BNL NSLS II Presentation on Survey and Alignment using Point Cloud
1.
2. •Understand
how to use the Kubit programs
•Learn how to import data into Autodesk
products
•Work with the Survey and Alignment Group
and learn the scanning process
•Assist the Sr. Designer on the CHX beam line
with analyzing the scans created for her beam
line
•Create documentation to assist other
designers with using the Kubit software
4.
Architects/Engineers create 3D models and 2D
drawings using Autodesk products(AutoCAD and
Navisworks)
Carpenters use models and drawings to build the
structure
When complete, Survey and Alignment measures asbuilt conditions and shows deviations (VirtuSurv and
PointCloud)
Traditional measuring tools have limitations:
Laser track measuring can be slow and tedious
If a measurement is needed that was not taken, the
engineer must return to the site
Work flow may be halted
5. Scans are easy to set up and take only
minutes to run
Once scans are taken they can be
stored as PointCloud files
Scans maintain a millimeter of accuracy
within 30 meters and can be overlapped
to compete a large area
Scans can be directly imported into
AutoCAD and used to make an
accurate as-built model

7. Kubit Programs VirtuSurv and PointSense Plant are linked. Working in
VirtuSurv’s picture view sends points to AutoCAD. Making it simple and
seamless to model floors, walls, doors, piping and steel.
8. •PointCloud files are large and can cause
computers to run slowly
•Using varies modeling features from
PointSense and VirtuSurv, you can convert
a PointCloud file into a solid part for
practical use
•The PointCloud solid parts can be
exported as drawing files or even step files
and be used in other modeling and
viewing programs
•These files are much smaller and easier to
work with
13.
Modeling with a full PointCloud can be difficult because it contains so many
points. The sections manager can isolate points and get a better view on
areas of interest
Using section manager the floor can be isolated and changed into a
elevations map to understand floor discrepancies
This can be helpful in assuring a level experimental floor or to see where
building low points are for effective draining systems
19. •Allows users to create pipe runs by clicking points along the existing pipe
image in VirtuSurv
•Identifies pipe diameter, changes in pipe direction, and features in pipes
such as valves and flanges
•Kubit provides pipe catalogs with a wide variety of pipes but other catalogs
can be added
20. •If there is a particularly complicated pipe run or not enough data, users can
manually insert piping with the aid of VirtuSurv
•Above shows a manual insertion of a 90 degree elbow. Clicking along the
seam of the connecting pipe orients the pipe correctly
•Walk The Run is a quick way to lay piping but the run may look unaligned
when finished
21. •In complicated sections piping may be
off. This can be fixed with the “Constrain
Piping” feature which uses the PointCloud
to fix runs
22. •This Feature also creates a centerline for the
piping for which a tie in point can be
displayed
23. •Tie in points can assure correct installation of pipes into equipment, supply
and return lines, as well as other piping runs
25. •PointSense Plant comes with a large steel catalog and other catalogs
and profiles can be added
•Even if the exact size of the steel is unknown, as long as the size is
relatively close, any size steel can be fit and swapped until a desired fit
is obtained
•Steel is more involved than piping but if enough data is present and
steel sizes are known it can be very simple
26. •Clicking along the steel run in VirtuSurv fits it into the AutoCAD
pointcloud
•After a beam is fit it can be edited by rotating, re-fitting, or changing
the steel profile
•Steel can also be extended to other steel or to a defined point
27. •Steel can also be
automatically
constrained; but
manually extending
steel to points
usually works best
31.
Three dimensional scanning is a powerful tool
that can be used to create models that
accurately depict the as-built world
Measurements can be taken off of the models
and as-built features can be used to complete
the final design stages of a project
PointCloud files can be converted to solid
objects using Kubit’s PointSense software in the
AutoCAD environment
Kubit PointSense modeling features allow for
accurate solid representation of as-built
conditions; allowing designers to create an
accurate model
