Using PyXLL, I have programmed automatic shapes in Excel. That is, I built a function that draws an arbitrary shape in a user spreadsheet: the shape is defined by a range of coordinates; as the coordinates are edited, a new shape can be drawn.

  • 0 Comments

I developed a Python function to calculate closed form exact values for wind forces and wind CGs.

I use only calculus — no bar charts with 0′ to 15′, 20′ to 25′, et cetera —- a curve rather than a step function. I present derivations and examples.
