Room for improvement…

An interesting challenge came up yesterday: a client, architect, has a model that the MEP engineer uses as a link for his model. Hurrah, finally an integrated BIM. Now the problem arose that the MEP engineer needs his spaces that he derives from the architects model disregard any suspended ceiling as room boundary for his calculations, whereas the architect needs the correct room volume and therefore the ceilings act as room boundary.

That’s what the architect needs:

noname

But that’s what the engineer needs:

noname

Solution: we make the ceilings non room bounding, then analyze the ceiling height and set the upper limit offset for the rooms in the architects model accordingly.

Dynamo to the rescue:

capture

And the result in the architectural model is:

noname

You might have noted that we only use Get/Set BuiltIn Parameter nodes – the reason for that is the fact that when running of different languages these parameter names change, but the built in parameter definition stays the same.

This might come in as a game changer – significant – https://www.opendesign.com/products/teigha-bim

Workflow magic

Needed too figure out a workflow for mechanical engineering and structure – here’s the model with ducts as links

Here’s a Dynamo graph

We want to create intersection Boxes with an offset from the ducts – here we specify the offset

And the result after running the graph

Red boxes indicate the relevant openings in the walls required… simple…

Join together – but beware to do it in a detached way

I really just wanted to quickly finish up a job for Monday so that I might do nothing but get rid of my cold tomorrow and – alas – I stumbled upon something potentially unsafe.

The following picture looks harmless but take a look at the spot elevations:

noname

We have one tag for a beam that says top is at 0.00 and bottom is at -0.94.

Then a spot elevation for the adjacent slab top -0.14 bottom -0.34

Then another spot elevation for the beam tagged that says top -0.34 bottom -0.94

Then another spot elevation for the beam at the bottom with top -0.35 bottom -0.94

Huh?!?

Let’s take a look at this in section

noname

 

So we have a slab (blue outline), a beam (red outline) joined to the slab and another beam (green outline) joined to the red beam.

Clearly both the tag and the spot elevation on the beam in floor plan are wrong because its top is at -0.14

Switching join order – no change

Red beam is modeled with a z-Offset of -0.14 – let’s change that to 0.0 and take a start and end offset of -0.14

4 Warnings

noname

But the result looks OK

noname

So lets take a look at the tags

noname

Interesting change tag right, spot elevation still wrong

Lets tag the green beam

noname

Here the spot elevation is right, the tag is wrong (and sure the parameter values are as well)

noname

Then, after detaching it from its plane, putting the z-Offset to 0.0 and the start and end offset to -0.35

noname

Great – 2 tags and 3 spot elevations and 4 right out of 5… and if that goes to site for construction I’ll have a list of angry calls at 6:00 AM…

What do we learn – Trust is good, but control is better

Updates..

Just an update on an older post since we needed to exchange some graphics and replace them – quick Keyshot render (I think I mentioned that I like their stuff)

2-3

All for today

A picture says more than thousand words

Coordination reports in Revit are boring – running through this report and looking at the ID numbers isn’t really thrilling…

noname

I’d like to see the this in the model, with some color to quickly identify the elements we need to look at…

Something like this – pardon the simplicity of the project sample:

noname

Well, the video below shows how to do this

Revizto

It does not happen too often, but once in a while we do endorse stuff. This time, Revizto.

From our nice Revit Model to Revizto in four clicks

A little bit of tweaking

noname

We can look at the sheets in the context of the model

noname

And finally we can export a standalone EXE file that we can give our client to play with. Or host it in the cloud.

Quick.

Easy.

I like that.
