There is something like _OffsetFace for Solids?

Hi all! Wanted to share with you a question here. Maybe someone has the answer.

I work with 3d prints and all the time I must do the tolerances in a manual way when I must join pieces after printing.

Long story short, I must do some curves, offsets and finally some booleans to achieve that tolerance needed for assembly. Saw in Fusion360 something called OffsetFace, where you select the faces, put a value and it’s done. There is something similar in Rhino?

Thanks in advance,
L

Hi Luis - there is OffsetSrf, Shell, OffsetMesh - se if one of those does what you like.

Hi Pascal,

Thanks for the answer. I use a lot OffsetSrf and Shell. I was looking for something more like the OffsetFace command in F360. Check out this to understand the main idea: Fusion 360 Help

Of course the examples are the worst (for the first one we could use MoveFace or just the Gumball; now, the power of this tool is that you can select more than one surface in the solid (like for example, the exterior perimeter in the third example) and give it a dimension instead of creating some curves for extrusions and doing some booleans to create tolerances between pieces. I know it’s possible in Rhino, but you need some work before which is repetitive and constant in my case.

Maybe is not possible something like this at the moment, but for sure could be useful for future releases. I have been using Rhino for ten years or more and I’m always thinking on ways to improve my main tool.

See you around,

You can do also MoveUVN and move control points of the surface to do offset. I know it`s still not the same as you want. I would love to see a feature like this in Rhino. As far I know it’s needed to do that manually on each surface which is a lot of work to do. I hope I’m wrong.

Hi Luis - please post a simple example 3dm file showing the starting point and desired result, at least roughly.

Ey Pascal,

Sure. Attached you will find a very simple example where you can check what I’m trying to say.

Cheers,

Hi Luis - the simplest workaround would be:

ExtractSrf Copy=Yes, crossing window select vertical faces from a side view
Join
OffsetSrf Solid=No Corners=Round

It is probably possible to automate this at least somewhat.
