Importing Third-Party Calculations (Beta)

File → Import Calc reads an existing hydraulic calculation out of another program's report and turns it into an editable CaidentCalc project.

Supported inputs: HASS .sdf data files, HASS report PDFs, AutoSPRINK report PDFs, and Hydratec (HydraCAD) report PDFs. Only Hazen-Williams calculations are supported at this time.

The flow: the beta notice → the usual unsaved-changes guard (importing replaces the open project) → a file dialog (*.pdf, *.sdf) → a short "Importing calculation PDF…" pass while the report is read.

The mapping wizard

Every pipe type found in the report gets a card: the imported spec on the left, and what it will become in CaidentCalc on the right.

• The header shows the project, source program, and pipe-type count; a Target pipe table selector picks where matches are looked up; multi-system reports add an Imported area selector — map each area separately.
• The tally chips summarize the state at a glance: exact · near · data loss · custom.
• Per card, two choices:
  • Match to Caident Pipe — bind the imported pipe to an entry in your table. The wizard pre-suggests the closest match and highlights every difference (ID, C value, fitting lengths); statuses grade the match (Exact / Near / Data loss). Binding to a pipe that lacks some imported fittings warns you exactly what would be dropped — with a one-click escape to custom.
  • Import as Custom Pipe — keep the imported spec exactly as-is, project-local (optionally also saved into one of your pipe tables). This is the no-data-loss default whenever a clean match doesn't exist.
• ⚠ Import notes above the cards list everything the importer wants you to verify — including a prominent caveat when the source used Darcy-Weisbach friction (CaidentCalc solves Hazen-Williams, so losses won't reproduce exactly; assign appropriate C values and re-solve).
• Reset suggestions returns every card to the wizard's original proposal.

Apply import → loads the project into the calc editor, unsaved, with the window titled "Imported 3rd Party Calculation: <name>" until you save it as a .ccalc.
