If PC-DMIS still cannot find an appropriate point on all the CAD surfaces, it asks if it can create the Auto Vector Point and you can choose a nominal point later. If you accept, then PC-DMIS creates an Auto Vector Point in the Edit window and you can select from these options:
Option 1 - You can take a new hit and PC-DMIS will try to find a new nominal point. Essentially you're starting over if you do this.
Option 2 - You can choose a different nominal point from the dialog box and click the Override button. PC-DMIS will then override its earlier chosen nominal point with the new selected point for the recently created Auto Vector Point.
You will usually want to do this if you don't like the nominal point that PC-DMIS attempted to find in the procedures discussed in these topics:
Options 3 - You can select a CAD surface on the screen. PC-DMIS would then attempt to find nominal points on the selected surface and display those points in the FindNoms Override dialog box.
You can then override the previous found nominal, by selecting a point from this new surface and clicking Override.
PC-DMIS ignores the FindNoms tolerance with this option. So, even if the selected CAD surface is out of FindNoms tolerance, the dialog box still displays the points.
Option 4 - You can increase the FindNoms tolerance by changing the value in the Tolerance box and clicking the Apply button. PC-DMIS will then apply these procedures again, using the higher tolerance value and display any appropriate points:
You can then choose a valid point and click Override to accept a nominal point for the recently created Auto Vector Point.
Increasing the FindNoms tolerance in the Tolerance box has the same effect as changing the FindNoms tolerance from the General tab of the Setup Options dialog box.
