Confining a pipe within a hole

Confining a pipe within a hole

Confining a pipe within a hole

(OP)
Hey I have to model a pipe within a hole for one of my projects.  I am kind of new to SolidWorks (only started using it on 5/25) and I cannot find anything to confine a cylinder within another cylinder while still allowing free movement in all directions.  I have tried the advanced mate confining it to the minimum and maximum distances, but when you move the pipe too fast, it just comes outside the hole and wont go back inside until I quickly move it inside the hole again.  I would like something that will permanently keep the pipe within the hole.

A concentric mate is not working for you?

A concentric mate will only  match the centers of the two circles so it will not allow for movement.  I need it to act like a pipe within a hole in real life - it needs to be able to move in all 3 directions and be able to tilt while in the hole.

RE: Confining a pipe within a hole

I understand now.  You should try to create an axis in one part, and then a sketch point in the other (centered in the diameter), then mate the axis and point as a Coincident Mate.

That will get you mostly what you're looking for.  You might also look into the Move command with Physical Dynamics selected.  Of course it depends on what you're after.

Hey, thanks for that.  I don't know how to actually create an axis within each part file, or how to mate to an axis for that matter, but I did create a centerline through the pipe.  I then mated the midpoint of the centerline (it wouldn't let me select the centerline which I was planning to use as an axis) to the origin of the hole so it moves perfectly in every direction.

I have another problem that I am working on right now, so if I can't find the answer to it by the weekend, I will post it up.

thank you madmango and eltron (by the way, I looked into the move with physical dynamics and it wasn't what I wanted)

(used 2006)

Try this; put a cylindrical hole in a Plate.

Make a Sphere with OD that matches the hole diameter of plate. Insert an Axis using Front and Right Planes.

Extrude-cut a hole through the sphere that will be some dimension larger than the pipe.  (Your "free movement"
Make a Pipe, and Insert an Axis using the Front and Right Planes.

Make an Assembly with Plate matched to origin.

Insert Sphere with its Origin mated to the Top Plane of Plate.

Mate the OD of the Sphere to the ID of the Plate Hole

Insert Pipe.  Mate-Parallel Top Plane of Pipe to Top Plane of Sphere. (although not necessary, a Limit Mate can be used here too to keep it somewhat restrained vertically)

Mate>Advanced>Limit Axis of Pipe to Axis of Sphere with the Upper Limit set to ((ID of Hole in Sphere - Pipe OD) / 2)

Pipe should be able to be moved all around, but wall of Pipe should never go outside of the Sphere's ID.

In this example, a Pipe of 1.050" OD was placed in a Sphere that has an ID of 1.750".  The Limit was set to 0.350"

Zip the pictures first.

Or just cut and paste the link when it come up in the upload dialog.  It won't have cute box with the paperclip, but it will have the link.

Danadcorps,
Have you had SW training? I strongly suggest it.
YouTube also has a lot of 'how to' videos.

I have personally had no training whatsoever except for the 10 minutes where my friend showed me how to extrude, cut, loft, revolve, and use sheet metal.  I'm an intern at my office so I'm pretty much learning everything on-the-fly by experimentation, asking questions here, asking questions of my superiors (one of which is the friend who gave me the 10 minute intro), and watching youtube vids.  I am enjoying the program a lot.  

The advanced mate using the axis was a great help (when I told me friend, he was like "oh yeah...i should have told you that you could do that").  I haven't had time yet to try using the sphere, but if i get a chance I'll give it a go.
