Downloaded and tried Sketchup last night and got hand of it pretty good so I downloaded TF Rubies from Clark website. Played around with it (experimenting). Tried to create component and it seems not to work so maybe I am doing something wrong?

I started new template, designed a post with tenon on top, picked arrow and pointed arrow at the post then double-click it to highlight the whole post, click on right button on mouse and highlight/click 'Make Component'. Screen pop up, type in name of component, clicked 'any' (Glue to) and then clicked 'create'. It show up on the component tool but when you close the program and re-launch it, the component is gone?

What am I doing wrong?? I am trying to develop my own library of my joinery style.
