Quickly familiarize yourself with the knowledge points of BIM "Modeling Application Technology" in 2021
Introduction "Modeling Application Technology" is a subject that will inevitably be tested when obtaining a BIM certificate, so we need to focus on it, master the necessary test points of this subject, formulate a review plan, and carefully review each test point. To master the important and difficult points, here is a summary of the knowledge points of BIM "Modeling Application Technology" in 2021. Candidates in 2021 should quickly collect it.
1. Family: loadable family, system family, built-in family.
2. Category-Family-Type-Instance.
3. Baseline primitives, model primitives, and view-specific primitives (standard and detailed drawings).
4. Four basic file formats: ret, rvt, rft, rfa
5. Revit provides "import", "link" and "export" tools, which can support CAD , FBX, IFC, gbXML.
6. Options bar, ribbon, property bar, project browser, and drawing area.
7. Customize the quick access toolbar: open, save, synchronize and modify settings, abandon, and redo.
8. SHIFT to rotate, VIEWCUBE to switch, and ZR area to zoom in.
9. Zoom tools: zoom in area, zoom out twice, zoom to match, zoom all to match, zoom drawing size.
10. Wireframe mode: has the worst display effect and the fastest speed.
11. "Real" is related to the "Appearance" option parameter, which is used for the material texture when rendering primitives. Ray tracing works best.
12. Element selection in Revit: click, frame selection, and filter selection.
13. If multiple graphics elements overlap, press "Tab" repeatedly. "Shift+Tab" cycles through elements in reverse order.
14. Grid type attributes: axis middle section, end section width, end section color, end section fill pattern.
15. Revit provides six disciplines: architectural, structural, mechanical, electrical, bathroom, and coordination. Non-structural elements such as "building walls" and "building floors" will be hidden, but "wall trims" and "curtain walls" will not be hidden.
16. How Revit creates beams: beams and beam systems.
17. Bar foundation belongs to the system family.
18. Revit provides architectural walls, structural walls, and facade walls.
19. There are three basic styles of Revit architectural templates: curtain wall, exterior glass, and storefront.
20. Basic parameters: material, dimensions. These parameters can be modified according to the needs of the project.
21. Revit plane sketch drawing components: floor slabs and roofs.
22. Roof creation methods: surface roof, trace roof, stretched roof.
23. Edit the railing position alignment: starting point, end point, center, and expansion style matching.
24. Create a sketch of the ramp: steps, boundaries, and risers.
25. Terrain creation methods: directly place elevation points, import contours (DWG, DXF, DGN), and import point files in civil engineering applications.
26. Revit three-dimensional view: orthogonal and perspective.
27. There are three ways to open the "Graphic Display Options" of the view: Visual Style - Graphics Display Options, the small triangle of the view, and click the Graphics Display Options in the property bar.
28. For color control, you can choose "Keep" or "Black and White". It is better to choose "Keep".
29. Modification principles for collisions between water pipes and other majors: the top of the wire bridge, the middle of the air duct, and the bottom of the water pipe. Meet the requirements: the pipe height is 200 meters from the bottom of the beam. Save space. The gravity pipe collides with other, other should be modified: pipe offset 200.
30. Vertical alignment: middle, bottom, top.
31. Pipe fittings can be placed in plan view, elevation view, section view, and three-dimensional view.
32. Pipes are single-line in thick and medium sizes. Fine lines are double lines. The duct is single-line in coarse and double-line in medium and fine.
33. Pipe types: radius elbow/T-shaped tee, radius elbow/joint, mitered elbow/T-shaped tee and mitered elbow/joint.
34. Preferred connection type: Set the default method of duct branch connection.
Default types of T-shaped tees: joint, cross, transition piece, multi-shaped transition piece, and union.
35. Set the "roughness" according to the air duct material, which is used to calculate the resistance along the air duct.
36. System-HVAV-duct accessories.
37. The setting of hidden lines is used to set the display of the intersection and occlusion relationship time between graphics elements.
38. Family is the basic unit of the project and the carrier of parameter information.
39. Principles for comprehensive layout of pipelines: meet in-depth design and construction specifications, rationally utilize space, meet construction and enclosure space requirements, decoration requirements, and ensure structural safety.
40. Comprehensive general avoidance principles for pipelines: small to large, use the gap between beams, local air ducts should be turned down at the intersection of wind and water pipes, all pipelines should avoid gravity pipes, and the low cost should be high.
41. Principles for the layout of shaft pipelines: cable wells, pipe wells, flue exhaust ducts, exhaust ducts, and garbage ducts. Each floor should be equipped with an inspection channel with a width of not less than 0.6M. Indicate the direction, diameter, elevation, and coordinate locations of different types of pipelines.
42. The benefits of Revit plug-in: greatly improve work efficiency, more accurate models and drawings, smarter models, and two-way exchange of information with external software.
The above is a summary of the knowledge points of BIM "Modeling Application Technology" in 2021. It is also useful information for preparing for the BIM exam in 2021. It needs to be mastered. I hope everyone can become familiar with it quickly. Regardless of the categories of commonly used BIM certificates, this subject is It is the focus of the exam and can also help us improve our skills!
