A video is nice, a .skp file is better! Pls upload the component, someone might have a look.
Though the Dynamic Components can act buggy, there are some of us whom has found way’s or ‘workarounds’ to cope with.
Bug 1,3:
Did you, in the process of drawing, scale at any time?
Bug 2: changing the options or ‘settings’ of a DC does not alter the options or settings of the other instances, that is the whole point of the DC, so please elaborate what you would like to see happening?
Bug 4: due to the deviated Trimble connect bug, I am not really sure if you purged before deleting the inserted component. Leftovers might be there. Did you know that the 3D text tools are inserted as components with the name of the text?
This can cause confusing as well.
Btw: if you update the Trimble Connect extension via the Extension Warehouse, you won’t be bogged again, numerous threads around here on the forum:
