OnClick changes

i would like to know how to make my own set of items in the one click extension. for instance if i have 5 different types of chairs and want to add them to one click so that if i choose a chair and click with interact tool that it automatically changes to the other saved chairs i preset in one click

It all depends on what changes. If it is size, or color, you can change priorities of components using the OnClick function. If it is something more in depth, like the actual geometry of the chair, you can place all the chairs into the DC and set them to hidden, then show each chair one at a time with OnClick.
