I'm using ArcGIS Pro 3.0.1. I would like to export several ModelBuilder layouts for a publication. Models I built myself all look the same: same color for elements like input data/tools/output data, all without outline. Another model I downloaded and modified shows different colors and black outlines. I wanted to change that, but I don't know how. Couldn't find anything like "Display properties". Diagram properties also only let me format the font. I guess it must be possible, otherwise I wonder how the downloaded model was modified.
Does anyone know?
