Hi

Can anyone please let me know how to add spherical radius of 10.62” to the edge of the part that is
marked in green.

Thank you,

Andy

With the Fillet tool?  It's difficult to say more without more information.  (See Can someone help me with my school assignment?.  Even if you aren't a student the information there still applies.)

Nope - filet tool don't work in this case. Radius is part of the sphere that is 21.25" in diameter - R 10.625

If the fillet tool don't work then it don't work.  What sphere?

I am a student and not looking for someone to do my work

Ok, so you want a spherical radius at the corner that you've chamfered.

First, delete the chamfer. Next make a fillet feature and select each of the 3 edges that intersect at that corner and assign the same radius to each edge.

The size of the radius that's possible will be dependent on the size of your block.

The corner where the fillets intersect is spherical. No special tools needed, it's just what happens when 3 fillets of the same radius intersect at a corner.

Radius need to be 10.625” not 0.5” I wouldn’t ask if it was
so simple.

Oh, it came up as magenta on my screen.  That should be even easier to do, same general methods might work.  Three points of contact should work.

Do you try to make it as this one?

Can you visualize what you are talking about? You can't add a "spherical radius" to an edge. You've got to put the question in some sort of context. It sounds like you don't have any idea what you're doing.

Has your instructor covered the Revolve tool?

Can you Attach the *.sldprt file of your attempt here?

Did you by any chance mean Vertex rather than Edge?

First, the only green I see is a dimension.

Secondly, how would you turn any of these edges into a sphere?

This the  problem.
DRAWING calls for radius in this area and I don’t know how to do it. I just
need someone to point me in the right direction. I am not looking for someone
to do my job. I am not solid works expert like you guys that’s why I asked for
help. But I see that most of you are just sarcastic. Thanks anyway.

Hello,

I don't believe there's much sarcasm here, but I do think words are being misapplied and misinterpreted.

For example, do you really mean "spherical"? Or do you just want fillets on the face?

I'm sorry you didn't appreciate the sarcasm.  We're trying to help, but when you talk about a sphere and post a picture of a body with all flat sides we have trouble figuring out to do that.

I'd suggest you model a sphere with that radius, make the three vertices of that angled surface coincident with the sphere surface (from inside), then hack away the parts of the sphere you don't want.  You'll still have a problem with your magenta corner you knocked off.

Why don't you just start with a sphere and, using offset planes or whatever, chop away what you don't need?

Hello Andy,.. are you trying to do something like this?...

Thanks for your help. Radius needs to be in one area only. I
marked the area – it is the intersection of the 3 edges – vortex. I think I am
on the right track now. I see that I need to start with the sphere and just cut
off what I don’t need - just like James suggested.

Thank you

Andy,.. maybe something like Todd Blacksher  just posted?... (I'll add another set of options,.. using different SetBack radius and a Fill Surface/Surface Cut... image attached.)

Sometime on drawings notes you see some notes as....free of burrs or sharpen corners

Andy,

It is hard to tell, but it sounds as though this is what you are looking for -

It is a lot easier for us to help if you can upload your model so that we can see what you  have already attempted, as well as providing more dimensional information.

If this is what you are after, you can just model the initial shape, then make a surface model of a sphere, and use it to cut the block using the Cut with Surface command.

The best way to think of it is wrapping a basketball around a block, and using the basketball to cut away anything that is sticking out.

todd

I was thinking same as you Todd....

Todd you are unbelievable – basketball around a block. I
would never think of that.

Thanks so much

That's exactly what I was trying to explain although not nearly as eloquently.

Guys

I really appreciate everybody’s help. I am sorry that I was
not clear describing the problem. I just wanted to mark the “problematic area”
so I put the chamfer there. Sorry for the confusion.

Andy Pietrzykowski - I can only speak for myself here but I am fairly certain there are a bunch more like me on the forums, I'm a grumpy old man and sometimes I'll just make an off-hand comment meant as a joke but it comes off like a 'slam'.  It's all part of the 'good ole' days' when the new engineer would get picked on by all the old (experienced) guys.

Kevin

On top of everything I am not native English speaker – adds even
more confusion. I do mean spherical radius,  not just filets on the face. This entire area

That’s okay James – I will be a grumpy old man one day too – ha ha

Paul

I think this is it. I will try your method.

Thanks

..the other way,.. you construct a plane from the 3 points,. .and create a center/circle from the 3 points (and your Radius/Dome).. and create a revolve cut or surface cut.. (image attached)

I will try to see if this method is same as mine....maybe I need to learn a new one way....
