Page 15 - Sketching the Raised Panel - Continued
The end result of this pair of lines should look like the image below, and the status bar should report the sketch as being fully constrained (only while in sketch mode).
The reasoning behind the method used for creating this sketch this way will become apparent later, but for now, we need a bit more geometry to complete it.
As you should be able to see in the animation above, start by grabbing
the Line 
tool from the Draw Panel 
, and hover at the top of the small
vertical line until the green constraint dot appears, then click to begin
sketching. Sketch over to the right a short distance, making sure the
Vertical Constraint Glyph is present, and click to create the first segment.
Continue in the same direction, and again go a short distance, look for the
Glyph, and click to create the second segment. Now go up perpendicular to
the first two lines a short distance, look for the Glyph, and click to
create the third line, and again for the fourth line. Now move parallel to
the long bottom line towards the far end of same, and look for both the
vertical constraint glyph, and the dashed line down to the end of the bottom
line and click. The last line segment is to close the loop by going to the
end of the bottom line where you hover the cursor over it until you get the
green constraint dot and click. Right click and chose Done or hit Esc on
your keyboard to exit the command. Save the file.
The sketch should now look like the one above. Now we need to project a
point. Double click the Panel profile sketch in the browser to activate it,
then grab the Project Geometry 
tool from the Draw Panel
. Hover near the
point at the upper corner of the stile profile closest to you until it
highlights, then click to project the point into the current sketch. Now turn off
the visibility of the Stile Profiles sketch to better see the projected
geometry.
