Works fine in DxDesigner, no problem with that. It is how to control the eDXD view when running Expedition - this still defaults to resizing around selected component
At the moment there is no control for this from within the tools.
One more reason to finally introduce a xDXD read only option, that would solve this. No need to use this awkward eDxD Viewer ;-)
I am not sure if you are aware of the movement to inspire Mentor to ditch eDxD Viewer.
The alternative would be to have xDxD Designer function as read-only, no-license, as a viewer.
If you use the license, then you add the full functionality of the xDxD tool.
Your suggestion is well know, but if you try to read a design on a read only medium. e.g. a CD (remember them?) then you will not be able to do this, because the xDxD will still try to read/write to the dir where the design is located.
So even if the option exists to start xDxD with the -readonly switch, it is not a real read only modus.
Plus, there is a case, i don't remember the details, where you can override the read only flag and happily modify the design.
Having said that the read only option that you are mentioning is a pseudo-read only imitation, not a real read only function.
So please join us in the idea web site and support the read only xDxD tool idea.
