If you already use a building model
Schedules, types and sheets, set beside the register, take-off groups and pages here, and the one big difference: there’s no model.
In a model, a quantity is read out of objects somebody built. Here there are no objects: a quantity comes from lines you trace on a drawing, at the scale you set. The ideas still line up well.
- A schedule
- The take-off is the schedule: one row to a group, with what was measured, what you allow for and what to order. The register lists every measurement behind it, filterable by type, group, location and page.
- A type or family
- A take-off group is the nearest thing: a named line of the bill (Verge flashing, Rooflights) with its own allowances, stock lengths and price. Every measurement you assign to it adds to the line.
- Sheets and views
- A drawing here is a PDF, and a page is a sheet. Each page has its own scale, because sheets of one set are rarely all at one scale.
- Revisions and clouds
- A revision cloud is a markup tool. Compare is the comparison of two revisions of a sheet.
- A quantity from the model
- Here it is geometry × scale, nothing else. A figure is never read from text on the drawing, so the same two clicks always give the same number, and the bill can show its working.
- Phases and filters
- Layers show and hide sets of markup, and the register's filters narrow what’s listed. Neither changes a total: hiding is for looking.
