To build a model:

STEP 1: Add an element

- see Model Editor ; Mechanism Editor ; Part-Editor

STEP 2: Open the element's dialog

- see How to open a dialog

STEP 3: Edit the element's parameters

- see How to edit a Parameter in a dialog

STEP 4: Close the Elements's Dialog

Do Steps 1 to 4, again, and again, ...

Close the dialog before you start a different command to add a new element.

Two dialog exceptions: Add Dimension dialog and Add Plane dialog open immediately when you do Add Dimension and Add Plane.
