I wish to extrude an octagonal shape onto a smaller rectangle.
How would I achieve this.
Obviously the diagonal sides of the octagon converge to each vertex of the rectangle.
I think I have attached a picture.
If you put radii on the corners of the rectangle, it can be done a lot easier. With radii, the number of entities match in the profiles, which makes it much more stable.
Use Loft boss or Boundary boss and have guide curves which link diagonal sides of the octagon to vertex of the rectangle.
Do what Maha says.
Select the end of the octagon and convert entities for your other sketch.
See Jeremy's reply below.
you can just select the face of the octagon for the profile - do not need to create another sketch.

Here is a thought - Attach your *.sldprt file here if you can't figure it out.
Something like this?
..or manually split the sketch to match the segments..
I do not like to split a sketch because it will become under defined. If I am correct I can remember in a YouTube example this also being used.
sure, I guess it could work.. we can guess how this transitions...?
Yes this is what i am looking for.
However the rectangle is smaller than the octagon.
What do you mean exactly?
Can you explain in terms of commands?
I got this.
Something is wrong but it is close.
I used lofted boss with sketches from the octagon diagonals to the rectangle vertices as GUIDE CURVES.
I have attached a screenshot
I have attached my .SLDPRT file.
Please see the screenshot below to see where I am at.

Back in a few minutes with the "solution"...
I used the LOFTED BOSS method with guide lines like Maha said.
Can't get the shape that I want (like the one you created but with smaller rectangle).
The extrusion is twisted, I can't get the diagonal sides of the octagon to converge with the rectangle vertex.
Think I have made a mistake with my guide curve sketches.
Thanks for helping

Before we go too far with this design - what are we designing? What is the completed Design Intent? Do you have an image of a real world equivalent?
It is where the tennis racket handle (octagon) meets the tennis racket head frame.
That model is exactly what I was looking for
Please could you explain how you achieved this model.
More specifically what sketches did you draw for the GUIDE CURVES?
I'm assuming you used lofted boss.
I still can't get the shape to converge precisely on the rectangle corners.
I have tried moving the connectors but they wont allow me to drag to the vertex.
I have now sorted the problem.
Just needed to drag the bue connectors - "no guide curves required"!
Thanks for your help
Who marked solution?
Let's see the solution file.
Attach the *.sldprt file here.
It is miracle. At a glance I answered this question. In fact I am not interested in this question because it is not a challenging one. My answer is not deserve to be marked as a correct one because I made very little effort other than a short answer above.

Uhmm, you might want to give it a try. I had more difficulty that I expected. I am curious to see what I was doing wrong - that made it so difficult in SolidWorks (as compared to Autodesk Inventor).
A tennis racket (and probably nothing in the real world) meets at a perfect vertex that you had in your original description.
That is why I started asking about Design Intent.
