Results table time display update 

Addressed a rare display issue in the Time column of result tables where seconds occasionally appeared as decimal values instead of the standard H:M:S format. 

Default values not updating for Weirs2D and Orifices2D 

Resolved an occasional problem where default values for Weirs2D and Orifices2D did not refresh automatically after establishing a successful 1D–2D connection during model setup. 

False error message while importing .inp files 

Corrected an issue that generated false error messages during .inp file import, even though the file was successfully processed and the GeoSWMM project created properly. 

Error when setting custom coordinate system 

Improved stability when assigning a user-defined projection or coordinate system that differs from the ArcGIS Pro map coordinate system. 

Error during importing boundary layer for 2D model 

Resolved an issue where attribute fields were not displayed correctly when importing a boundary polygon layer for a 2D model. The attribute table display has been fully corrected in this version. 

Default 1D feature settings after enabling 2D model 

Updated the workflow to ensure that default configurations for 1D features are correctly applied when converting a 1D model to a 2D model. 

Missing Unique IDs for Weirs2D and Orifices2D 

Ensured that unique IDs are consistently assigned to Weirs2D and Orifices2D after establishing 1D–2D connections. 

Improved workflow for generating SFP 

Enhanced the Surface Flow Path (SFP) workflow to prevent errors that could occur in certain cases during generation, ensuring accurate and reliable path creation. 

Improved workflow for delineating headwatershed 

Refined the delineation process to automatically correct cases where some headwater areas were previously generated too small and required multiple iterations with snap distance adjustments. 

Improved workflow during watershed delineation 

Enhanced the watershed delineation process to maintain functionality after GIS edits—such as deleting or splitting delineated streams—ensuring smooth operation during subsequent delineations. 

Enhanced system performance and stability 

Optimized overall performance when input data extends beyond the study watershed boundary (for example, when using large DEMs for slope calculations). This enhancement improves efficiency, reduces processing time, and increases stability during intensive computational tasks. 

Resolved user interface issues 

Improved several user interface elements, including clearer tool header titles and enhanced information display within object properties windows.
