Hello,
I am using both Tekla structural designer and Robot, for most cases robot has more depth and functionality but on the other hand the ease of use is not that great.
I can easily show failed or passed members just couple of clicks with TSD but on the robot side, things got complicated I mean it is not a bad thing, but it will be nice to have a button on the main UI that shows the passed/failed results for each designed member. Robot has already those features within maps on members just implementing a shortcut is much appreciated.
