Face Rectangle

This example cuts a round-top lite through a 36″ wide door: a 22″ × 36″ FaceRectangle whose two top corners have radii of half its width, making a semicircle.

The Feature Group's structure:

• Rectangle Round Top Lite (FeatureGroup × 1)
  • Lite Cutout (FaceRectangle, Face)

The Feature Group

• Coordinate References: L (length) from the Top, W (width) from the Lock edge, and T (thickness) from the Hinge Pivot Face.
• Locations: one location, 6″ from the top. This is where the top of the lite starts.

Lite Cutout

The Lite Cutout is a FaceRectangle on the Face.

Property	Expression	Value	Why
WLocation	$Door.Width/2	18	Centers the lite across the door's width
LLocation	Length/2	24	Puts the top of the lite at the group's location: 6 + 36 / 2 = 24
DepthClosestToRef	$Door.Thickness	1.75	Cuts all the way through
DepthFurthestFromRef	0.0	0
Length	36	36	Height of the lite
Width	22	22	Width of the lite
Radius1, Radius3	Width/2	11	The two top corners, which together make the semicircle
Radius2, Radius4	0.25	0.25	The two bottom corners

Because the expressions use $Door.Width, Length, and Width, the lite stays centered with a true semicircular top if you change the door or lite size.
