After learning the basics of threejs for the about page, I set out to develop a web based concrete design tool. A video of https://www.re-tug.com/concretedesign/ in action is below:

The Functionality
I set out to make a easy to use interface …
A co-worker of mine asked if I could find a way to check min. joist bearing lengths after being burned on a recent project where they had a few beams that worked for strength and deflection, but did not match SJI's minimum flange dimensions for bearing.

With a desire to update my "about" page, I set out to kill two birds with one stone, a fresh new about page and learning 3d graphics in the browser. https://www.re-tug.com/about/ is built with three.js, a package built within Javascript to make 3d graphics.
…Above is my first functional C# revit add-in, making bending rebar at any angle an easy task. For those non-structural engineers, the smaller the piece of rebar, the smaller the allowable bend. Being able to quickly sketch rebar to scale with minimum bend radii is …
Making a revit addin has been a goal of mine for some time. Yesterday I finally succeeded, complete with ridiculous names, images and tasks completed.
The addin is simple and essentially useless, it assigns walls of a certain type to a workset (Github).

@Toni, this post does not discuss the level of mesh refinement required. The focus is on building an ETABS model efficiently. Mesh refinement is typically evaluated within ETABS by studying the parameter of interest and refining the mesh until the results converge to an acceptable tolerance.
@fpsstructures, I edited your …

Really impressive work combining Three.js with ETABS for a parametric workflow. The ability to quickly generate and analyze multiple tower forms can be a huge advantage during early-stage design exploration. I also like how the structural logic still feels clean and efficient despite the complex geometry.

How do you assess the fineness of the mesh required? More scale or load based?
