I will focus on the Move command because it will likely generate the most interest from customers.<IMG __jive_id="22774" alt="a_tip_6.jpg" class="jive-image" src="https://community.ptc.com/legacyfs/online/22774_a_tip_6.jpg" />There are 3 types of move options: move with dragger; move by dimension; and move by assembly.  Move with dragger enables users to translate and rotate the geometry in the X, Y, and Z directions via a 3D handle.  The arrows enable 1D translation, the semi-circles enable 1D rotation, the fans between the arrows enable 2D translation in that plane, and the ball allows 3D translation.<IMG __jive_id="22775" alt="a_tip_7.jpg" class="jive-image" src="https://community.ptc.com/legacyfs/online/22775_a_tip_7.jpg" /><IMG __jive_id="22777" alt="a_tip_7a.jpg" class="jive-image" src="https://community.ptc.com/legacyfs/online/22777_a_tip_7a.jpg" /><IMG __jive_id="22776" alt="a_tip_7b.jpg" class="jive-image" src="https://community.ptc.com/legacyfs/online/22776_a_tip_7b.jpg" />After the move command is started and the geometry selected, a default handle is automatically activated providing intuitive visual feedback.  If there is a need to move the geometry other than the default placement of the 3D handle, users can select existing geometry or datums to control moves.  Also, there is an option to create datum features on the fly to create a movement reference.  An example move could be, tranlate 0.5in via the default X-arrow, select an edge from the geometry for a 10 degree Y-axis rotation, and create a datum plane on the fly for a plane move.  The steps of a move are under the Steps tab where the handle placements and moves can be reviewed and edited.  Mutliple steps are included in 1 move to reduce complexity of the number of move in the model tree.<IMG __jive_id="22778" alt="a_tip_8.jpg" class="jive-image" src="https://community.ptc.com/legacyfs/online/22778_a_tip_8.jpg" />Move by dimension enables the user to create a dimensioning scheme to move the geometry with an angular dimension or up to 3 linear dimensions.  The first movement reference must be a ground reference and the second reference must be part of the selected reference to move.  For example, the ground reference could be a mating surface and the second reference could be the central axis on a boss.  There is no 3D handle in this process, but there are drag handles similar to those when placing other features such as a hole.<IMG __jive_id="22779" alt="a_tip_9a.jpg" class="jive-image" src="https://community.ptc.com/legacyfs/online/22779_a_tip_9a.jpg" /><IMG __jive_id="22780" alt="a_tip_9b.jpg" class="jive-image" src="https://community.ptc.com/legacyfs/online/22780_a_tip_9b.jpg" /><IMG __jive_id="22781" alt="a_tip_9c.jpg" class="jive-image" src="https://community.ptc.com/legacyfs/online/22781_a_tip_9c.jpg" /><IMG __jive_id="22782" alt="a_tip_9d.jpg" class="jive-image" src="https://community.ptc.com/legacyfs/online/22782_a_tip_9d.jpg" />The last move option is move by assembly which follows the typical assembly process via assembly constraints.<IMG __jive_id="22783" alt="a_tip_10.jpg" class="jive-image" src="https://community.ptc.com/legacyfs/online/22783_a_tip_10.jpg" />In this example, the top of boss on the right side was lowered to be coincident with the boss on the left side.  Multiple constraints can be used on the move to achieve the desired effect.  Those familiar with assembly constraints should be able to learn this command very quickly.<IMG __jive_id="22784" alt="a_tip_11a.jpg" class="jive-image" src="https://community.ptc.com/legacyfs/online/22784_a_tip_11a.jpg" /><IMG __jive_id="22785" alt="a_tip_11b.jpg" class="jive-image" src="https://community.ptc.com/legacyfs/online/22785_a_tip_11b.jpg" /><H4 id="toc-hId--1271910055">Recognition</H4>One of the problems with non-native CAD data is the difficulty of making changes.  With flex modeling extension, non-native data with linear or radial patterns can be recognized and modified.  In this example, the cut selected in green is 1 of 12 members in a radial pattern on this part.<IMG __jive_id="22787" alt="a_tip_12a.jpg" class="jive-image" src="https://community.ptc.com/legacyfs/online/22787_a_tip_12a.jpg" /><IMG __jive_id="22786" alt="a_tip_12b.jpg" class="jive-image" src="https://community.ptc.com/legacyfs/online/22786_a_tip_12b.jpg" />Now these pattern members can be modified simultaneously with the flexible modeling tools.<IMG __jive_id="22788" alt="a_tip_13.jpg" class="jive-image" src="https://community.ptc.com/legacyfs/online/22788_a_tip_13.jpg" />The Flex Modeling Extension provides a small yet effective set of direct modeling capabilities within a parametric environment without losing the benefits of parametric design.
