Review & Build

This is the final step where you can review your design before creating the simulation model.

• Color Bar: A scaled diagram of your catheter design, with the proximal end on the left and the distal tip on the right. A black line indicates the pullwire termination point.
• Configuration Summary: Review all entered parameters before building the model, laid out as cards across the width of the window. Click the "Edit" link next to any item to return to that step and make changes; the per-section laminate cards take you to that section's Construction page.
• Peel-away Illustrations: The illustrations are created parametrically for each section and accurately reflect the scale and composition. Pullwire lumens are cut through the stack at their per-section dimensions, lumen liners appear as white sleeves, and, when the wire cross-section is specified, each pull wire renders in dark gray metal, emerging from its lumen at the distal end. To copy the illustration for sharing, right-click and select Copy.
• Save Config to File: Saves the current catheter design to a file. This allows you to reload the design later or share it with colleagues. This function is also available from the main menu via File > Save Config.
• Build Model: Click this button to generate the simulation. VirtuCath builds the physics model from your inputs and lands on Catheter Analysis, where the design's computed properties are. Building also unlocks the deeper-analysis and fabrication tabs.

JSON schema reference: The catheter .json file follows a versioned schema you can introspect at runtime via the CLI API's export_schema command. This is the canonical reference for the file format and is the best entry point for scripting or AI-agent workflows.
