In Pro/ENGINEER, you can change the hole type using the ECAD_HOLE_TYPE parameter. Note that when you export the mechanical database, the value of this parameter is truncated to 10 characters plus an additional "M" if the string is longer than 9 characters. Areas According to the IDF Specification, the first and last coordinates of an area must be the same (see the BOARD OUTLINE section in Example on page 33). Figure 1-14 illustrates how an inappropriate accuracy can cause false areas. Although the IDF translator in Allegro PCB Editor verifies that the first and last coordinate of an area match, the mechanical engineer should be aware of this minor issue. If IDF detects such violations, the translator logs an error containing the line number in the IDF file that marks the beginning of the area definition, and continues with the next item in the IDF file. Figure 1-14 Accuracy in Pro/ENGINEER As indicated in Table 1-4, most of the ECAD areas related to the IDF flow are not allowed to contain voids. This relates to the Allegro PCB Editor implementation of the respective shapes.
