When creating a drawing file from an assembly that has an exploded view there are times where the annotation balloon may not attach as intended while in the exploded state.
A common cause of this problem is creating the exploded view while in a perspective view mode in the assembly file. This view mode distorts the display of SOLIDWORKS and subsequent views created while enabled. If an exploded view is created while perspective view is enabled the SOLIDWORKS drawing view will have difficulties attaching annotations to parts because of this distortion (even if the model appears correct in the view).
Unfortunately simply disabling perspective mode will not correct the problem since the exploded view was already created with perspective mode enabled. The first step is to disable the Perspective view mode found in Views -> Display.
Once disabled, delete the exploded view from the configuration tab. This is to make sure the old view isn't accidentally used within the drawing file and the problem returns.
After creating a new exploded view, go back into your drawing and refresh the view pallet so it is updated with the assembly. Click on the drawing view you wanted to be in the exploded state and reference the newly created view.
Balloons should now attach as intended to the model in spots that previously failed to attach.
If balloons still fail to attach as intended, or no numbers appear and a ? or * show inside the circle, please contact Hawk Ridge Systems at 877.266.4469 for the U.S or 866.587.6803 for Canada for further troubleshooting and help.
