I have the same issue as Adam. The boundary blend tool ever seems to highlight no matter how many curves I have. Mark, maybe a step-by-step tutorial would be the best way to go. Thank you for your time. Rico
Are you using the Schools Edition? Mark does the Schools Edition have the boundary blend option? The only thing I've seen that disables the boundary blend icon or menu selection is an empty part or one of the three primary datum planes are missing. I think PRO\Surface is required so try checking for the option under Help>System Information (may vary depending on version) and look under the Configured Option Modules.
