Fear is a man’s best friend

July 11, 2019

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.

Capture

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:

(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:

Noname

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

 

Noname

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:

Noname

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

Noname

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

Noname.png

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

Noname

Now lets see the result in AutoCAD:

Noname

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

And for now – life is good…

On a faraway beach…

April 14, 2019

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

Noname

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

Noname

Still all good – now your IFC is geo-referenced

Noname

See here:

Noname

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

Lets try this now:

Noname

And the result:

Noname.png

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

Noname

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

Noname.png

Using the bim6x plugin to ArchiCAD export directly to Revit

Noname.png

And the result in Revit is:

Getting there – life is good…

Touch and go

February 27, 2019

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:

Capture.png

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:

Capture

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:

Capture

This is the code behind it

Capture

Simple – but elegant – and life again is good…
