Design Options - Delete Sheets and Drafting Views via Accept Primary

I was talking with my friend and former co-worker, Jon Rose, who is the BIM Manager at Devenney Group in Phoenix Arizona. He asked about something I was not aware of, so of course that means it requires a new post here!

The issue: Drafting Views were going to be deleted when accepting a Design Option in Revit.

Turns out Drafting Views and Sheets can be associated with Design Options. I knew schedules and all other views could do that as the content presented then changes based on the option selected. I will even be spending some time presenting on this topic in my MEP lab for remodels and alternates later this year at BILT-Eur 2018 in Slovenia. But Drafting Views and Sheets  do not change relative to a Design Option.

This post will cover the 'how and why' as I understand it!

As you can see in the image below (click to enlarge) that both Drafting Views and Sheets can be assigned to a Design Option (via VG or VV).

Exciting News for AEC from NVIDIA at SIGGRAPH 2018 - Quadro RTX Series

At SIGGRAPH 2018, NVIDIA's fearless leader and entertaining guy, Jensen Huang, announces a new and improved line of Quadro graphics cards; Quadro RTX 8000, Quadro RTX 6000 and Quadro RTX 5000 due to ship later this year!

These cards bring to market, the new VirtualLink, single USB-C connector, to simplify and improve Virtual Reality (VR) and Samsung DDR6 memory. The new line also boasts direct support for real-time ray-tracing via new RT Cores and accelerated AI via new Turing Tensor Cores.
"First implementation of ultra-fast Samsung 16Gb GDDR6 memory to support more complex designs, massive architectural datasets, 8K movie content and more."

Our friends at Autodesk are working with NVIDIA to leverage this new technology. I am guessing...

Revit 2019 Installation Error - You cannot install this product on the current operating system

Pending Windows Updates often causes issues with installing new software. A lack of updates can be an issue as well. Yesterday we had an issue with a person trying to install Revit 2019 -   getting the error shown below.

Turns out there was an error in...

Modeling a Historic Stone Building

Modeling existing buildings can be tricky. I have a couple of techniques to share about modeling this existing public park building. As you will see, this is a work in progress.

To represent the stone walls, there are two basic options. Make a repeatable texture from a photo of the wall, or just use a photo of the wall. Check it out...

Product Review: Hypar

I had a recent web-based meeting with Anthony Hauck, and Ian Keough, both of the newly formed Hypar. Before I talk about Hypar, I want to make sure you know who these two guys are...

Anthony Hauck was with Autodesk for 10 years and at one point was head of all Revit product line development and in his most recent role headed the development of generative design among other things. I've crossed paths with him many times over the years, at AU and RTC/BILT. As well as most recently when LHB hired him, post-Autodesk, to give a web-based pretension on generative design. He is a great and passionate guy!

Ian Keough is, well, the father of Dynamo. For the past 5.5 years he was also with Autodesk. He was also involved in some interesting BIM360 Field development. Here is a 2014 interview on the origin's of Dynamo you may find interesting: Meet Ian Keough, Dynamo’s Papa. I still find it interesting how things have evolved from what the Revit founders thought regarding user programming in Revit, as I previously wrote about here: Revit User Programming - Not Originally in the Cards. Clearly Ian had a different vision, and it has been widely embraced!

Much more could be said about these two I am sure... but suffice it to say this is truly a dynamic-duo from which great things will emerge! See what I did there:)

So what is Hypar? Here is the concise description from their...

Thermal Resistance in Revit plus Related ArchDaily Article

I read an article the other day from ArchDaily on calculating the thermal transmittance of a wall (see link below). It occurred to me to write a post on how Revit can calculate thermal resistance - R-value - of materials and assemblies... here it is.

ArchDaily article:
How to Calculate the Thermal Transmittance (U-Value) in the Envelope of a Building

By way of comparison, let's look at the table "Calculating Assembly Wall R-Value" from ColoradoEnergy.Org found here:

*This image is posted by permission from Randy L. Martin

The referenced graph has a column calculating the stud-only condition and another for insulation-only, filling the 3.5" space in the wall. Let's look at each condition in Revit:

Stud-Only Calc

If we open the residential template that ships with Revit, we see the R-value listed for the wall type Exterior - Wood Siding on Wood Studs. R = 8.30

However, the chart is dealing with a 2x4 (3 1/2") stud, not a 2x6 (5 1/2") so let's change that in...

Revit for Interior Designers Presentation by Ceilidh Higgins

Ceilidh Higgins is a a talented and prolific Australian interior designer, blogger and BILT-ANZ committee member. She recently did a presentation at the BILT-ANZ (2018) conference called: Inside Out – Implementing Revit for Interior Design Teams.

I've known Ceilidh for a few years now, and while I was not at the conference I heard the presentation went well. I had a chance to review the slide deck before the conference, I reached out and offered, and was happy/honored to see a slide recommending my Revit book for interior design! I love it when my peers review my presentation materials and manuscripts, so I try to do the same occasionally. I did not have too much to offer/comment on as the presentation was solid:)

I wanted to share a link to her post about the presentation, which includes her slide deck:

Be sure to follow her blog, The Midnight Lunch, which covers "Collaboration on the practice of interior design, architecture and multi disciplinary consulting."
