Our friend came back from holiday and (s)he is up to something rather interesting… here – so let’s see…

God save the Queen – Under heavy Manners

Oh AutoCAD – sometimes we have to use it, in this case because the architect to the project where we provide the structural model uses it. Insult to injury – it’s AutoCAD architecture.

And the Queen – AutoCAD is clearly aging, and in our opinion the “Architecture” part is still a haphazardly attempt to achieve something even the Court of Autodesk might have forgotten why it is there.

Nonetheless – it is there and we have to live with it and make the best out of it.

So here is the workflow which turned out to be wrong – a step-by-step guide how not to use AutoCAD Architecture files as a backdrop in your BIM. and if you really need to – avoid the trap…

Step 1 – open the DWG and check:


Look at the door opening and try to remember how it looks like. Now we look at it in 3D (which takes AutoCAD some time to switch to – like 2 minutes plus…)


Its AutoCAD Architecture – we have 3D objects – hurray…

But now – due diligence – we Wblock out the part of interest to make the DWG more digestible for Revit. Using Wblock has been our standard practice to clean up DWGs for use in Revit – until this happened:


Where did the wall opening go? Got lost by Wblock.

After some research we found the way – first nuke AutoCAD Architecture and make it straight AutoCAD again – the command is AECTOACAD or -EXPORTTOAUTOCAD – this sends all AutoCAD Architecture objects to the bin (where they belong) to and leaves you with a fairly clean simple AutoCAD DWG…


Now you can clean up the resulting file to your hearts content and Revit will be happy when you link the DWG.

A happy Revit and – Life is good…

Be careful what you wish for…

Revit 2019 is great – the new feature of levels in 3D views is great – see:


However – if you upgrade a Revit 2018 file and switch into a default 3D view you might see the following:


And the culprit sits here:


The level naming – apparently Revit gets kind of nervous when level names contain hyphens or double hyphens – like “or “…

Renaming would not resolve so there is more to be figured out – stay tuned…

Wow, the engine is really load…

This is a great find – from our creep in the cellar. Now Revit really plays well with OpenBIM… sort of…


Some eye-candy


You got to know the tricks and… – Life is Good

It’s been a long time…

…long lonely, lonely time…

It’s been a while since our last post – there are reasons – we sort of got thrown under the bus by an interesting problem we are still working on.

Here is the model:


Partial model in order to preserve IP on the design

The challenge: create finishes on the walls derived from a parameter in the room:

The Dynamo:


All credits here to Peter Kompolschek.

Here vis the Python:


Again – credits to Peter K. with adjustments done by LRCZ.

The result:


Alternative approach – pure LRCZ stuff:

The Dynamo


The result


Similar results, the latter needs more work to get the finishes joined to the base walls – so stay tuned.

Life is… good…

Our best friend…

…has something to say here.

And I need to mention that I like my project looking like this:


Actually looking like this:


Me neither – and that makes life good…

Living in vain…

The emperors clothes – let’s try to clad columns in Revit using Dynamo.

Here is the workflow:


And here is before:Capture

And after:


Happy to share…

And life is now good…
