The building has a one or more floors input in the tree with a floor assembly that includes a Crawlspace. The input for the exterior perimeter of the Crawlspace (length facing to the outside) is too small for a crawlspace of this size.
If you did not mean to enter a floor with a crawlspace, find the raised floor selections in the building tree and select a different floor assembly that does not have a crawlspace.
To change the Crawlspace Perimeter, go to the top level of the building tree, select the Residential tab and enter the correct value.
