Does anyone have any tips/tricks and or advice on how I could duplicate this shape (as close to the original d
imensions) in CC?
imensions) in CC?
Is that traced, or just drawn?
Do you know the radius or angle on the ends?
You could do this with math or with geometric construction. Either way you need at least one more dimension.
I would draw an 8" diameter circle, cut it in half to get your top arc and verticle dimension, and then a 10" rectangular box to meet the width and height of the desired flares. Then just run an arc from the corner of the box to the intersection of the box and circle.

It’s pretty straight-forward though — start by setting the overall dimensions in Job Setup:
then make a circle:
Then draw in another circle:
Adjusting their position/placement until things line up as desired:
Draw in geometry to use to divide things:
and then copy and paste the additional geometry:
and mirror it horizontally
and drag into alignment:
Draw additional geometry to define the ends:
Select everything:
and use Trim Vectors to remove what is not wanted:
if need be, zoom in:
Delete the unneeded lines:
Draw in a line for the bottom:
Select everything:
Join Vectors:
Yes

I traced it. what would be the other dimension?
This is incredible. I’ve have to bookmark and save this. Thanks!
Either this angle, or this radius…
If it’s traced from an original part that you are duplicating, I think your best bet would be to straighten out the image so it’s square, then import it as the background image & draw the vectors over it.
It looks like the angle on the right end is steeper than the left.
Will drew his version with an angle of 0.0, but the construction techniques will be the same.
If you adjust the image to your dimensions, the background looks like this, with a centered 8" circle
It doesn’t look like I have the trace option. It’s been a while since I’ve updated, I’m on V6. Does this mean I have purchase the update at this point? This may be the reason to do so.
To trace manually & match the image as closely as possible…
Here is the adjusted image, rotated so the bottom is flat & scaled to 4 x 10.
Bring this in using the Background Image, 0.183 scale, 1.000 Opacity, and align it with the workpiece
Create the large circle at 4" radius, then adjust to fit. I ended up with a 3.75 radius, and the center at X5.125 Y0.250
Draw in the ends using create curve. I just draw a straight line from the corner to the tangent point on the larger arc, then adjust the curvature using Edit Nodes. Click on Edit Nodes, select one of the end points, hit the “S” key twice to toggle smooth so you see the handles. Adjust the handles to fit the curve.
Do the same at the other end. Then connect them up into a contiguous (closed) shape. Join the curves
Create a large rectangle to subtract from the circle…
Select the circle first, then the rectangle, then Boolean Subtract
Now select the closed shape with the end radii, and Boolean Weld or Union
Voila!!
