Mark LaBell Jr – Technical Leader, SSOE Group DEMYSTIFYING LARGE POINT CLOUD DATA SETS FOR SIMPLE INTEGRATION ON COMPLEX PROJECTS Project Execution Where are we now? • Prior to May 2014 few projects were scanned • Past 10 months we have spent > $0.5MM USD on scanning facilities for our clients • Over 50 projects have been scanned since May 2014 • Construction value > $750MM USD What changed? Applications used NAVISWORKS REVIT RECAP/RECAP 360 MICROSTATION V8i PLANT 3D CIVIL 3D INVENTOR KUBIT POINTSENSE PLANT POINTOOLS So how do we get data to another office and most importantly fast? Storage Setup • Large projects > 50GB users have 2nd HDD (SSD) with a robocopy routine to mirror network – Robocopy routine is specific to each project • Small projects < 50GB users point directly to network drive • Both drives have the same map IE. P:\client1\project1 Storage Setup cont. • DFS is utilized to create a point cloud directory in each office – If local P:\ doesn’t exist then failover to closest office • Robocopy routine is run in server task manager to sync data between offices that need data • ReCap 360 utilized for non-modeling staff and project stakeholders Simple Network Diagram Large Projects > 50GB *Data is copied between offices via robocopy during off hours Simple Network Diagram Small Projects < 50GB *Data is copied between offices via robocopy during off hours How to make a large project small… • Always edit data on local hard drive, NEVER edit on a network • Make sure that you have a SSD – Single largest performance increase with minimal capital investment. • Make sure Ortho is set in ReCap • Always do editing in unified data set How to make a large project small… • Export data as is when you get spinning wheel of death • Have two computers to post process data • For tips to utilize ReCap on a remote desktop refer to handout Laser Scans Pre Edit Laser Scans Post Edit Demo Plans/2D References +/- of RCP files with Regions • + Saves time for exporting each region • - Navis and Revit do not support regions • + Regions can control visibility in AutoCAD and ReCap • - Regions are a confusing concept for the nonReCap user. • - Regions still process data while loading, therefore they don’t reduce model load times Tips for Referencing RCS data • Do breakdown scans based on sheet breakdown and S.O.W. – Minimize crop regions for point clouds, performance is drastically decreased in Revit model • Create a work set for PointCloud models • Create a master NWF for point clouds only RECAP DEMO Planning for Reality Capture Reality Capture Spec • Define processes of your firm – How you use the data including examples – Minimum requirements for good data acquisition • Define project S.O.W. • Send 2D docs and pictures from site visit to vendor – Narrative of each attachment is crucial for good scope definition. • Define scanning service requested – Pre Demo, Post demo, As-built, Slab Flatness, Site Survey, GPR Reality Capture Spec cont. • Define the scanning area – Interior, Exterior, Roof, Above ceiling • Declare safety requirements • Declare deliverables and tolerances of registration – File formats, file transfer method, be sure to request raw data SPEC DEMO Questions? • Contact Information Mark LaBell Jr Email: [email protected] Twitter: @mark_labell_jr LinkedIn: www.linkedin.com/marklabelljr Phone: 734.262.1523
