Let’s get physical…

These days Livingroomcraftz has been very busy on a particular project that also involved creating a physical model.

So – a little run down on architectural 3D printing:

These days you can choose between FDM (fusion depositing modelling) and SLA (stereolithography printing)

First option – FDM – creates a model by adding plastic layer by layer



Clean process, if the printer is set up correctly it is pretty hassle free

Large build volume

Hardware is getting ridiculously cheap these days


Level of detail is questionable

Material cost for a professional printer can be significant

Build time is long

Second option DLA resin printing



This is a < €500.– printer

Quick build time (1 hour/20mm height)

Superb level of detail (see below)

Material is dirt cheap


Working with potentially dangerous chemicals

Small build volume

A sample of what the print looks like


Yes – it does transparent – you can even get dental grade resin

But – that’s what you need


As you can see – it’s an Anycubic Photon S and – it’s fun to do stuff

However – given the different modelling styles you also need to adapt your modelling style before sending it to the printer – but that will be another post

Just a final picture of what stuff will look like…


And – did I forget to mention – life is good…

Fear is a man’s best friend

After some while of silence – here we are again. The title might be misleading – as usual – but substitute “Fear” with “subst” and we are talking.

Subst – a command going back in those days where DOS was the welcoming screen of your computing device.


So – in case all your Revit links on your office computer point to something like this:


But your current travel related setup looks like thisCapture.PNG

Note the drive letter change – no way Revit will reload the gazillion links without cumbersome re-pathing.

But here is the trick – command window and subst command – make the pathe on your laptop the same as on your office network and all will be good.

A quick hint:

Life is good… so good…

Our long time friend…

…found something.

And we do like Enscape a lot. Not to be misunderstood as promotion, it just works here as a tool to do our job well.

And life is good…

I can’t remember my own name…

(I think I’ve gone insane…) Another 90íes song title that come to mind but summarized beautifully the finding of the day.

Think coordinates – long ones. Think about geo-referencing your Revit file. Think about angles and coordinate precision.

Allow me to take you onto a ride – we start simple. In Revit we rig up a simple test bed such as this:


That’s the project units – now lets set up the project:



Basic – lets just add a dimension to the angle:


Now – to make it a bit of a challenge – let us apply shared coordinates to this:


And now let’s check the output after exporting it to DWG:


So far all looks good – here is a close-up measured in AutoCAD


Now let’s change those shared coordinates to something mildly insane – but Chinese Xi’an 80 system has insane long numbers:


Now lets see the result in AutoCAD:


If you look at the coordinates in AutoCAD you might see the difference


Source files are available upon request.

And for now – life is good…

On a faraway beach…

It has been a while since the last post but it had been very busy here at Livingroomcraftz. Which is good.

We got deeply involved with IFC lately, having the need to aggregate models coming fromm various different authoring applications into a common reference model. And that is where the Good, the Bad and the Ugly in IFC comes to the surface.

Challenge number one – working with large geo-coordinates. You take your Revit Model and add geo-referencing


All good – now you export to IFC with geo-coordinates on:


Still all good – now your IFC is geo-referenced


See here:


But what if you want to get a geo-referenced IFC back into Revit?

Lets try this now:


And the result:


An empty sea of nothingness – elements have been created but simply do not display


The reason for this is that – in a geo-referenced – IFC-file Revit will take the Survey Point coordinates as the Project Origin coordinates. Given Revit’s 24.5 or something coordinate limitation this is doomed to fail.

Alternatives? Let’s try the help of ArchiCAD:

Open the file in ArchiCAD


Using the bim6x plugin to ArchiCAD export directly to Revit


And the result in Revit is:


Getting there – life is good…

Touch and go

So let’s play a little game of Touch and Go – the client request this time was to create a Dynamo script that would do the following:

  • Allow selecting elements of various categories
  • Get all available quantities out of the elements
  • Display sums of quantities

Well here is the script:


Link to script here

So what it does is that it will prompt you to select elements in your model:Capture

And the result you get displayed in a Windows form:


Nothing too fancy but getting to the Windows form display is in a way a noble idea because it is just a few lines of Python – see here:


This is the code behind it


Simple – but elegant – and life again is good…
