Necessity truly is the mother of invention. Here's an example. Someone (who will go unamed...OK, me) that does not scan every day, ran into a little problem. I'm working on a project for another article that involves scanning a disassembled mouse. I scanned one side, flipped it, and scanned the other without thinking too much about the model formation in Studio....and this is what I saw when I looked at the screen...
Both orientations of the scanned mouse are superimposed. At first I thought I would just selected the first ten models and be done with it...but where's the fun in that? So I decided to write a script that would (with all the models selected) allow me to select the points (on all the models) in an area of the scan data that I knew were part of the same orientation, and then merge them automatically.
Here's the hot scripting action...
The Support KB Nugget can be found here...and the python file and test data are available for download here.
Enjoy!
'''
SelectModels_by_ActiveSelections.py - Geomagic Helper Script
This script will walk the list of models and build a list of of their names
if they have data selected (i.e., active selections or"red" points, polys, or ordered grids/scans)
It will then construct a geo.select_objects macro and execute it.
Then, for this example, it will merge the scans associated with those selected models
Assumptions for this script and test data:
All model names must be unique.
The models cannot be Grouped.
The model data type is Ordered Points (Scans).
