Clear Edge3d – lead of Automated Feature Extraction, laser scanning and 3D modeling space in USA with their fellows have present “33 Expert Tips, Tactics & Best Practices for As-Built BIM Project Success”. These are 33 valuable tips. Very thanks Clear Edge3d, we also see some tips that we want to share in a long time experience when providing scan to BIM service for USA clients.
#18: Filter & Cleanup Scan Data
Inevitably, the laser scanner will record a small amount of
unintended noise or artifacts in the form of stray points within the point
cloud. One example of an artifact may be a factory employee who walked through
a scene during the scan. Once the files are registered, clean up the data by
selecting and deleting those stray points. The resultant file will be more
useful downstream, especially if you’re using feature extraction software like
EdgeWise to speed the transition into an intelligent model
#19: Remove Unnecessary Scan Data for CAD
Reference but Maintain Full Scans for Client Visualization
Numerous circumstances might require a modeler to link scan data into modeling
software like Autodesk AutoCAD or Autodesk Revit. Design tools like the
aforementioned aren’t purpose-built for point cloud files and may produce
results that are visually confusing to extended team members or clients. Remove
or unlink the point cloud data in the modeling software once you’re done
referencing it or before you deliver the DWG, RVT, etc., to the client
#20: Coordinate CAD File Origins and Orientation
Before Finalizing Registration and File Translation
Importing scan data into CAD/BIM software is a common downstream use.
Synchronize CAD coordinate systems before finalizing registration. Doing so
will ensure quick and easy placement of scan files within CAD and makes
coordination with the team more fluid.
#21: Files Can Be Repositioned Within Revit…But Be Careful!
Proceed with caution: manually repositioning linked files in
Revit should only be used as a last resort! However, unique circumstances may
necessitate such a decision. One such scenario may be where you’ve been
contracted to verify as-built conditions against a design model. In this
circumstance, the design model may not be referenced to a geo-referenced
coordinate system. In this scenario, manually positioning the as-built model
can be managed locally within Revit. Additional scans can be inserted using the
“Auto-Origin to Last Placed” position. Be aware that if you attempt to merge
any data from other scanning applications, such as Edgewise, the resulting
insertion point will not be correct. Import all data before repositioning. -
#22: Start with a Good Revit Template and Sometimes the
One way to make a good impression with a client is to
deliver the as-built model within the guidelines of their unique CAD/BIM
standards and guidelines. It’s a simple request and will be much appreciated.
Just ask that they provide you with their Revit template at the onset of the
project. Then say “hello” to repeat business! - Greg Hale
Our take: With an outsourcing like us, this is very
important. Because of the difference between standards in 2 country, sometime
related with the thirt party (for the international client), to ensure
communication effectively, we need learn on the guidelines of their unique
CAD/BIM standards and guidelines. It make us more easily win in business.
#23: In Revit…Manage Links is Best to Load and Unload Point
Clouds as Needed. If you are working with very large point cloud files use the
“manage links” utility to load and unload the point cloud when needed. If you don’t,
the size of the scan files make bog down the performance of your computer as your
processors manage all that scan data
#24: Once Scans are Imported and Positioned Correctly in
Revit–Pin Them! Never, ever move your scans to fit your model…I’m serious…never!
Doing so can lead to so many downstream problems and has the potential to blow
your project. Don’t do it!
#26: Place RECAP Files on Their Own Worksets to the Client
Managing visibility settings in Revit is part art and part science. Place RECAP
files into their own workset allowing you to standardize which views show the
point cloud by default. Due to the size of point cloud files, your computers
RAM and processor will thank you. - Greg Hale
#27: Create and Utilize View Templates for Plans, Elevations,
Sections, and 3D Views Use View Templates to optimize view settings for
displaying scan data in Revit. It will save time when creating new views and
also ensure view consistency across your drawings, etc. - Greg Hale
#29: Check Work by Doing a Walkthrough for Your Client with
Using Color Overrides Autodesk Navisworks is a great tool
for aggregating and overlaying data. Once imported into Navisworks, walk
through the model to find errors and omissions within the model. Incorporate
this step into your delivery process to ensure a high quality product.
#31: Customer Service & Communication
Set yourself apart from your competition by treating your
customers the way that you’d like to be treated. Never forget that people want
to work with people. Be responsive and on-time. Think about each customer with
a long-term perspective: build relationships and trust.
Our take: From the other side of earth, we have 2 loyal
customers in USA. What make our successful? We are prior to communication and
consult to customers consecutively to increase quality service and satisfy
customer. We ensure that we will quickly clarify specific work requires,
be able to consult or feedback which valued to define tasks of work completely,
clear, help to decrease customer’s risk and maximize value for end users.
# 33: The Biggest & Baddest isn’t Necessarily the Best
in Computer Hardware
Many don’t realize this but Revit only uses one processing
core, so if you are doing a lot of Revit work, the benefits of a high-end eight
core or sixteen core workstation are lost. Where a multi-core machine comes in
handy is processing large data sets in applications. Four gigs of Video RAM is
plenty and will deliver the best speed of zoom / pan and changing views at a
