To do this i quite often use a combination of slab object and roof object, use a single sloping roof object with the correct fall/height above the slab object, then use solid element operations to trim the sloping underside of Roof to the flat top of the slab, as long as the materials are the same this should look correct in section.
Personally, I model all Flatwork (sidewalks, garage slab, paito...) as Roofs.
Easy to adjust the slope
Use of the Level Dimension Tool/Gravity Tool
Ctrl-Click function for perfect intersects with different slopes
Interactive Schedules for Control and Expansion joints - you can designate the edge of a roof plane and Schedule it. Just change the name of the caption in the Schedule to Expansion Joint or Control Joint - from one of the roof edge types you assign. 🙂
To get those slopes in the corners at the front of the garage you will want to have the roof pivot lines oriented perpendicular @ a 45
You have water traps at B, C, and D. Not enough to bother with perhaps ?
Hi guys, I tried either roof or mesh tools for sloping slab. For me, it seems mesh is easier to understand. Anyway, thanks so much for giving quick response and help for a new learner, it's so helpful here
