After construction, 3 measurements will be taken. If you enter the values below carefully and don't (M)ove or (P)ush/Pull things out of place (Ctrl-Z is our best friend), then those 3 values will be accurate. Nothing short of perfect will do!

In which we join two rectangles, pull the resulting shape into 3D space along the Z (blue) axis and raise the roof by carefully moving two precisely placed lines.

In which we use the offset tool on the bottom of our house to push up a roof overhang. At that point we review the measurements that will be graded before continuing.

In which we offset 3 sides of a rectangle to pull out a door frame, then use a section of it to make bottom trim around the entire house with the Follow-Me tool.

In which we move a copy of the front wall, group it, then use it to start on a detailed window with 4 panes of glass by offsetting and dividing up an offset rectangle.

In which we use the offset and push/pull tools to continue the creation of a detailed 3D version of our 4-pane window, then select and turn it into a Component (NOT a group!).

In which rotate a copy of our window to put on another wall, then move several copies of those windows into place. We used to use a "Flip" technique for windows on opposing walls but a Blender update means now we just rotate it 180°. I cut that part out. We use scaling to make a variety of sizes, too.

Using other parts of a model to decide where to click as you create is incredibly useful. It takes some practice, but releasing the button in between clicks enables you to be accurate without sacrificing time.
