Revit Shadow study export and using Phases for Presentations

A couple of interesting presentations I came across.

Solar/Shadow studies

by the Revit Kid: Revit Tutorial – True Solar/Shadow Studies

A couple of interesting things he did in this video that I didn’t know about:

1/ Using Camera to make a plan orthogonal view (instead of perspective, thus being able to show windows full height instead of the slice with the scope box.

2/ That you can export an AVI of a sun/shadow study for a day/period to send to a client to show level of light penetration into a building at a particular time (or solar shading, if that is your bent.

This must have come out around 2017 as I’ve never seen it before, but its a simple, handy tool. I like it

Using Phases for presentations

2017 0517 SeaRUG – Leveraging Revit for Presentations from about 20 minutes to 29 minutes in the video below.

Basically, you make another phase, in this  example I have used “Pres”

In the Phase Filter, Override New & Existing Phases and for Demolished (and any others) put to Not Displayed

Then in Graphics overrides tab choose a material for Existing- in this case I have some turquoise material, and if you had lots  of glass in the new phase you could put the material as Glass.  So New & Existing phases are overridden  by the material selected.

I then rendered this.    A bit fuzzy, but no cloud credits to render

I think you could do some messing around by shunting things to different phases. You would not do that in your production model, but you could do it in a copy set up for quick presentation to give a general idea of the model. You could do it all white with some shading, like a cut out polystyrene physical model.

A nice quick and dirty process. Good for setting up to focus on a specific element of the building.

I actually disd a similar thing with walls that Structural were going to make SHEAR walls by colouring those RED so they stood out and showed their impact on the existing building. A useful tool to take to coordination meetings  when you wish to highlight an issue as it clearly showed interface between the elements you want to highlight.

The 3D PDF is great for capturing stuff like these at a cirtain juncture in the project. It allows for 3d exploration of the model and is an INSTANT IN TIME  in the project. You cann then turn this colouring off and move on with the project.

Filters & Color Splasher

Another way to do this is to give all  Categories a numeric parameter say CLASH ITEM. You give each specific item a number 1, 2, …25 etc and you splash the colours , or setup a filter , so that you colour the 2 items that are causing Clash problems different colours so that they are easy to highlight. I must admit I find color splasher far quicker and easier to use than Filters as the pop-up box is in the same screen as the model and small enough not to get in the way.

You could use something like COIN auto Section Box to create a 3D view of the specific area, then send it to a 3D PDF.

3D PDF’s are good to make a record (or a simple screenshot) so that these items can be passed around to other consultants to highlight the issue.

End comment

A couple of techniques I will try out in the future.

The Phases one is quick, and easy. But I think you’d need to make a copy of your model so you can adjust a few things between phases for effect and you wouldn’t want to be messing with elements and phases in your main model.

The Shadows is a good one to send to clients to talk about sun penetration into buildings. Kiwi’s love sun but its good to indicate where there may be overheating issues.
