A WEEKEND IN UNITY

It’s no secret that Unity has been blazing a trail on the AEC front lately. One of the selling points of Unity Reflect is that it enables us to “Easily bring our Autodesk Revit, BIM 360, Navisworks, SketchUp, and Rhino models into AR/VR“. Some extremely impressive AEC apps are being developed with Unity, including real […]

REVIT FABRICATION ATTACHER ARROW

Every MEP connector in Revit has it’s own coordinate system – it’s own idea of which way is “left” and which way is “up”. In fact all 3D MEP software uses some implementation of a connector coordinate system. It’s not optional, and some do it better than others. In all Fabrication MEP products excluding Revit, […]

GETTING STARTED WITH THE CADMEP SAMPLE ADDIN

STEP 1: DISCONNECT THE NEGATIVE BATTERY TERMINAL Navigate to C:\Program Files\Autodesk\Fabrication 2021\SDK\Samples\CSharp. Right click the FabricationSample folder and select Copy. Paste this folder in a working directory somewhere, it’s nice to leave the SDK Project unaltered for later reference. STEP 2: COPY THE ADDIN BUNDLE Open the copied FabricationSample folder and navigate to the ACAD […]

COD SCRIPTING AND NULL VALUES

Recently a collogue and I were brainstorming a simple CAM script to remove Stiffeners for all Items with a Dimension named “Length”, who’s value is under 30″… (This is obviously not an all-encompassing solution. What if the Fabrication Part in question is 100″ wide? We may want Stiffeners here!) However, in many cases we spend […]

ADVENTURES IN BOUNDING BOXES

The Revit API includes Methods to retrieve Bounding Boxes of Model Elements. There is a catch however… The Bounding Boxes returned are always aligned to the default axes of the model coordinate system. This is “close enough” if the software you are engineering only needs to get within the ballpark. An “Auto Connect” software tool […]

HOW TO CLIMB A TREE

Traversing a MEP System is a difficult endeavor to say the least. This is why many of the Hanger and Spooling automation software tools we see today are unusable. We must know the structure of a Tree before we can automate things on it’s Branches. Given a Leaf at random, how do we find the […]

WHAT IS IN A NUMBER?

A Rose by any other Number would smell as sweet… Sorry Shakespeare, this is a Software Blog. Whether we are talking about Ductwork, Piping, or Walls, Doors and Windows, the “Item Number” is arguably one of the most important bits of information we can find in a Model. It’s how we identify, quantify, locate and […]
