Modify and Re-solve Constraints
Used to graphically modify a dimension-driven profile. This tool is particularly helpful in visualizing the remaining degrees of freedom in a profile while applying constraints.
In some cases, you can manipulate the question marks interactively, or you can manipulate attachments that are flagged by question marks to investigate a profile's ambiguities with Constructions turned off.
To isolate the effects of interactive manipulations and make the tool more responsive, the Modify and Re-solve Constraints tool tries to freeze as many of the model's degrees of freedom as possible.
