Something needs to be improved with the current UI as it pertains to failed sweep features. The vagueness of the information that appears when a swept feature fails is astonishing. What is needed is view-window highlighting of the specific problematic geometry/sketch element(s) causing the problem, along with nicely descriptive wording in the pop-up window that appears on the feature failing. As it currently operates, the user is given a vague "Try with different inputs" message, and nothing else to go on (see attached image file). This needs improved with the next release of Inventor.
