either one of the angles, or the diameter of the top octagon.
If the base is 110mm, the top looks to be about 90mm. (time to do some math 
)

Left is on CNC and right is what I’m trying I achieve made with jig on table saw. Want to go deeper (50mm height/bevel 25mm).
Make sense?
Actually, if one cuts away the surround:
Then this seems to be what is wanted:
The tablesaw version with vertical sides would be even easier.
That said, you probably want to model this sort of thing in a full-fledge 3D program such as:

Almost. The one on the right kinda looks like the bottom faces are vertical, but looking at the right side they look like they are back-drafted. ???
This is different than the original drawing you show, in which the sides are triangles.
What is the 25mm you mention? If the stock is 50mm thick, then the sides all look like they are greater than 25mm tall. i.e. the peaks of each side face go past the half-height because they overlap.
If you can define with dimensions what you want, someone can show you how to build it.

Yes - bottom faces are just the hexagon cutout starting from top face to the bottom. Top faces I was trying to start at the top, then angle triangles halfway down (25mm as base is 50mm high/thick) using the modeling tool in carbide create pro - but I know it’s only a “artisan drafting tool”.
First time using it, so just seeing how I can create something simple like this. Didn’t end up being simple 
I have it modeled in fusion but was trying to see if I can get it done in CCpro. I use it to model my ideas but get lost when trying to figure out how to machine the pieces.
If you have it in Fusion, why not export an STL and then import that? (or learn how to do toolpaths in Fusion — it’s supposed to be quite good at that)
I am still learning the machine - learning with baby steps in my off time. Bought ccpro as it’s so simple with the shapeoko. Hopefully once I gain more confidence in how machine works with different bits (few months), I’ll start using fusion more 
See:
If you’re still stuck, upload the STL and we will walk through this with you.
OK, so if I cut a section through the yellow line it looks like the yellow side view/section above.
What is either the angle of the side from the top octagon, or the width of the top octagon? Or even better, both dimensions.
Admittedly, I tried to model the version I guessed at above (90mm top octagon with triangle sides), and I had to fudge the calculated angles to get close to the correct shape.
With the octagons 110mm and 90mm and a height of 50mm, the angles work out to 7.17° and 16.206°. (In CC, you need the reciprocal of those angles. 90 - angle)
