A Pattern language

April 1, 2018

We have a scaffolding here:

Noname

We need anchors to fix it at a checkerboard pattern – every second element in a story…

The Dynamo behind it is like this:

If you are interested – let me know… Dynamo here.

Movie times…

March 31, 2018

We put stuff on YouTube:

Place Elements.

Change Parameters in multiple Elements.

Change Parameters in a single row

The piece de resistance – propagate changes..

Propagate change in an assembly..

And finally – a 20 minute Dynamo – just move it all to create a corner – to be demonstrated in more detail

Move elements.

Not too bad for a Saturday afternoon…

And life is (almost) good…

Win through being cool…

March 31, 2018

Well, sane people enjoy holidays, sane people enjoy weekends, sane people… people with a condition described as morbus dynamoensis do Dynamo at those days.

But the stuff we did today is too cool not to be shared. And – other than usual – we won’t walk you through all the Dynamos – instead we invite you to send a message if you are really interested in how the stuff works.

Let me just show you a little teaser – here is this complex scaffolding assembly – constructed with a Dynamo script.

Noname

Note the line on the top left end of the structure. And remember that all the elements are still single parts.

First script will move all parts along the line:

Result:

Noname

And after selecting a single element in the scaffolding:

Noname

All moved. Note the detail:

Noname

As said above – this is just a tease for a variety of scripts to follow. You are interested? Send us a message…

Some more stuff…

From here:

Noname

To here:

In a single step:

The Dynamo is here:

More to come the upcoming days. And life is (almost) good…

What’s inside the box?

March 17, 2018

We recently got the following inquiry: there is a model consisting out of walls, beams, columns and floors.

All of the structural elements are made out of concrete.

We want to draw a random box and get the exact amount of concrete for structural elements by category that is within the box. If an element is partially cut by the box, we want it sliced by the box and the part within the box added to it.

Here is the Dynamo that does exactly that:

Let’s dissect that:

Noname

Here we get the user input – the box and the category of elements to take into account

Next we got to do a clash detection between the elements collected and – here I need to emphasize how great I find Bimorph Nodes – the performance difference is dramatic.

Noname

Now we check if elements are structural:

Noname

Then we pull the geometry of elements, cut them by the box and pull the volume

Noname

And – to make things snazzy we try to visualize that in Revit and Dynamo:

Noname

In Revit we do that by using the following nodes:

Noname

It honestly does not show too much – that’s why we use the Watch3D node as a proof of our results – here we can see that the elements are cut back by the box:

A quick one…

March 4, 2018

Category – 50 seconds Dynamo. It was not the greatest day of days today, lot’s of work and the server decided to do a Windows Update which basically consumed modt of todays productive time.

Nonetheless, jumping into preparations for a new project we started to lay out the grids and lo and behold we wanted to be clean and start with Grid 1 vertically and Grind A horizontally.

At Grid one we got the infamous warning:

Noname

The only problem was – Grid 1 was nowhere to be found in the project. So we had a choice of 2 – searching for half an hour to find the mysterious Grid 1 or building a Dynamo – in 50 seconds.

Capture

Done – Grid 1 is nuked out of the system and the name can now be reassigned. That’s essentially what I like about Dynamo, quick and easy stuff.

Life get’s better…

We still have a long way to go…

March 3, 2018

Another song title – who’s the first to name artist/album will get a present. Nonetheless, let’s get to the issue at hand.

Crunch time, projects coming in, and this week we had two IFC based collaborative ones. Finally real BIM!

The lay of the land is that we need to take these architectural IFCs and develop our structural construction drawings around them.

Number one – a nimble but still challenging project – adding a carport and garage to an existing structure and the IFC we got looks like this at first glance:Capture.PNG

Hmm – not perfect needs a bit of massage to work right but then again good enough to put the structural information in there and produce some sharp looking documents to communicate with construction…

Capture.PNG

Case closed on this one.

Next one looks so sharp in the IFC viewer:

Noname

But then again in Revit – outch – evil error message:

Noname

And the result in Revit

Noname

 

Ground floor is missing – so I call for help and Peter Kompolschek came to the rescue – he found the bug in the IFC file:

Noname

Following the advice I went into the IFC with a text editor and looked at line 2338 to eliminate the extraneous dot – like dot… a dot for xxx’s sake

Noname

And really – after eliminating the extraneous dot we got:

Noname

That is looking better…

But – as the title says – we still have a long way to go to make this happen in a way that is straightforward for everyday BIM users.

Credits to Der Architekt – Peter Kompolschek for debugging this.

And life is – getting better, inch by inch…

Hair of the dog…

February 24, 2018

It has been a while, flu, personal loss, many things but still there is something to share.

Don’t we all love Revit schedules and the fire drill when we need to put them into an Excel for downstream use. Fret no more – there is a simple Dynamo to dump all the schedules in your project to Excel – it looks like this:

Super simple it seems – the key is in the Python script there which looks like this:

This will dump any schedule in your project (Be sure what you wish for…) onto a location of your choice…

Excel Sheets… that’s works for me and life is good…

The joy of using a pressure cooker..

February 9, 2018

I admit – i (sometimes these days) like to cook – and the pressure cooke is a childhood memory…

610Gh2-UW6L._SX355_

So – now there is this project that I am not supposed to talk about but it is a pressure cooker of sorts – only bigger and we need to model a perfect structural model for some interesting analysis.

So our pressure cooker looks like this:

untitled.19

And the challenge was to auto-join all walls to the floor plate above to create a clean analytical model:

Noname.png

And that is a 50 second Dynamo – probably the first one I wrote that worked untested – take a look:

Capture

What we do here – first we select the walls and the floor above in Dynamo. We analyze the categories and filter for walls and floors:

Noname

Then we join using lacing longest:

Noname

Element.JoinGeometry is from the Clockwork package.

If you want to go hardcore and not use custom packages – this is the relatively siple Python behind it:

import clr
clr.AddReference(‘RevitAPI’)
from Autodesk.Revit.DB import *
from System.Collections.Generic import *
clr.AddReference(“RevitServices”)
import RevitServices
from RevitServices.Persistence import DocumentManager
from RevitServices.Transactions import TransactionManager

doc = DocumentManager.Instance.CurrentDBDocument
items1 = UnwrapElement(IN[0])
items2 = UnwrapElement(IN[1])
i = 0
booleans = list()
TransactionManager.Instance.EnsureInTransaction(doc)
for item1 in items1:
    try:
        JoinGeometryUtils.JoinGeometry(doc,item1,items2[i])
        booleans.append(True)
    except:
        booleans.append(False)
    i += 1

See the writing on the wall…

January 28, 2018

Doing Revit families is fun – dong complex Revit families is even more fun but then you need at mit of the special Spice to enjoy it…

So – my family with nested Structural columns works fine and it flexes nicely… in the Family Editor environment…

Noname

some parameter change

Noname

Bon – it flexes as expected…

Noname

Once loaded into a project document – boy oh boy – this does not look pretty:

Noname

And WHY IS THAT  you might ask – rightfully so… seems that the issue is buried in the structural column family…

Noname

This upper level is – IMHO opinion – the havoc… we here at LRCZ rebuilt the column totally new without the upper level datum and not…

Life is good…

P.S.: we understand that this topic is a rare special phenomenon but for details – PM me…
