Surface attach to Solid ( Inventor Sculpt alternative)

tom_kulaga

Hi All,

I've got a cylinder solid, and I've created a surface using 3 lofts (blue). What I would like to do is fill the area in between the surface and solid, and attach to the solid. In Inventor I could use the "sculpt" command to do that, but in OS, I end up FILLing the back side of the surface, then that turns to a solid, and I need to trim that with the inside face of the cylinder, and then Union them. Is there a cleaner way to do it?

You can’t do it in one operation, but you can probably use Enclose (keep tools) then Boolean (union). For the enclose you might have to select the part and the surface from the Parts List (not the screen).

Post it (public) and the community will show you how!

Ahh oops how do I that?

@tom_kulaga - Very easy - just hit the 'share' button and then select the 'public' tab and then the 'public' button.
Next copy the URL to the Part Studio and paste it here. The good people of this community love 'fixing' stuff

Here you go. I've made a simple example. I'd like to fill the area between the surface and the hollowed cylinder in the document.

Can Inventor fix this example? The surface doesn’t touch the cylinder all the way along and the ends are open. It would be several operations to do this. It would also be easier if the hole in the cylinder was cut out last. 

Thicken the surface, use Replace Face to fix the ends and Replace Face to make the thickened part of the surface match the inside of the cylinder. Then Boolean. Does it matter if it’s more than 1 feature?

Thanks for the reply.

I've got a better example here:

I've attached how inventor handles it.

The surface protrude a little into the cylinder, but it finds the area enclosed by the surfaces and the outside wall of the cylinder. What would be a neat way to do this in OS?

You could also shell the cylinder before doing the enclosure

OK the below GIF is right in line with your last post. I started with a pipe or tube and three surface objects.

I used Enclose to make a solid part.

Then I did a Boolean

Notice how the surfaces that protruded into the pipe were eliminated upon doing the Enclose

Thanks very much! exactly what i wanted
