Hello, I would like to know

 ![6A7B76B7-0D4E-45A8-86D4-3F3F310C8802](https://us1.discourse-cdn.com/flex002/uploads/shapr3d/original/3X/0/3/03e4aad6e36a59d6c404bf35008928ae5d054d4a.jpeg)  
how I can join two hollow tubes together so they will be able to be taken apart and put back together.  
What kind of joint can I create and how to do it?  
How best can I create either a small screw together joint or another type of snap fit joint.

Thank you for your assistance.

A lap joint is the best method for aligning and joining two tubes. Assuming the tubes are rigid, I would use a bayonet design to lock and unlock the two tubes. Here’s a Q&D approach.

Very nice, which command takes the sketch of the “L” shape and projects it to match the inside curve of the tube?
