Section Manager — create section types rather than section views
Open BimSpeed.STR → Model → Create Section. Tabs are Beam, Column, Foundation, Slab and Wall. Here a section means an element type, not a Section View from an Elevation. Creating a type does not place instances.
| Control | Units and effect |
|---|---|
| Beam / Column Family | Selects the family whose symbol is duplicated. It needs compatible b/h or Width/Depth parameters; a 250x450 name alone is not proof of dimensions. |
| Prefix / Suffix | Builds the type name. Distinct types need distinct names. |
| Add | Adds a proposed row, without yet creating its type. |
| Fixed Size | mm, one dimension for Beam/Column naming. |
| Step Sizes | Listed sizes in mm, such as 200, 250, 300; each value creates a proposal, rather than specifying an iteration count. |
| Format | Name template: {FixedSize} and {StepSize} for Beam/Column; {StepSize} for Foundation/Slab/Wall. Preserve token spelling. |
| Generate Multiple | Populates proposed rows; it does not establish that RVT types exist. |
Each tab has Section Name, status and per-row Create. Foundation/Slab/Wall also have Thickness (mm): use this explicit value rather than an unrelated number in a name. The input converts mm internally; do not enter feet.
Delete Selected Sections removes selected proposal rows; it is not a substitute for deleting types in Project Browser. Create Selected processes selected rows; Create All processes a broader set, so review names and thicknesses first. Close exits.
For Beam/Column, an existing name can trigger updating its b/h from the name, rather than simply skipping it. That can affect all instances using the type. Existing Foundation/Slab/Wall types are normally retained/reported; inspect Type Properties before deliberately changing them. Check compound layers and materials when thickness changes.
Create a newly named 250x450 beam type and inspect its actual Type Properties. Create a new 200 mm Slab Type and inspect total thickness/layers. Expanding a size list from 200,250 to 200,250,300 requires a real additional type and correct status; proposed rows do not prove placed geometry. Undo unintended changes to used types, save/reopen, and verify in Project Browser. Place instances separately when geometry is required.
Practice input
Download the shared Revit 2024 column/foundation input. This educational file has four rectangular columns and one footing; it is not output from this article's command. Read the ZIP README/provenance and Save As before editing. It does not contain every roof, pile, link, Legend or dimension case; prepare the categories/grids/views/families required above. Screenshots on a real-project copy do not imply distribution of its private RVT.
Observed build and verification scope
All five Beam/Column/Foundation/Slab/Wall tabs were opened. Rows marked “Đã tồn tại” are existing types; types were not created/deleted during capture. Main labels switch to English, while row statuses still contain Vietnamese in the reviewed build.
The Vietnamese tab reference is shown in the Vietnamese guide.
