All members are inserted based on the positions specified by axis intersections. If, for any reason, you have to modify the position of the axes, the members that are inserted based on these axes must also be updated.
You can use the "Move Members to Axes" option in the "Review" tab or in the toolbar to automatically re-position the members based on modified axis intersections.
"Move Members to Axes" modifies all columns, walls, supports, beams, slabs and ribbed slabs based on the modified axis positions.
"Move Members to Axes" is a powerful feature that able to identify or eliminate corrupted members. Users are strongly advised to run "Move Members to Axes" from time to time to ensure the model is free from modelling errors or corrupted members.
Slab strips will not be updated based on the modified axes. Therefore, any reinforcement attached to the strips may be incompatible with the new geometry. You have to delete all affected steel bars and update them for the new plan geometry.
