Hello,

How can I create a solid to clog the hole in the ellipsoidal object, as in the attached file?
I made the two shapes based on the geometry of the object cross-sections but creating this closure is beyond me.
This item is part of a bigger thing and I can't do it all over again.
The hole was constructed with a Boolean operation and then the customer changed his mind.
Soon I have to send it all to the guys who will make the acrylic model.

Thanks,
Marky

Marky,
to just do a patch.
copy the two lines from the solid.
do a blend on both of them then cut them in half.
copy the hole circle edges so they are lines as well. do a rail revolve with the half bend lines and the corresponding circles.
remove the inner surface wall to the solid and then boolean the two surfaces you made to the dome shape (or join them)

hi Val2

Great job
can you do a gif or a vid tho explain ?


improvement; after your job,
you can hide lines

Untrim the surfaces to delete a hole.

Wow!

Magic!

Thanks a lot.

Burrman,
while yours is the preferred and more elegant method I have run into situations where in some cases causes more problems that then need fixing. Patching locally keeps problems local.
Val

hi BurrMan

Many thanks
it works fine

Détail :

1 - Select Pomarańczowy surface
2 - Delete Pomarańczowy surface
3 - Select Joint srf
4 - Separate Joint srf to obtain 6 surfaces
5 - Select 26 Edges
6 - Delete 26 Edges
7 - Select 6 Surfaces
8 - Joint to make a solid

 

but i dont understand why deleting 26 edges erase the hole on the surfaces ?

here a gif

Hi Chri,

""""""but i dont understand why deleting 26 edges erase the hole on the surfaces ?

This is untrimming a trimmed surface.

So things like that hole are represented by a trim boundary that has a type of label that says "hide inside"... the actual surface doesn't really leave.

MoI has a mechanism for untrimmimg a trimmed surface. That is done by selecting all the trim boundaries and deleting them to reveal the underlying surface.

In some cases you may want to copy and save the trim boundaries before untrimming. So if you need to retrim a particular part, you already have the boundary for the surface.

Hi Val,
Sometimes untrimming a surface can reveal parts of the underlying surface you wanted to remain trimmed.

Copying the trim boundaries first and keeping those, will allow you to retrim parts easily.

I think Michael has spoken about upgrading the untrimming command to allow a user interface or just more power to untrim only specified areas, without the need to untrim an entire, separated surface.

Burrman,

that will be nice.

HI

If i understand
We could say that when we are creating an hole, this hole is just an hidden part .

and sometime peripheral contour can reveal the limit

Hi Christian,
""""""""""""If i understand

Sure! Here is a little doodling with trim boundries and untrimming and retrimming them. Note showing points reveals the underlying surface still there. The "trims" are just "hide this part and hide this part" of a NURBS surface.

Thanks BurrMan

not so simple.
