1-3 sentences about what the article is

View Range: Cut though stem wall. For slab on grade cut through top of stem wall and above buck out (notched lowered sections for doors). Plan regions will likely be necessary but try and minimize their use by properly setting up the view range

• Floor slab: don’t show where you can reasonably infer the edges, otherwise floors in general should be transparent
• Structural Slabs as footings: show as normal footings (keep in mind footings are invisible on most other views)
• Similar footings: if footings (especially individual elements attached to posts) are hard to visually distinguish make them all the larger size, a single error could more than offset small concrete savings
• Showing posts: in all the posts families there should be an option to extend an invisible line down Through the cut plane so they display (only do it for posts on foundation elements and Not posts above, do not do it on posts with Attached footings) make Foundation Posts Extension Down equal to the stem wall height

• All standard dimensions and dimensions needed to form the foundation
• Dimensions and reinforcement of stem walls (defer as much as possible to typical sheet notes)
• Dimensions and reinforcement of footings (defer as much as possible to typical sheet notes)
• Slab note
• Tag shear walls
• Callout hold downs
• Flag details
