Rule Failure Details:
 Minimum Radius at Base of Boss
 Definition: A fillet of a certain minimum radius value should be provided at the base of boss to reduce stress. Also, the radius at the base
of boss should not exceed a maximum value to avoid thick sections.

 Minimum Draft Angle
 Definition: Draft angles should be provided on the inside and outside of part walls in the direction of draw. A draft of 0.5 per side is
minimum requirement in most cases, although a larger angle will make it easier for part release.Properly designed draft angles will greatly
assist in part ejection from the mold, reduce cycle time, and improve productivity. Textured surfaces need additional draft to easily release
the part, and eliminate drag marks or scuffing of the part surface.

 Recommended Rib Parameters
 Definition: On a plastic part, ribs are added as protrusions along the length. Ribs can serve a number of purposes. They can add
strength to a part or act as a decorative feature to a part design. A rib can also minimize warpage in a part. Ribs need to be designed in
correct proportion to avoid defects and provide the required strength. Thick and taller ribs can cause sink marks and filling problems
respectively. If ribs are too long or too wide, strengthening ribs may be required.

 Mold Wall Thickness
 Definition: Mold wall thickness gets affected due to spacing between various features in the plastic model. If features like ribs, bosses
are placed close to each other or the walls of the parts, thin areas are created which can be hard to cool and can affect quality. If the mold
wall is too thin, it is also difficult to manufacture and can also result in a lower life for the mold due to problems like hot blade creation and
differential cooling.

 Undercut Detection
 Definition: Undercuts on a part should generally be avoided. Undercuts typically require additional mechanisms just adding to mold cost
and complexity. In addition, the part must have room to flex and deform. Clever part design or minor design concessions often can
eliminate complex mechanisms for undercuts.
