Wall Layer Voodoo and Prompt Optimisation

I dabbled further with LLMs and prompt optimisation – Wall centre, core and face references – Promptimalising my Revit API support prompt – Generate 3D model from single 2D image... Read more →

Link Filter, Ceiling and Link Hatch Dim Voodoo

Fresh looks at dimensioning voodoo with stable representations, accessing and filtering elements in linked files, and transient graphics for jigs – Stable representation voodoo for hatch dimensions – Dimensioning hatch pattern on ceiling – Dimensioning hatch pattern in linked file – Filter elements in linked file – RubberBand jig...

Auto-Dimension Filled Region Boundary

I am back from my break and picked up the question about creating dimensions for a filled region boundary – Programmatically creating dimensions for a filled region – Coding suggestion – Final solution... Read more →

Determine Exact Opening by Demolishing

We have looked at numerous different approaches to determine wall openings in the past, so it seems pretty hard to nail down, and pretty important to solve. Now Håvard Leding of Symetri contributed yet another exciting idea which highlights a number of surprising aspects, demonstrates a further creative use case for GetDependentElements and expands on his recent RevitLookup enhancement to retrieve and snoop dependent elements – Get demolished solid – Why? – Questions...

Accessing Dimension Line Weight

Today we share a quickie from the Revit API discussion forum thread on how to access the line weight for dimension lines – I want to programmatically access a dimension line's line weight... Read more →

Rebars in Host, .NET Framework, Importance of Fuzz

Here are a couple more Revit API discussion forum threads well worth highlighting – Retrieve rebars attached to structural element – Installing the .NET framework 4.7 for Revit 2019.1 add-ins – Importance of fuzz for curtain wall dimensioning... Read more →

Rebar, Wall Centreline, Core and Grid Dimensioning

My colleague Zhong John Wu just solved a Revit API discussion forum issue on how to create dimension line for rebar. I took this as a prompt to clean out a bunch of other dimensioning related issues lurking in my infinite and growing to-do list – Create dimension line for rebar – Newly created dimensioning not displayed – Dimension leader remains visible after removal – Dimension wall centreline, centre and faces of core – Grid references for dimensioning...

Reference Intersector and Deleting Reference Planes

We already looked at deleting unnamed non-hosting reference planes back in 2012 and 2014. Some things have changed since then, and the old code requires fixing and updating. Other interesting topics also want to be mentioned – Embodyment workshop – Bös Fulen mountain hike – Using ReferenceIntersector to place lighting fixture on ceiling face – Reformat stable representation string for dimensioning – Deleting unnamed non-hosting reference planes updated...
