Convex surface

andrew_morris929

Hi,
New to onShape, and enjoying it so far, but I have a question which may be really easy

Is the an easy way to apply a convex surface onto on side of a cube for example?
I'm trying to reproduce a panel that's about 5mm thick, with a slight convex surface, about 2mm deep.

I though maybe of somehow intersecting a rectangular block with a large sphere, as that's how I'd do it in OpenSCAD, but is there a neater solution?

Thanks in advance

Cutting a rectangle out af a hollow sphere seems about right to me

Is the part in the document below what you're trying to achieve? - Scotty

that's another neat solution, thanks

YOU SAID —
... a convex surface onto on side of a CUBE. I'm trying to reproduce a panel that's about 5mm THICK, with a slight convex surface, about 2mm DEEP.

Little hard for me to interpret what you said above. I’m guessing you wanted a cube that was 5mm in all dimensions

And I’m guessing the 2mm was from the top to the bottom of the curve.

Anyway here’s what I came up with — it’s just one more way of doing it

By the way, the last feature — REVOLVE — was set to REMOVE

Here’s a way that is more along the lines of what you and @john_mcclary mentioned above

When doing the Extrude — Intersection was used

I was thinking he wanted a shape like this

I stand corrected

Like I said in my first post, I did see where he said SLIGHT, but it’s hard for me to interpret what he meant by the 2mm and the 5mm dimensions

And where the CUBE came into play ?

@john_mcclary

Yeah I think you’re right John. Because I went back and read it again and it said PANEL

AND this time I took your lead and incorporated SLIGHT
