Lay down and die, goodbye

Who remember The Nazz? I took the song title for today’s post – seemed like an odd fit.

Haven’t we all seen it before – we get to work on a project that is bloated with parameters that nobody cared to fill in, are irrelevant and just eat up screen space – and model performance for sure…

Noname

So – the objective is to create a script that checks all parameter bindings, then checks all elements of bound categories and then checks if there is any value set in the paramater in question.

Let’s start: Here we get the parameter information:

Noname

The python behind this looks like this:

With this construct we gather Parameter Name, bound Category and Parameter ID

Now, a little bit of an UI

And the finished result:

And life is good… For the script – ping me…

All we ever wanted was everything…

I want to flatten a list in Dynamo from the right to the l;eft – not the left to the right.

OK – OOTB Dynamo will allow you to use the List.Flatten node to flatten a list for a specific amount.

dontwant

But what if you don’t want to have it that way, you want to have the list flattened at the @L2 level 1nstead of the @L4 level.

First attempt – use a negative number at the amt input of List.Flatten

Not working – the list completely lost it’s structure and is now flat – like a smorgasbord…

In order to get to the desired effect – kudos to Ben Osborne dynamobim.org – you got to do this:

And life is good…

 

Bela Lugosi just died…

So – for matters explained further in the coming days – I was on the search for some manufacturers content to fill in a gap in my BIM…. I ended up on the Schöck website and after frantically clicking all options I ended up with

Capture

Duh… no Model, and even getting the lame 2D requires a PHD…

Is this BIM?

Yours truly (and yes, Herr Schöck, call me if you want to make it right) Manufacturers Content is Fake – IMHO

Yours truly grumpy ole’….

 

Always Crashing In The Same Car

OK – another song another story – let’s talk clash detection for minute. Aim is to clash walls from one file – basement of a rather handsomely large structure with sitework.

Files are OpenBIM and Revit and you know what, so first approach was to use IFC based tools to figure out what (t** f***) is going on.

Take Tekla BIMSight as an example – what you get is:Noname.png

Oh well – now I know more – does that help me how to track down real clashes?

After a few experiments in Navisworks I came back to good ole’ Revit, probably because I know the tool best.

So – how we get the IFCs into Revit? ArchiCAD to the rescue – their Export to Revit nails it (don’t even bother to directly open those IFCs in Revit – but that is another blogpost so stay tuned). Workflow is to open the IFC in ArchiCAD and the export to Revit – cool isn’t it (caution – sarcasm ahead)

Noname

By that workflow two Revit files got created – so the smaller one gets linked into the bigger one and – bang – here we are, visibility settings adjusted:

Noname

Now we put Dynamo into place

Noname

Next we have a dedicated 3D view of each clash to apply human eye scrutiny

Noname

And life inches in to be good – next step is to actually get the clash geometry to clean up false positives but that is stuff for some other day…

Brown Paper Bag

As you might agree – stairs in Revit as – sometimes – a bit tricky…

Capture

Now that we have in-place stairs, we could amend a situation like that utilize them but – wouldn’t it be greater to have a loadable component family instead?

Here is the Dynamo that does the magic…

And here is the result:Capture

Looks better – now here is the family:

All editable geometry glory…

And life is good…
