Export lift-engineering data

Send panel data to a lift-engineering firm for crane-lift and brace analysis.

Tilt-up panels are cast flat and tilted vertical by crane, so each panel’s lifting inserts (pick points) and temporary braces must be engineered for the lift. That analysis is normally delegated to a lift-engineering firm — the panel specialty engineer who sizes the inserts, lays out the rigging, and designs the bracing. ConstructiVision exports the panel data that engineer needs — geometry, openings, pick points, brace points, embeds — so nobody re-enters it by hand from the panel book.

What the export contains

Whatever the file format, the engineer receives the same substance:

Data

Why the engineer needs it

Panel geometry

Outline, thickness, and top shape drive the panel’s weight and center of gravity.

Openings and recesses

Every void shifts the center of gravity and weakens lifting sections.

Pick points

The proposed lifting-insert layout the firm confirms or adjusts.

Brace points

The proposed brace-insert layout for the temporary bracing design.

Ledgers, embeds, and thickened areas

Added weight and attachment hardware that affect the lift.

Export the panel data files

ConstructiVision keeps a structured, machine-readable copy of every panel current automatically:

  1. Make sure the panels carry their pick points and brace points (add them from Main Panel Details if they are not yet placed — see Add pick points and brace points).

  2. Confirm each panel with OK as you normally would. On every panel save, ConstructiVision writes that panel’s data file — mark.cvpanel — into the project folder, next to the drawings, and refreshes the project-wide bundle project.cvp that folds every panel in. No extra export step: an up-to-date panel drawing means an up-to-date data file.

  3. Collect the files from the project folder — the single project.cvp carries the whole project, or send the individual .cvpanel files for just the panels in question.

  4. Send them to the firm, together with your panel book (Print a panel book) so the engineer can verify the data against the issued drawings.

The .cvpanel / .cvp files are ConstructiVision’s native structured format — complete, current, and readable in Using cv-web, where panel sets can be reviewed and analyzed directly (Analyze panel sets).

Firm-specific formats

Dedicated firm formats are being reconnected

Earlier ConstructiVision versions wrote each firm’s own interchange file — Dayton/Richmond (.pdx), Meadow-Burke (.txt), and WSB / WorkShop Engineering (.pan) — as prefix_ENGINEERING files in the project folder, with a matching import that read the firm’s engineered layout back onto the panels. Those format writers exist in this build, but the Engineering Export dialog that selects the firm and runs them is not wired up yet — there is no menu command that produces a firm-format file in the current build. Until that lands, the .cvpanel / .cvp route above is the way to hand off panel data.

Notes

  • Keep panel edits inside ConstructiVision. Geometry drawn with plain AutoCAD commands on the custom layer is not part of the panel’s data, so it cannot reach the exported file. If such objects change a panel’s structure or geometry, redraw them with the ConstructiVision commands — or make sure the firm gets the panel book and plans showing them.

  • Export follows the drawing. The data files refresh when a panel is confirmed with OK — if you revise a panel after sending files, send the refreshed files (and see Track revisions for recording why the panel changed).

  • The engineering itself happens at the firm. The heavier background — crane planning, rigging geometry, brace-anchor design — lives in the field guides under Lifting and Rigging Details.
