+A FreeCAD workbench for creating CNC (or laser) constructions. It uses Assembly4 to mark locations for tabs or fingers.
+
+# Wish list
+* Basic functionality!
+* LCS/Axis creates tab/finger at that location
+* Planes create linear array along interface
+* Sketch to define custom tab/slot profile
+* automatic supports/angle attachments
+
+## Data
+
+### All
+* sketch
+
+### Linear
+* count
+* end offsets ?
+
+# Profile Sketch, automatic width/depth matching
+It would be nice if the profile Sketch can be variable in order to automatically handle different
+stock depths. The Profile would need a common definition, likely start at origin (0,0,0) with one
+line traveling +X and another in -Z. These line could be either; unconstrained, allowing the WB to
+set their length and have the rest of the sketch constrained non-numerically. Use a ratio based
+pseudo-unit; 1(ignoring mm) would take the exact thickness of the attached part, 0.5 would be half.
+All constraints in the model would be scaled to real world units based on these percents.
+
+# Automatic angle attachments
+In cases where two parts are not attached perpendicular to one another an angled attachment piece
+would be required. In some cases this should be able to be created automatically.
