05.3 Concrete cast insitu element - Video Tutorial Part 2

Please view 'Part 1' 05.2 Concrete cast insitu element - Video Tutorial  first in the previous post, then view this video for the extra context to the detail, note the cool trick a the end of video 2!



05.2 Concrete cast insitu element - Video Tutorial


Enclosed is the first part of 2 video tutorials for the concrete cast in-situ detail, the first part is the main detailing, the second video is just adding some context to the detail to allow you see the full project detail. One note which i didn't mention is that there is a requirement of an L-shape metal angle to support the brick above the curtain wall storefront, this metal angle should be fixed back to the concrete beam with chemical anchors or bolts that are already cast into the concrete.

Profiles and Their Parameter in a Project


This is a quick video about a question one of my followers Steve had asked about how do you modify the parameters of a profile that is attached to the gutter family within the project environment? This is based on the curved roof tutorials i done a couple of weeks ago. The secret is that to modify the parameters you actually need to search in the project browser under 'families', then under 'profiles', then expand your profile name and on the type name right click and enter the properties, this will now bring the parameters available within the project environment. See video below for more details.

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.

Revit 2011 - Upgrade all your projects

Revit 2011 is just released. I recommend that upgrade all your office projects and then update the materials in each and then turn on the realistic materials and start making nice office presentations/marketing material. small clip which I did this morning.

04.3 Curved Roof Detail - Video Part 2 of 2

Curved roof detail - Part 2. This covers verge board detail using fascia tool, slanted roof shape(plan view) when roof is created through section view and custom verge required for this slant in plan view, also some minor 2d work.

Introduction for new blog viewers

Hey all,

Thanks to Gregory Arkin over at Bimboom, Join the REVITlution,( for reposting one of my tutorials on his blog, my following has doubled in one day and my site hits went from a high of 34 views a day to over 200. Thanks Gregory!

I also thought that I'd need to re-explain my theory concept and how my blog works otherwise you'll have to go to one of my first posting to figure out what's going on. Due to Blogger always putting the last post at the top it may look like the chapters are backwards. In most case I'll take one detail at a time and split it into 2-3 subchapters, the 1st subchapter will always be breaking down the detail and analysis, this will be followed by a video tutorial and there may also be a 3rd subchapter on advanced modelling or 2D work. I recommend that you read the Analysis text blog 1st before watching the video (it will make more sense of the video and some of my assumptions) Below is my breaking down the detail theory.

Take an existing cad drawing or a quick sketch on butter paper or scrap paper etc. After you sketch your detail up, you then work with a simple 5 column table (which can also be a sketch).

1st step - Draw detail and annotate it
2nd step - Mark a number beside each annotation on your sketch
3rd step - Fill out table

Column 1 - #
This is the number that links the number on the table with the number on your detail.
Column 2 - Brief description
Write a brief description of the object
Column 3 - 2D/3D
Review the brief description and consider wheather you think you should model it or draft it. if the object will be seen in more than one view type it should probably be modeled.
Column 4 - Modeling type
Decide what revit tool you will use to create the proposed component, is it a floor or a wall or a custom generic model family, etc.
Column 5 - Family type
After you decide the method of modeiling then figure out what family type within that revit tool your going to use, this also help you decide if you need to create a new family that is not already in your model or template.

04.1 - Curved Roof Detail - Analysis

This detail is on a curved roof; consisting of insulated metal roof panel (curved) on structural roof beams/purlins/girder’s (whatever it’s called in your region of the world). It has an eaves junction with an external wall and requires a profile gutter (that matches the roof manufactures detail or is a commonly supplied element by the roof manufacture) and has a few other elements such as wall plates, cavity closers, fillers etc. The other cross section show the verge detail in which the side of the roof panel meets the wall, this joint needs to be covered with a verge board or special flashing piece. Below are the 2 initial sketch sections and a list of objects I think are in the detail.


The next post will be video modelling of this detail, will try have it posted by the end of next week.




Join geometry to cut geometry...Huh!

I had some good comments on my ‘Concrete Basement detail video’ a couple of days ago about the method of unlocking layers in walls and extending them down, the other option which I completely forgot is the simple ‘join geometry’. If done correctly it will actually delete or cut the wall to get a similar effect to the method of extend wall layers. Note it will only work in certain situations not all. Below is a quick video showing 2 situations on my previous post. The join geometry will work for one detail but not the other this because the detail of one is too complicated for the ‘join geometry’ and there is not enough objects to continue cutting the wall. The other detail is perfect for this as it is a simpler details and the wall and cutting slab stop on the same line.

Any other suggestions or tip please forward.
