Drawing Revisions

The Revision (REVI) element enables you to store drawing revision data. A REVI may be a member of a Drawing element or of a Sheet element, see Figure 9:3 below.

Figure 9:3. Revision Element

A REVI has the attributes:

• Approver (APPR)

• Date of Approval (APDT)

• Revision (RVSN)

• Revision text (STEXT)

• Date of Revision (RVDT)

• Revision Author (RVAU)

• Circulation List Reference (CLRF)

RVSN, RVDT and RVAU are all automatically set on REVI creation, but they can then be edited. The format of the date assigned to RVDT is controlled by the value of the DATEFOrmat attribute of the relevant DEPT.

Pseudo reference array attributes SREVAY and DREVAY are available to return a list of the reference of all the REVI elements owned by a Sheet or Drawing. The maximum array size is 50. The attributes are valid at any element of or below a Sheet or Drawing respectively. They have been created primarily for use with hash codewords to generate revision data on drawings, see Accessing Data from the Draft Database, Part 2, Drawing Annotation.
