Hello, here we are working in collaborative work (about ten people). I wish I could make an assembly plan for our workshop and that if someone "has fun" modifying the 3d assembly for me there is an alert when I open the plan and that it does not automatically modify it. That I can keep the possibility of refusing the modification.
The 3D plane is associated with the plane but not the other way around. As a result, each user must check where a 3D is used (for example by right-clicking on the --> move) file before launching his modifications.
Look with a detached drawing, it does not update the plans automatically it is up to you using the red light green light to update or not your plan. For alerts in option => color, check the box "use the specified color for modified drawing dimensions when opened" this way if you update the detached drawing, the dimensions that change change color so easy to spot.
Review your distribution process with separation of access according to needs: the design office makes changes, the workshop can consult (via PDF, eDrawing).
