Managing Tags with Dynamo

Luke Johnson

Konrad has posted a video along with Dynamo nodes to demonstrate the management of tags based on their host type. Fire rated walls receive a certain tag, while non-fire rated receive a different one.

This is just one example showing that Dynamo isn’t just good for form creation. It has a legitimate role among the Python / Ruby / vanilla macro / API addin realm of Revit modification and customization.

Face Based, Wall Hosted Lighting fixture with nested Plan Annotation Symbol? Yes!

Luke Johnson

Very cool and advanced workaround by Jose Fandos over at Andekan:
We will route around this limitation by first inserting the annotation family into another face-based family, and using this intermediary face-based family to place the annotation the way we want into the final Lighting Fixture.

He also demonstrates that some Lighting Fixtures will display the Maintain Annotation Orientation checkbox, but some will not, and how to work around this.

Turn an ellipse into arcs for use in Revit

Luke Johnson

A few of the global Revit pros have had a crack at rationalizing an ellipse for use in Revit.  Zach Kron went conceptual, Phil Read trimmed his way around, and David Light played with circle-based segmentation.

What is my answer to this problem?  Simply don’t do it in Revit – do it in AutoCAD.  For some people, that solution may not be acceptable, and that’s ok.  I also realise that the AutoCAD haters will probably victimise me for it…oh well, do what works I say 🙂

Here is how I did it:
I make an ellipse in an AutoCAD file after setting the PELLIPSE variable to 1.  This means that AutoCAD creates the ellipse as a polyline, which means it contains arcs.  I then Import / Link this into Revit and simply ‘pick’ the arc segments to make a nice smooth elliptical form.

Here is a video:

My method is probably the easiest of the lot, but it is also probably the least ‘Revit-ee’ and the least parametric…

Wall layers and their ability to barge

Luke Johnson

There are some basic rules of Priority, that all compound structures follow, when joining together.

1) The higher priority layers always take precedent. For example, a Priority 1 layer will barge it’s way through lower priority layers in order to join up to another Priority 1 layer.

2) Lower priority layers cannot cut through higher priority layers, during the “clean up process”- they are just stopped by them.

3) The exception to both of the above are layers that fall within the Core boundaries. A priority 2 layer “within the core boundaries” will override a priority 1 later” that is situated “outside of the core boundary”.
