Formwork — settings and scope limits
| Control | Use, effect and verification |
|---|---|
| Active View | Limits intersection candidates by view; Run still asks for hosts. It does not select all visible hosts automatically. |
| Select Elements (link option) | The binding is IsSelectLink and switches picking to LinkedElement. Confirm the live label rather than interpreting it as ordinary host selection. |
| Draw Bottom / Top / Side Formwork | Choose generated face groups; contact regions can be deducted. Inspect each face in section and count output shapes. |
| Tường: gộp đáy vào thành (như cũ) | Legacy wall-area grouping; inspect FW_SIDE/FW_BOT before comparing with beam results. This label may remain Vietnamese in English UI. |
| Column / Beam / Floor / Wall / Foundation / Stair / Roof / Part | Eight host-category pick filters. Part means Revit Parts; each category requires its own case. |
| Run | Closes the dialog, picks host/linked elements and generates after Finish. Inspect warnings because individual failures can be skipped. |
| Help | Opens help without generating or recomputing geometry. |
| Add parameters | Enables custom parameter-list creation, rather than computing quantities. |
| Parameter Name / Add | Queue a nonempty, unique name. |
| Remove | Remove the selected queued name. |
| Create | Creates queued Text parameters on enabled categories; distinct from Area parameters prepared for FW_AREA/FW_BOT. |
| Warnings: ID / Description / Show | Inspect affected IDs; Show locates rather than repairs them. |
| Warning export / processed flag | Some warning dialogs expose Save and Processed; report export/marking does not prove geometry repair. Confirm the actual dialog variant. |
| Close | Closing can save FromworkSetting preferences; it does not save the RVT. |
| HOST_GUID / HOST_LEVEL / BS_HOST_* | Shape host metadata. Linked source RVTs are not written back. |
| FW_AREA / FW_BOT / FW_SIDE / FW_TOP | Read in project Area units and compare the same face scope. Distinguish Area from Text/Number parameters. |
Retained evidence: beam FW_AREA 11.026 = FW_BOT 2.205 + FW_SIDE 8.821 m². Other category/link combinations require separate evidence. Source mapping does not establish live entry/UI behaviour. Collapsed controls are not counted as visible UI.
Prepare parameters before reading Wall/Floor quantities
Select one host in Revit Properties first. If FW_AREA is missing, a visible formwork face or a closed dialog does not prove that the host received an area. An R24 run calculated Wall/Floor geometry but could not write the missing fields; that run is unsuitable for a host quantity schedule.
- Save an RVT copy. Under Manage → Shared Parameters, use your organisation's shared parameter file and the definitions below. Retain GUIDs already used by templates/schedules; do not create a second GUID with the same name to fix a missing binding.
- Under Manage → Project Parameters → Add → Shared parameter, select each definition, choose Instance, group Data, and the categories receiving the values. For Wall/Floor, bind Walls, Floors; include Specialty Equipment for generated formwork shapes. Type parameters cannot represent different areas for hosts of the same type.
- Reselect the host. Confirm the field exists, is writable and uses Area. Project Units control its m² display; do not manually multiply square feet into an Area field.
- Run Formwork on one small host with deliberate face options. Read
FW_AREAseparately on the host and each shape. Save and reopen the copy, then check the same host before scheduling an entire floor.
| Definition | Type / scope | What to verify |
|---|---|---|
| FW_AREA | Area, instance, host + shape | Total for the processed face scope. A shape value belongs to that shape, not the whole project. |
| FW_SIDE | Area, instance, host | Side area. For walls, check the bottom-into-side compatibility option before comparing totals. |
| FW_BOT / FW_TOP | Area, instance, host | Bottom/top where the category path writes those fields. A zero does not prove an absent face when the Wall path writes only total and side. |
| AREA | Area, instance | Optional parallel total if used by your template; compare with FW_AREA on the same host. |
| HOST_GUID / HOST_LEVEL / HOST_TYPE_NAME | Text, instance, shape | Host identification. Do not add host totals and shape totals together. |
The Add Parameter tab does not replace Area preparation. Enable Add parameters, enter Parameter Name, then Add to stage a name. Select a row and Remove to discard it; Create creates Text parameters from that list. It does not map FW_AREA to another name or recalculate quantities. Opening the tab alone creates no verified quantity fields.
Linked hosts cannot be written back into their linked RVT from the current model. Read the shapes created in the host document, with their host/link identification. The new native Wall/Floor evidence does not verify the linked branch.
