Checks ETABS building models for plan and vertical irregularities as defined by seismic design codes. Generates a summary report with pass/fail status for each irregularity type.

Generates complete sets of load combinations directly inside ETABS or SAP2000. Select your design code and load types — the extension creates and assigns all required combinations.

Calculates wind loads on buildings and structures per design code and applies them as lateral loads in the open ETABS or SAP2000 model. Handles basic and exposure-adjusted wind pressures.

Calculates equivalent static seismic base shear and applies it as a lateral load pattern in ETABS or SAP2000. Supports the static force procedure from multiple codes.

Calculates geometric section properties — area, moment of inertia, section modulus, radius of gyration — for standard and custom cross-sections. Displays results inside the CSI software panel.

Generates a concise summary of the open model — element counts, material and section assignments, load cases, and analysis settings — as a formatted PDF report.
