How can I blend a radius on the top of this surface ? - I have drawn an arc and attempted to use the follow-me tool to drag it around the top but that does not seem to work ? [Screenshot 2021-02-18 at 7.20.50 AM]

It’s usually easier to use FollowMe by preselecting the path before you start the FollowMe tool, then clicking the profile face you want to follow that path, which should be in the same context. What size is your model? SU doesn’t work well with very short edges. If you can upload your model, not …

I addition to what @john_mcclenahan noted about technique and size (which we can’t estimate from an image) you will have problems because the profile is not perpendicular to the starting segment of the arc you want it to follow. This situation will usually cause issues with the ends of the extrusio…

Thanks John; It’s small, all my projects will be small as I am using sketchup for re-engineering small parts. I have attached the model, all of the vertical ‘pillars’ need a compound blended radius on them. base-4A.skp (1.2 MB)

Is this what you are looking for? [Screen Shot 2021-02-17 at 6.56.01 PM]

Yes, that’s exactly what I am looking for, how did you do it ??

I’'m heading for bed - after midnight in UK - but you are in some of the best hands on the forum. Why does the middle column in your model not have an arc but just edges at the top, and unsoftened vertical faces?

@john_mcclenahan - well actually the top of all 3 pillars should be the same compound radius

Yes, it looks as if it ought to be. Just wondered how they got to be different. Easiest thing is probably to delete the old column, and redraw it properly.

What radius should they have? They are have different widths. [Screenshot - 2_17_2021 , 6_41_14 PM]

You really should be working at a larger size for this kind of stuff. Either scale up by 1000 and use meters as if they were millimeters or use “The Dave Method”.
