Point toward Designation, Section Profile and Conn_Location Here, section details like designation and the profile are shown.
Point toward Mechanical Properties Below section details, we see Mechanical Properties.
Point to the properties. These properties get populated based on inputs in the Input Dock and the codal provisions
Point toward Dimensions Dimensions of the selected section are listed under the Dimensions section.
Point to the dimensions. These dimensions are fetched from the Indian Standard, IS 808 database of Osdag.
Point toward the section image A detailed and representative cross-section drawing of the selected section is shown.
point to the 2D drawing. This 2D drawing is typical and has standard notations marked over it for better visualisation.
Point toward Section Properties The sectional properties corresponding to the selected section are listed under Section Properties.
Point toward Section Properties fields These properties are also fetched from the Osdag database at run-time.
Only narration For a user-defined section not present in the database, properties are calculated by Osdag internally.
Only narration The properties of this user-defined section are inserted into the database for reuse.
Only narration Users can add single or multiple custom sections to the Osdag database and use it in design.
Point toward Add button The Add button at the bottom allows to Add a single custom section to the database.
Point toward the Download xlsx file, and Import xlsx file buttons For adding multiple sections at once using an excel sheet, use the Download and Import xlsx buttons.
Point toward the Download xlsx file, and Import xlsx file buttons We will explore this feature in another tutorial.
Point toward the Clear button The Clear button will clear the user-defined inputs in the Design Preference window.
Click on the Connector tab Let us move to the Connector tab.
Point toward the Inputs fields Here, we see the Material properties of the connector material.
Point toward the Material drop-down menu E 250 (Fe 410 W)A is selected by default.
