The document is a presentation by Naksha Tech Pvt. Ltd. on 3D modeling. It discusses laser scanning as a process to capture 3D surface data of objects using a laser and camera. It then outlines Naksha Tech's 3D modeling workflow including pre-processing captured point cloud data, producing 3D models, quality control checks, and output delivery in formats like AutoCAD, Revit, and Cyclone. Examples of 3D modeling projects are also shown for buildings, industrial facilities, oil and gas plants, and more.

2. Laser Scanning
2
• Laser Scanning is the process of shining a structured laser line over the surface of an
object in order to collect 3-dimensional data. The surface data is captured by a camera
sensor mounted in the laser scanner which records accurate dense 3D points in space.
• We uses 3D laser scan surveys to reverse engineering intelligent or non intelligent, accurate as-
built 3D models, rapidly and low cost we gives the prospect of affordable 3D models for all
clients.
We model:
 BIM (Building Information Modeling)
 Industrial Facility
 Oil and gas Plant
 Floor Plans, elevation and cross section
 Bridges, roads, tunnel and railways
 Heritage buildings
• Data captured by a 3D scanner is called point cloud. Each point represents one measurement in
space.

4. Input Received:
We receive the data in different format like ( imp, pts, faro, pcg, text, xyz) then we
will convert this to required format.
Processing data:
We check the data for point cloud density, registration and any defect or error in the
point cloud. Then we will process it to the working environment.
Production:
We are having individual experts for modeling in specialized categories. We divide
the work in individual category and later we will merge into single file. Then it will go to QC
process

5. Quality Control:
Data will be checked for quality as per client specification, and will check for
clashing and missing objects. Later file will send back for correction.
Quality Assurance:
We will take a small part of completed data for quality check and we will check
whether it meets to client expectation, based on the acceptance ratio we will deliver the
project if not we will send it back to production for corrections.
Output Delivery:
We will deliver the data in required format.
