09.7 House Extension - Section Annotation

Section with No annotation above


Section with Annotation above





Generally sections and detail views have the most 2D work so once we finish these theres not much more to go. In this post we convert the defalt revit section into a more presentable section, do to this we add;
- Wide Dashed drafting lines for DPM and DPC
- Repeating detail for block work joints in section
- Filled region for the foundation trench infill(connects with the hardcore in the base of the floor slab)
-Learn how to import autocad hatch patterns that are not available in revit, some good download sites are http://www.cadcorner.ca/hatch.php and http://www.autocadhatch.com/
- Wide drafting lines for the steel lintel
- Thin drafting lines for the X inside of the cut ceiling joist and rafters
- Spot elevation makers
- Insulation tool for roof insulation
- Splitting the section marker lines
- Text notes and Leaders

Note: don't move the section markers in plan after you place the annotation or it will get out of sync with the 3D objects ( the last thing i show in the video)

Below is the text notes that i use in the video, you can copy and paste them from here if your following along,
Warning you must proof read them, check they comply with the latest local building regulations and all structural specification are check by your structural engineer, i don not take responsibility if you reuse these notes on a live project.
