This document provides a procedure for defining a user-defined feature for holes on molded parts using computer-aided design and engineering practices. The procedure involves accessing a ready-made hole template, creating a uniform part design and positioning the work coordinate system at the beginning of the template lines. It also includes selecting a part mold type from the library, customizing the design, and saving it once complete. Following this procedure will help standardize hole features and ensure correct mathematical data.

USER-DEFINED FEATURE FOR HOLES
Introduction: Following is the procedure to define a standard common
method to access and apply a User Defined Feature (UDF)
for holes on molded parts. This course of action will help
users to understand and improve upon the design and build
aspects of parts and assemblies using the latest computer-
aided design and engineering practices.

ACTION
1. Access a ready-made hole template located on the (L:)
Drive, Library Folder, Templates.
Note: A sample three-dimensional hole outlining a
standard format where to cut and carve out from a given
solid object is shown. The over-all hole architectural depth
and spatial geometry view is represented on the blue-
coded “Material Input” “X”- direction of the axis and the
“Manufacturing Output” is denoted on the red-coded “Y”-
direction of the axis. Correspondingly, the “P” direction of
the axis will be the “Push” cut path and the “U” direction of
the axis will be the “Pull” mold side wall to carve out
portion of the solid. The point at which all four lines (X, Y,
P, and U) meet will be the line intersection where the
actual design sketch is to be placed. If followed exactly,
correct math data will be ensured.
2. Create a complete uniform part design.
3. Position the Work Coordinate System (WCS) at the
beginning of the line at “Absolute 0” with the “P”
direction of the line perpendicular to the “U” direction of
the line.
4. Select the Part Mold “Type” from the Library List located
under the Category menu option.
5. Choose Create, Arrange, and Customize from the
Options menu to further modify the part design.
6. Select the Save Design button located under the
Finished Design window to save the part design once it
is completed.
