To "stretch" a timber:
1) Place one end exactly where you want it.
2) Double-click the timber to "get inside" it. AKA change your context to that of the timber. AKA "edit" the timber.
3) Select the entire end of the timber that needs to be stretched. It is not enough to select just the joint. Use the select tool (space bar) to drag across the entire half of the timber to make sure you select not just the joint, but any other geometry that is part of the end of the timber itself.
4) Type "m" for move. Then "lock onto a rail", by hovering the mouse over a long edge of the timber, then press and hold the shift key (do not click your mouse yet). Now choose on a point on that same edge where the joint meets the timber and click on it (usually at the shoulder or housing line).
5) Keep holding the shift key, and move the mouse to the destination point and click again. Note that the timber "stretches", but stays in a straight line.
6) NEVER use the scale tool. It will distort the geometry.
When using the TF Rubies, never forget:
A timber is a component at the top level of the model. It is cannot be part of any other group or coponent. A tenon (or any joint) must be a sub-component of a timber.
