Beral:

Here's a workaround.

Import this model and make sure its orientation is correct. Combine 4 to make a circle, and use Group , or Export as OBJ, or Export as furniture . You can than give it any height (close to zero) and diameter to indicate the space a round table with chairs occupies.

In the same way you could make an object from 4 thin boxes and export/import it to form a square.
