I am a new user of Tank 2019.

In trying to define the roof data in the "General Roof Specs" Tab the Net Area Scratchpad does not seem to accept any values for conditions except those with angles. I am trying to define a roof-shell connection of type "e".

The 3D model also does not appear to be able to display anything but an angle connection at the roof to shell connection either.

Is this a user error, version limitation, or something else?

Thank you,
