I can't get the singular base expansion

[dks35]

hello friends, I have a single storey steel project, I created a foundation system with a single foundation and tie beams. but I can't get the single basic expansions, if anyone has knowledge, I would be very grateful

First define the short reinforced concrete columns and then draw the steel columns on them. Define a single foundation under the reinforced concrete columns. Then you can get the individual base details.
