► McCoy House

(http://www.owensmccoyhouse.com/)

• Historical house built in 1840

• Known structural issues addition

• Scanned exterior with a Faro Focus

• Used Microstation to show elevation bases on ACS to

show deviation in walls

► Visual Explorer

• Flashlight Mode – Provides a perception of depth

► Highlighted area is larger the further away the cursor

is

• Cross Section Mode – Uses a 3D cylinder to highlight

points

► 3D Line Following

• Used to trace things such as striping

• Designed to be used with Intensity Presentation Style

9

► Snap Element

• Used to snap an existing element to a point cloud

• Works similar to Drape tool but does not add vertices

based on points

► Fit Cylinder

• Used to fit a cylinder to a point cloud

• Typically used for extracting pipes

► Model by Section

• Create section

• Create template

• Place template at each section interval
