The following tasks are frequently used when working with point cloud data.
Set up a data set and define settings
Each client computer on which Smart Isometrics is installed, must be set up to access point cloud data on the local computer or on a remote server. Also, to make a point cloud database available for use in Smart Isometrics, you must add it to the list of databases on the computer where it is stored. For more information, see Set up access to a point cloud data set in the Smart Isometrics Installation Guide. You can access this document using the Help > Printable Guides command in the software. After the local computer is set up, you can define settings that control how the point cloud is loaded and displayed in the software. Adjusting the settings can also help improve performance.
Connect to a data set and locate the required objects
Select which of the available point clouds you want to use. Then, use the commands on the View and 3D View toolbars, along with the Seek and Define Working Region commands on the Point Cloud toolbar, to navigate the point cloud and isolate the part of the data set that contains the section of pipeline that you want to model. This involves cropping the point cloud to reduce the volume of data so that you can focus on a specific part of the point cloud.
Compute the pipe centerline
The first step in building an as-built isometric for the selected pipeline is to fit cylinders to the selected piping in the point cloud. This is done by placing a single point on the surface of each pipe in the configuration. With each user-specified point, the software searches for associated points in the same region and uses this data to calculate measurements.
Create a referenced pipe sketch
Use the standard routing and component placement commands and tools in Smart Isometrics to create the basic pipe sketch and flesh out any fittings that exist in the point cloud data set.
Define the pipeline
Use drag and drop or copy and paste to transfer coordinate data and dimensions from the point cloud to the Smart Isometrics model to completely define the pipeline.
After all of the pipeline and component dimensions are fully defined, use the Generate Drawings command to run the referenced piping sketch through Isogen and create a high-quality, standard drawing deliverable.
