It does not have to be an overwhelming project to start moving to National CAD Standard (AIA) layer names as shipped with AutoCAD Civil 3D. The rules can be simplified, and with a few core abbreviations, you can get most of your work done at least in the spirit of NCS/AIA.

The Civil 3D Output ribbon provides an Export to HEC-RAS button, and HEC-RAS provides an Import Geometry Data tool. But getting river direction, river stations, and cross section stations transferred right is not as easy or as obvious as it could be. This is a method to export as obviously as possible from Civil 3D and use two simple commands in HEC-RAS to fix the data.

I found many help documents to set up Git mergetool and difftool for KDiff3 on Windows. But none of them was quite right for my Windows 10 and Git 2.6.2.windows.1.

I seem to have bad luck with refrigerator/freezer drain lines. Or maybe I just keep my freezer too cold. In any case, I now have had to thaw the drain line in the freezer at two different homes in one year.

Mark your calendar now. If you don't have freedom from hemorrhoid pain and the beginning of permanent healing in three days, we need to talk. All you need to do is push less and pull more for the rest of your life--starting right now. And for the rest of today and the next three days, you need to study, ponder, and explore all the nuances, aspects, implications, meanings, feelings, costs, rewards, and discoveries of pushing less and pulling more.

Today I sent my first War Tax Resistance letter to the IRS as coordinated by the National War Tax Resistance Coordinating Committee. As explained below, this is neither a money-saving scheme nor a get-out-of-jail-free scheme.

To do a Riprap Filter Design with the FHWA Hydraulic Toolbox, you need to understand the underlying criteria the program uses to accept or reject a filter design. The criteria are taken from National Cooperative Highway Research Program Report 568: Riprap Design Criteria, Recommended Specifications, and Quality Control. Section 3.2.2, pages 62 and 63.

In August 2014 FHWA released version 4.2 of their Hydraulic Toolbox, which is a bundle of calculators for the venerable Hydraulic Engineering Circular No. 15 Design of Roadside Channels with Flexible Linings aka HEC-15. I confess that despite my 20+ years of civil engineering,this software is news to me. While some of its calculators may be trivial to any given civil engineer, others may be a big help. And they all are packaged neatly in a Windows program that can output a PDF or RTF report.

In his State of the Union Address this week, President Obama said, "And to everyone in this Congress who still refuses to raise the minimum wage, I say this: If you truly believe you could work full-time and support a family on less than $15,000 a year, try it. If not, vote to give millions of the hardest-working people in America a raise." But is the minimum wage really about heads of household? Who earns minimum wage?

One of the hardest issues of using AutoCAD for new users is controlling text heights. And one of the most common issues people have with Geotables curve, line, and point tables is getting the blocks to insert at the scale they want. I will give first in this post the short fix answers. Then I will explain what is going on. If you don't want to do the first quick fix and you don't want to read the long explanation, just skip to the Other Fixes section at the bottom.
I have been in AutoCAD customization mode a bit lately. Today I worked on a cool Free Libre Open Software program I was paid to write by M2Group of Mesa, Arizona back in 2004 to create automated curve data tables (now also line and point data tables). It's called Geotables, and it is one of my more well-written programs since it was written from scratch with the intent for it to be open source. There's a pretty good brochure for it at the Wikia AutoCAD Wiki. Anyway, I thought I might write a bit about it today partly to publicize that it is still very much viable and supported as well as to discuss a bit more what it does.
