How to control the object snap behavior associated with hatch patterns and extension lines in AutoCAD

Lynn Allen, presents this exclusive cad video that demonstrates how to control the object snap behavior when it connects to hatch patterns and extension lines in AutoCAD.

Have you ever tried to grab the endpoint of an extension line instead of the anticipated object, or grab the seperate objects in a crosshatch pattern, then this AutoCAD video tutorial is ideal for you.

To install custom hatch patterns into AutoCAD, follow the steps, given below.

Copy your hatch pattern PAT file(s) into the default Support folder that AutoCAD employs to locate hatch patterns. The default path is mentioned in the Support File Search Path list under the Files tab in Options. It is normally the first one displayed. It is the one that goes to your user folder.

Watch the following youtube video for getting more information.

Bentley System launched OpenRail – A robust BIM software for design & maintenance of rail and transit infrastructure

Bentley System launched OpenRail design and maintenance software to apply BIM for the broad planning, engineering, project delivery, and operations of rail and transit infrastructure.

It deals with vertical and horizontal track geometry as well as produce 3D models for analysis and visualization and reports for cost estimates and setting-out, and product construction deliverables. OpenRail will get together digital components and digital context, during digital workflows.

OpenRail applications will consist of OpenRail ConceptStation which can be used for conceptual railway planning and design. In future, OpenRail Designer will be accessible for detailed engineering and 3D design of track, overhead line, tunnels, bridges, and interrelated civil infrastructure and AECOsim Station Designer will be applicable for the comprehensive modeling of rail and transit stations.

OpenRail is developed on the basis of a connected data environment that includes the shared services of ProjectWise and AssetWise, as configured particularly for rail systems engineering workflows. Throughout project delivery, ProjectWise allows the collaboration between distributed engineering teams, coordination of structured workflows, and connected project visibility. For OpenRail, AssetWise delivers asset lifecycle information services for linear, network and geospatial referencing, corridor maintenance decision support, inspection workflows, and reliability and change management.

OpenRail CDE services contain Components Center for digital components, ContextShare for digital context, ComplyPro for progressive assurance, and ConstructSim Completions for accessing operational readiness.

Components Center is an Azure cloud service of libraries which arrange, across disciplines and applications, the semantic content of catalogued components, potentially including vendor data, fabrication details, component requirements (for example, electrical specifications and connections), reliability characteristics, and representational views necessary for documentation (as for instance, 3D, plan, schematic). A digital component is reprocessed across BIM workflows in design modeling, analytical modeling, construction modeling, and asset registries—from catalogued component, to engineered component, to installed component, to operated component.

BIM for Renovation of Historical Sites

BIM is shading off the conventional drawing rapidly. Building Information Modeling (BIM) introduces a new way for designing, constructing and operating buildings and infrastructure. The application stretches far beyond the known territory and it also touches the history with its best features and applications. For understanding the building designs and materials of historical sites, BIM brings out an unparalleled approach. Renovating buildings centuries old requires a comprehensive knowledge of structural designs.

The most known problem associated with renovating historical sites is identifying the structural design. BIM comes as a boon for the organizations that are conducting such works. They revealed that scanning the old construction is like lifting the pages of history and bring out the architectural theories decades ago. BIM has been used for surveying sites accurately that carve out the foundation step of planning the renovation work as per the structure needs.

Mapping historical sites let you understand how the materials have been used and transformed over times. BIM has been used in renovating the Attucks school in Kansas City. The red building was built in 1905 by Charles A. Smith. The building stands in the test of time as a historical site of the colonial revival influences and it has a great influence in the education history of the African-American community.

Nearly two decades after, Charles A. Smith was approached to extend the historical building with a two-story wing to eliminate the over-crowding issue. The task was challenging since Smith needed to match the aesthetic essence of the building while designing the extending part. He used original architectural detail to recreate the same value created decades back. Getting the complete details of the building was not easy and it needed a thorough survey.

Redeveloping Attucks in a new way was a complex task for the team and it required to unveil the existing structural design in the infrastructure. BHC RHODES, a civil engineering firm, shouldered the responsibility of offering 3D Revit Building Information Model. The company used the lider 3D mobile mapping of GeoSLAM conduct the survey work magnificently.

The survey brought out some necessary factors that were essential for carrying out the renovation work safely. The team revealed information about the deteriorating conditions of the wooden flooring, a possibility of ceiling collapses and poor air quality.

The revealed information helped the workers on site plan their job in a secure way. The firm took help from GeoSLAM ZEB-REVO for mapping the inside of the building. The lightweight, a mobile device used the 3D Simultaneous Localization and Mapping (SLAM) technology to perform the required job efficiently. The process is considered to be comparatively cost effective one to terrestrial, static or trolley based systems.

ZEB-REVO is incredibly designed for mobile mapping and surveying for multi-storied buildings. The device allows you to scan the inside of a construction just while walking around. For the Attucks School, the data received by this device generated 200BIM models.

The application of BIM in layering the historical sites proves to be a new approach. It opens up an array of benefits that lead to a flawless working ability. Sometimes the owner of building needs details about how the renovation work will be done and which material will be the best for work. BIM presents a design that contains every detail required for getting a quick approval on the proposed plan.
