Design Rules

In addition to the following rules, see the material-specific limits.

Profile Cannot Intersect Itself	BAD	GOOD	Reason: Unrealistic Geometry
Profile Cannot Have Hollow Sections	BAD	GOOD	Reason: Our manufacturing is subtractive only; we cannot machine areas with no access.
Profile Cannot Cross the Revolution Axis	BAD	GOOD	Reason: Unrealistic Geometry
Profile Must Enclose an Area	BAD	GOOD	Reason: Unrealistic Geometry
No Inner Diameter Grooves or Undercuts (this includes backside chamfers)	BAD	GOOD	Reason: Requires specialized tooling and not yet automated.
No Face Grooves	BAD	GOOD	Reason: Not yet automated.
No Overhangs on the Outer Surface	BAD	GOOD	Reason: Not yet automated. Some overhang designs are impossible to reach.
No Blind Cone Points	BAD	GOOD	Reason: Each unique cone angle would require a custom tool.
