Beam System — generate roof framing from selected faces
Open BimSpeed.STR → Model → Beam System. Prepare roof faces and Structural Framing families with readable section-height parameters. A framing system differs from an individual beam or reinforcement design.
| Control | Use |
|---|---|
| Pick Plane / Clear | Pick roof planes in Revit. Clear removes the dialog's face list, not the roof. Check the selected-face count. |
| Family | Filters available beam types. Load a suitable family if empty. |
| Layer / row checkbox | Three physical layers: layer1 follows the main direction, layer2 is perpendicular and layer3 parallel to the main direction. Only enabled rows run; the reviewed default enables layer1 only. These are not CAD layers. |
| Row type | Framing section for that group. Inspect actual type dimensions. |
| Spacing | mm. Reducing 1200 to 900 should increase the member count for the same region; inspect actual instances. |
| Color / Select | Sets the group's display color; it is not material selection or a structural check. |
| Offset Z | mm. The reviewed stacking path negates a positive value to move downward. Layer1 is nearest the picked plane; layers2/3 add the heights of enabled upper layers. Check sections and sloped faces before a batch run. |
| Height parameter | The section-height parameter used for placement. Avoid a text/type-name parameter. |
| Save / Load Settings | Saves/loads tool configuration, not RVT geometry. Recheck family/type availability after loading into another project. |
| Create Beam System / Close | Creates from the selected faces/groups, or closes the window. |
Generate on one face first. Inspect plan and roof 3D, then select a member and verify type, length, slope, offset and spacing. Review differently oriented faces separately; selecting several faces does not prove continuity at their junction. Undo an incorrect run before changing inputs, and check whether repeating creates additional systems/members.
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
The installed Revit 2024 window was reviewed. No reference face was selected and no beam system was generated. Replace the initial project type with the intended beam section before practice. The central action button has no visible label in the reviewed UI.
The Vietnamese interface is shown in the Vietnamese guide.
