If you did not complete the last section, download and open the farnsworth01.axm file from the FormIt Primer folder
Make sure that you're in the 3D Perspective view by clicking the 3D cube in the Navigation bar
Group the rectangle in order to prevent new geometry from "sticking" to it. Double click the rectangle to select it. Right-click and choose Group (G)
You are ready to start sketching out the upper terrace of the Farnsworth house. Click here to learn more about 3D sketching with World Axes. Now let's start by creating a rectangle on the imported image
Click Settings > turn off Snap to Grid (S G)
While in the Line tool, click near the upper left corner of the upper terrace in the imported sketch
Move your mouse along the red axis that appears. Click the Tab key to input the exact dimension. Make the long side 77'-4 1\8"
Move your mouse down along the green axis to define the short edge of the upper terrace. Set the dimension of the short side 28'-8"
To define the other edge of the rectangle, move your mouse along the red axis and hold down the Shift key. The red axis line with thicken to indicate that the line is locked to this axis
Note: The red and green axes keep you parallel and perpendicular to the grid. When you draw a line off of the world axes, a purple axis line will allow you to stay 90 degrees relative to your off axis line
While the Shift key is pressed - move your mouse to the first point you drew. Click to commit the end point.
Release the Shift key and click the first point you drew to finish enclosing the rectangle. Press Esc twice to clear the sketch tool
Single click inside the outline you just drew to select the face. You are automatically in the drag face tool
Single click to start the drag face operation. Move your mouse away from the face to drag in that direction. Hit Tab and input 12'-2", then hit Enter. You've created a mass!
The following exercise is not critical to finishing the house. It will allow you to experiment with some of the other 3D Sketching tools.
Select the Arc tool. Click to define the start, and then the end point. The third click defines the radius of the circle that defines the arc
Select the Spline Tool. Click to define any number of points to draw a spline
Select the Circle Tool. Hover and Click to define the center point of the circle. Click and drag to define the radius of the circle.
Note: When you draw a curve that intersects with other points, curves, and solids, the objects may be jointed into one object. To avoid this, we will use Groups in a later exercise to isolate geometry.
