I've had a user ask about changing the color of weak dimensions as displayed in sketcher. I have to agree with him when he says the gray can sometimes be easily overlooked. I've found it's controlled by the system color setting for "highlight - secondary", but that also controls the color of the "back"face of datum planes. He might be willing to live with the face of datum planes changing, but sometimes these settings have weird hooks into other functions or features that are not immediately evident. Does anyone know if it controls the color for anything else? Does anyone know of a different way to make weak dimensions stand out more?
Steve Smith had an excellent suggestion in the WF4 upgrade guide I bought from him, which we have used herewith great success and user approval. I have made weak dimensions/constraints purple, which follows a consistent meme with created dimensions in drawings that have lost their references. You see purple, you need to do something about it. Strong dimensions and constraints are green (green means go!) and locked dimensions are orange (no good meme here, I can't remember ifthis isthe default).
Not sure if this helps you with WF3, maybe something to look forward to?
