Mmmmmmmmmmmmmkay........I seem to be unable to do an extrude cut up to a cylindrical surface. I seem to remember this working in the past?

It's the hexagon pictured below: it needs to cut through the boss and not through the cylinder. If I choose up to next, it goes through the wall of the cylinder. If I choose up to surface and select the cylindrical surface, it goes through the cylinder to the far wall. I've attached an image for clarity.

Anyone have a clue they could share with me? Greatly appreciate it!

Hello Kris,

Have you tried "Up to Body" and select the cylinder?

  Up to body cuts through the whole cylinder.
  
  The cylinder is a hollow revolved boss. Can't supress the hole.

    So I am not seeing a cross hole in the side of your cylinder? What is that feature that looks like it crosses the edge of your hexagon? Curious to what I am seeing there.

      Oh, that hole. I added the hexagon before I added that slot, and it still would not fucntion properly. Even if I roll back and re-do the feature, it doesn't cooperate.

    are these two parts in an assem or multiple bodies in a part?
    
    does the cube already have the circular face on the bottom of it where it meets the cyclinder?
    
    if it does, select that face instead of the cylinders face and it should work for the up to surface.
    
    if its its own part up to next should work for that. hard to tell without having the file...but thats what it looks like to me.
    
    or make the circular cut from the side face, convert the circular edge of the cylinder and cut the body of the cube only.

    Also the thing with a full 360 surface face it never seems to work, if the face was broken aka split it would work fine.

      All one part, Lenny. The cube does have the circular face but there is no way to select it, as it's flush with the cylinder. I even tried "select other" with no success.

Think that hole in the cylinder may be the issue. Can you suppress and then try?

Cheer,

here you go - I edited the boss and unmerged it from the cylinder, changed the cut to up to next, and added the combine feature after the cut.

Thanks Jeremy......can you step me through how to unmerge the boss and do the combine? I've continued to work on this part and have more features on it, plus I want to learn how it's done for future modeling.

  Jeremy,
  
  When I unmerge the boss, it breaks the boss cut out because its got nothing to cut through.

Kris,

go to the help file and look at multiple bodies or do the tutorial Multibody Parts.

one of the most powerful features to use in SW along with convert entity tool in sketching.

Multibody Overview

Part documents can contain multiple solid bodies. For example, when you design a spoked wheel, you know the requirements of the rim and the axle. However, you do not know how to design the spoke. With multibody parts, you can create the rim and axle, then create the spoke to connect the bodies.

You can manipulate multibody solids the same ways you manipulate single solid bodies. For example, you can add and modify features, and change the names and colors of each solid body.

A folder named Solid Bodies appears in the FeatureManager design tree when there are solid bodies in a single part document. The number of solid bodies in the part document is displayed in parentheses next to the Solid Bodies folder . You can organize and manage solid bodies in the following ways:

Group bodies into folders in the Solid Bodies folder .
Select commands to apply to all bodies within a folder.
List features that belong to each body.

You can create multiple solid bodies from a single feature with the following commands:

Extrude boss and cut (including thin features)
Revolve boss and cut (including thin features)
Sweep boss and cut (including thin features)
Surface cut
Boss and cut thicken
Cavity

Modeling techniques that you can use in a multibody environment include the following:
