To build a model:

STEP 1: Add an element

- see Model Editor ; Mechanism Editor ; Part-Editor

STEP 2: Open the element's dialog-box

- see How to open a Dialog-Box

STEP 3: Edit the element's parameters

- see How to edit a Parameter in a Dialog-Box

STEP 4: Close the dialog-box

Do Steps 1 to 4, again and again

Usually, close the dialog-box before you open a different dialog-box
