Doing some cool stuff with JavaScript in Bluebeam (Part 2)

In part 1 we added a single line of JavaScript, it was basic. But hopefully that single line of JavaScript provided some inspiration on how you could make other stamps you might create dynamic, and less specific.

In this post we’ll do another example, but this time I’ll show you how to use some data input by the user when you place a stamp to do some calculations using JavaScript.

Drawing Reinforcement in Excel…Really (Part 3)

In Part 2 we covered the functions for creating coordinates for accurately representing shear reinforcement (stirrups and links) using an XY scatter chart in Excel.

In this third and final part, we’ll cover the functions for outputting the minimum lengths of stirrups or links. As mentioned in the first part in this series, estimating the total length of bars and hence weights can be a tedious boring process. These functions take out boring bits, but it’s still not ‘exciting’.

Drawing Reinforcement in Excel…Really (Part 1)

One thing that irks me about a lot of spreadsheets I’ve seen created over the years is the fact that the inputs for something that can be visualised are hidden behind a few numbers in cells. No visual representations of the calculations are given. With an overarching reliance on the user to mentally complete the picture of their design inputs (and sometimes outputs) within their minds.

To minimum or not to minimum, that is the question?

Minimum steel, love it or hate it, we have minimums for a reason even if it seems like overkill sometimes given that we may have very low demands.

This post will demonstrate why (I hope) we are required to comply with these arbitrary limits. Usually I’m going into these posts with only the theoretical background of why something exists, but hopefully once we get into it this theory can actually be demonstrated.

Using Mathematica to save the world

Well, one person’s world of torsion anyway…

In this post I’ll show how to use Mathematica to check some derivatives of torsion relationships.

Mathematica is an analysis/computational tool by Wolfram. Now if you had to pony up the dollars for it you’d be out a few thousand dollars, but as it happens I’m cheap and it’s free on Raspberry Pi’s Raspbian operating system. Yes it’s linux based, but don’t let that turn you off, it’s so simple to setup anyone could do it.
