Assembly Concentricity Constraining

[Anonymous]

I am creating a cylindrical cage with a lid offset by 0.75". I created an L to join the lid and cage together. I have already mated the face of the L with the bottom face of the L but now that I am also trying to make the L flush with the inner face of the cage I am running into difficulties. Whenever I try to use Constrain or Joint, the L will either go to the center of the cage or conflict with the cage.

Additionally, if I try to pattern the L to create 3 additional L's around the cage, the radius of the circle is too large and the new L's will not fit inside of the cage.

Hi, do you need to achieve something like the following?
In the video inside the rar, I match the two axes of the cylindrical faces.
I hope this helps with your problem. Regards!

Hello Sergio,

Thank you for responding but it looks like the the cage and the L are still conflicting. I am trying to get the L flush with the inner face of the cage cylinder. If you look at my attached screenshot, I am trying to move the outer face of the L from the line on the left to the line on the right. For some reason the L keeps wanting to be flush with the outer face of the cage.

It happens that in your example you have two different radios in the parts. With the restriction its seeks to align the centers of each cylindrical face. The inner radius of the cylindrical face is 11,963 in and the outer radius of the L is 12,006 in.
Then you should modify the radius of one of the two parts to suit the position you need.
In the example of the video I will reduce the radius of the L, and place one separation of 0.05 in.

I hope the video is clarifying and can be useful. Cheers!

The outer radius of the L bracket needs to be the same as the inner radius of the cylinder cage.  Then an axial mate can be used to constrain the bracket to the inside of the cage.  Also, your sketches aren't fully constrained. See attached.

Thank you. Using your solution did work.

Thank you. This was the issue. I see now why it kept defaulting to the outer surface.
