You can add Node to node dimensions in the Geometry view. From Ribbon Interface, Tools-> Dimension, select 'Add Dimension Lines'. You can add dimension lines between column nodes as well as meshed nodes for mat foundation.

• Support to support dimension — This new feature can be used to get the dimension between two supports.
• Meshed node dimension — For Mat Foundation, two new tools are available in the Dimension group of the Tools ribbon tab which can be used to calculate the dimension between the meshed nodes.
