I have started to learn Tekla Structures v19. I want to make a basic steel project. But I cant do something. I add the U.S. Base Plate (1047) below to I profile and then There is a kind of mistake. How can I open bolt holes? Secondly, When I add the that base plate to another I profile, New base plates shown as a red cone. Is this a problem?
I hope You can understand my problem that images.
Base Plate Inquire You can see that, There are no bolt holes.
