05.1 - Concrete Cast insitu Element- Analysis

'3D view Cut Section Rendered Perspective'

'3D view Cut Section Perspective' / '3D view isometric'

So the detail being discussed in this chapter will be on concrete cast in-situ elements that may appear to be complicated but can be done simply with a few different revit tools joined together. First I must note I owe Phil Read a beer for using one of his fancy handrails in my model, Phil if i ever meet you a beer is on its way!

Now to the detail, as before there is a 2D sketch of the detail and what i think is involved/or i want to be involved. The main thing with this particuler details is that the concrete element will have 2 down stand beams(one that is a arch), an upstand beam(lip or edge that holds the railing and stops rain water from spilling onto the facade), Concrete columns and supporting slab for the external walkway. There are some other element to give the detail context such as external walls, store fronts, inner slabs and floor finish, railing and sloped roof/floor on the external walkway. Lets look at the detail first and then i will overlay some colours so that you can see how i break it down into simpler elements.

Now that we've look through the basics, lets break down the concrete element into smaller pieces. You can see from the blue shade below the element i'll do be using a wall type, also by using a wall type for the arch downstand means that i can edit the profile of the wall and change the arch easily(higlighted by the light blue). Green is for floors, red is for beams, Yellow is for roof type. Note the tops and bottoms of the walls and also the floor edge postition(left and right), now that we know these we can draw the element with the correct outline or correct top and bottom offsets and quickly assemble the concrete piece, note all the materials should be the same so when you join them there is no line.

The next post will be the first part of the video tutorial.
