Point Group to Nominal Group Relationship

This best fit alignment option best fits two groups of points together and creates a relationship in the tree. The alignment prompt will ask for the “nominal” or “reference point” group. This group is the destination of the transformation. After selecting the nominal group, a relationship will appear in the tree as well as an empty point group called GR-“picked group name”.

At this point you need to either measure points into the added point group or associate a previously measured group to the relationship. To associate a group to the relationship right click on the relationship in the tree and select “associate data > 2nd group” (1st group are the nominals).

After data is either associated or measured, right click the relationship, and choose “execute alignment”.
