DIMENSION-HOW TO RECTIFY MOVING DIMENSIONS AFTER UPDATE
Try using Insert Point or Delete Point to modify existing automatic dimension chains as much as possible instead of creating new chains.
Deleted automatic dimensions should not come back on update unless there is somethign new to dimension (e.g. new holes rather than moved holes).
When moving existing labels and dims use the grips. Normally AS will remember the new positions.
When adding dimensions, or inserting points on existing dimensions, only use the osnap "Preferred for Manual Dimensions" and no other snap.
Any dimesnion point to any other snap point WILL disappear on update.
You will get a warning on the command line when you use any other snap and a red circle around the suspect point.

Open the ASMT Advance Steel Management Tools
Go to Settings>Defaults
Select Use filter and type Update in the filter field

Open the Objects snaps and disable all your object snaps, keeping only, Endpoint midpoint and node.
Clear all the object snaps on the 3D object snap panel.
Select "Preffered for Manual Dimensions" on the Steel Osnap tab.
You can insert or remove dimension points to or from a chain of dimensions using the Insert point tool on the Labels & Dimensions tab on the Parametric Dimensions panel.
Save and close the drawing then repeat Updates and the dimensions should stick.
I hope this helps.
