Thanks for yours replies I have tried in the past a trial version of Creator but i think my Vue Infinite 2016 is better The Pro version at the Black Friday price subscription seems ok I ask Bentley for a trial version . I download it from the link they give me but,after installation it display a message saying i have 0 days lefts for the trial...so no trial ..so i hesitate I reply to Bentley about it and wait .If i see enough gain for new version i will buy it....
