Hi, I’m trying to rescale a model to specific ratios (similar to photoshop’s image size function) and was wondering if there is a way to do this? I have been using the scale feature in slicerFab before I generate bitmaps, however this doesn’t give me the new measurements which is important to know. Is there a way to scale a model which updates the ROI measurements?

You can apply and harden a transform (set scale factors in the diagonals); or use the Surface Toolbox module.
