Connecting a rectangle to a cylinder

[robazarcon]

Any tips on how I can make a smooth, aesthetically pleasing transition between the cylinder and the rectangular base? Is this a fillet/champfer solution?

In my head it would have the base of truncated pyramid but the top of a truncated cone—is that possible.

Hello - something like the attached file - is that more or less what you are after?

Yes! Would you mind showing/telling me how that is accomplished?

Hello - see the attached file - there are several ways to get there, this makes nice simple surfaces.

Thanks for sharing the step by step. Step 3 is just beyond my skillset right now with Rhino, but I’m learning fast (thanks to all the help on this message board).

I had a similar issue some time ago - maybe this is also helpful!

Network surface from circle to rectangle

Hey, I am trying something pretty simple: Creating a network surface consisting of 4 guide curves, a circle and a rectangle. However when I create the surface, it is not closed. I guess this is because of the combination of a circle with a rectangle… Are there any nicer solutions to this? Thanks a lot [network_srf%20] network_srf.3dm (204.4 KB)
