Digital Restoration: The Druid Hill Park Arch

 
The Story:
Druid Hill Park was part of the United States landscape design movement that also produced Central Park, and is one of the three oldest landscaped urban parks in the country along with Central Park in New York City and Fairmount Park in Philadelphia.  The 746 acre park, which resides in West Baltimore and is listed on the National Register of Historic Places, was purchased in 1860 by the Baltimore Park Commission from its owner Colonel Nicholas Rogers. Many buildings from the original estate remain a part of the park today.
The monumental and impressive entrance arch at Madison Avenue was designed and constructed from sandstone by George A Frederick architect for the Baltimore Park Commission and was completed in 1868, serving as the main entrance to the park until it was separated from the park proper by the completion of Druid Park Lake Drive. In 1961 the arch, declared to be a traffic hazard, was almost torn down but locals were able to raise $14,000 for the preservation of the arch and demolition was avoided.                                                                                                                                                                             return to full slide show
The Challenge:
John Milner & Associates appointed Direct Dimensions to capture the Druid Hill Arch in 3-dimensions to reverse engineer a 3D CAD model and 2D CAD elevation drawings that will aid in the restoration and conservation of the Arch.

The Solution:
  • 3D scan the arch on-site using a medium-range, spherical scanner
  • Compile data to create a both a digital 3D model and a point cloud
  • Create a perfected 3D model and 2D elevation drawings using CAD software
