my aim is to modell a roving based on support points. I already found the object type "Curved Elliptical Fiber" in the "Create/Add GAD Object"-Dialog, where I can input the 3d-Coordinates of support points. As I have around 700 support points, it would be interesting to know if there is a way to input them with a macro or maybe by using an excel-sheet.

My support points are currently saved as triples (touple with 3 elements) within a python array. Is there an easy way to use these triples as an input for modelling?

Thanks for helping.

CT, ┬ÁCT and FIB-SEM / Coordinate Transformation after Cropping
« on: June 14, 2021, 11:30:12 AM »

I am currently analysing a micro-CT Scan of a woven fabric. Therefore I have to manually cut out single rovings using ProcessGeo -> Crop. Subsequently I want to determine the coordinates of the centroids for every single slice of the roving-cut.
When using ProcessGeo->Crop, a new coordinate-system is introduced ("local" concerning the roving-cut). The determined centroid coordinates refer to this local coordinate-system. However, I am interested in the "global" coordinates of the centroid. Global in this case means reffering to the coordinate-system of the whole micro-Ct Scan. I am searching for a possibility to transfer the "local" coordinates to the "global" coordinate-system.

My Idea was to save the Crop-Settings when cutting out the roving and later use the number of voxel I cutted to perform the coordinate-transformation. The Crop-Settings are saved as a .gps file. Is there a way to read the number of voxel I cutted from this .gps file? As my analysis regards many rovings, it would be helpful if a Macro could read the mentioned voxel-number so that I am able to perform the coordinate transformation using Python.

Thank you for your answer.

Kind regards
