Get in the Swing…

A nice well documented workflow that our most beloved nerd worked out today… – find it here…

And life is good…

Before we call it a day – some eye candy…


Enscape makes things look cool..

And the day has been great…

Dearest creature in creation…

Holidays are play times – – and so we found the Autodesk viewer and started to throw models up in the cloud…

Nice – but why is my 250 mm concrete wall in Revit reporting 249.9940 mm in Autodesk Viewer…?


249.9940 mm…

A new years tip for #Autodesk – can we start calculate geometry in Revit in something else then decimal inches? It’s only the US, Liberia and Myanmar using this unit system. The rest of the world suffers from Revit rounding errors.

Then life would be good…

I cant remember my own name…

Madness – spot elevation madness…

Revit – as usual – something insanely mad – spot elevations in views bound to a tilted scope box…

Anybody following?


Red lines indicate the scope boxes…

The view looks like this…Noname.png

Now applying spot elevations – there are 3 different choices and 3 different outcomes…

First, no leader


Nah – German drawings do not look like this

Second: Leader and shoulder on


Nah, nah, nah – looking terrible

Third option – drumroll please – Leader on, shoulder off


Revit will never stop to amaze me in these regards…

And life is good…

Thank god it’s not X-mas…

IFC is the topic of the day – take a look. In any standard IFC viewer the file looks like this:


While in other IFC viewers it looks like this:


How come – let’s take a 3rd attempt at viewing the file:


And here is the culprit:


Now that can’t work – walls outside the Default Project are probably not a good idea..

Let’s take this a step further

The first missing wall has n IFC Id starting 6xx


The missing line though was here:


Adding wall 645 – and here we go


IFC demystified… and Life is good…

Hidden by the dashboard…

Sometimes things are in plain sight but we don’t see them… like – pun intended – Revit reveals…

Objective was to grab all reveals hosted in a wall and sum their length up and write the sum into a parameter of the wall.

So there areNoname.png

So we either have a single or multiple reveals in one wall. Now some Dynamo logic:


Let’s dissect this for once in a while since it took us some time to figure:


In Types reveals show up as wall sweeps – in categories > all elements of category they don’t show up at all BTW – so we have to take the reveals and work our way back to the walls

Which happens here – thanks to Copyright(c) 2015, Konrad K Sobon


And then the piece-de-resistance

List Group by Key and Math Sum – Magik (“k” intended…):


And the result:


And life of course is good again…

BTW – have you checked that reveals won’t subtract from the Wall area but do subtract from volume – kind of wired…

What the h… is it this time?

Something unusual – an AutoCAD (what ?!?) tip – but still noteworthy…

So we found ourselves in the position that we needed to compare 2 sets of PDFs – after long hours of getting the workflow right we settled on AutoCAD 2080 – importing the PDF from set A, overriding the colour, then importing set B to view the differences…

Which worked quite OK until, trying to select all entities in the DWG brought back – nothing.



So that is what we see after selecting all in AutoCAD


OK – all selected but Properties say – No Selection

After digging around I found this.

So – setting PROPOBJLIMIT to 0 we try again:


And all good – AutoCAD – oh boy…
