The Chained Dimension Option is really missing in Layout.
The current dimensions are single ones.
I work with Vectorworks, and a chained dimension are for example 12 dimensions chained together.
So instead of placing or moving 1 dimension at a time a chained dimensions saves you lots of time.
I’m an architect and I use Sketchup and Layout for all my drawings.
This would be a huge timesaver.
If you like we can set up a Teamviewer meeting and I can show you how this works in Vectorworks.
