Help: rounded corners on single polygon

[maruska]

Is there an easy way to create a single n-sided polygon and then round the corners of it to a specific radius?

The attached image shows the effect that I'm going after. Start with a polygon, add radii the corners.

What I did to actually get this was: create the polygon, extrude it up into a volume, select the vertical edges of the extrude, apply an edge bevel, then select all the vertical faces and the top face and delete them leaving me with just the original face, but with radii.

I'd rather just create a poly, select the verts, add a radius.

I'll be doing this a lot - it's for a city mapping project and I don't think Nurbs curves are the right way to go here.

Ideas?

I tried in 2015 with select the 4 border vertices and EditMesh>Chamfer "delete face" on but unfortunately i may have a bug because is not letting me chance the subdivisions in the channel box, if you enter 3 for example it doesn't let me....stays at 1.

Let me know if your does the same.

Yeah - I get a similar result. Vertex Bevel locks-out several of the channel box options, and even if you manually unlock them to override the values, you get wonky results (which is probably why they are locked).

I just tried in 2016 and unlocked the attributes but the result is laughable...don't know why it doesn't work the way it should...and even the result you get doesn't  seem to have a practical use.

You might need to build one shape then duplicate and adjust it with some deforrming tools I guess.

Thanks - I'll keep poking around - but my extrude and delete method works as a stopgap approach.

Hi,

Thank you for posting to the Area forums. I think you have figured out the most efficient way of doing it with the extrude and delete. I noticed that smoothing with Keep Border turned of has a similar affect, but makes it harder to control the radius and you have a lot more polygons.

Cheers,
