<p>We reviewed the Use Case Scenarios developed by David Odendahl of
Boeing (sent in a previous e-mail). We agreed the next step should
be gathering inputs for additional scenarios. <b><u>These are
requested by Friday</u></b>.</p>
<p>We reviewed the possible requirement for tools with multiple
models. We agreed that an application might need to make use of
multiple tool models to meet the requirements of difference
scenarios such a force computation, collision detection, etc.
However, we decided that a STEP-NC Project would not need to
indicate which model should be used for each workingstep, so the
requirement is already being met by the current ability of STEP to
include alternate models for a product.</p>
<p>We reviewed the proposal for a new version of Part 21 to support
digital twinning and the digital thread. This was a first
presentation so no firm decisions were made. It was suggested that
the new standard should be a part of ISO 23247 because its scope
will include QIF, MTConnect and other data formats. It was
recommended to use ZIP files to bundle the multiple formats. A
session on the topic will be included in the WG11 and WG15
schedules for Chicago (latest attached).</p>
