I am trying to make a beamer poster. I am organizing the poster in columns. In two of the columns, I would like to align some blocks half-way down the page. My current approach to this is to try to force the blocks above them to be the same height, although I am open to other suggestions. I am inserting \vboxs inside the blocks to try to set their height. This works to some extent, but is interacting with vertical padding and leads to different effective heights depending on whether the block contains text or a figure. What is the best way to get the second row of blocks to be vertically aligned?
Here is my not quite minimal example
\documentclass[]{beamer}
% Set up as beamerposter

\begin{frame}{}
\begin{columns}[T, totalwidth=\textwidth]
\begin{column}{.49\linewidth}
\vspace{\yfudge}
\vbox to \colheightb{%
\begin{block}{Section}
\vbox to \blockheight{
The block containing text is a little bit taller, and also the vertical padding between the title and the text is reduced (eliminated?).
}
\end{block}
\begin{block}{Section}
\end{block}
\vfill
}
\end{column}
\begin{column}{.49\linewidth}
\vspace{\yfudge}
\vbox to \colheightb{%
\begin{block}{Section}
\vbox to \blockheight{

\end{beamercolorbox}
}
% no navigation on a poster
\setbeamertemplate{navigation symbols}{}
% Use rounded blocks
%\setbeamertemplate{blocks}[rounded]
% Larger titles for the block
\makeatletter
\newcommand\semiHuge{\@setfontsize\semiHuge{45}{40}}
\makeatother
\setbeamerfont*{block title}{family=\sffamily,series=\bfseries,size=\semiHuge}
Edit: Update: I was able to finish my poster by manually adjusting the block heights until they approximately matched. This is not a solution, but it will have to do.
Edit: stacking column environments doesn't work as needed
It was suggested that proper vertical alignment could be achieved by stacking two column environments. This works if there are only two columns, but my use case is more complex, which wasn't reflected in the previous minimal example. I have created a new minimal example illustrating why the column alignment approach isn't suitable here, as it would require nesting column environments which creates new vertical alignment issues at the top.

Best Answer
Here's a suggestion using minipages instead of the column environment. The good thing with minipages is that you can specify the height. The vertical alignment is done with
\hfill.The command is
\begin{minipage}[alignment][HEIGHT][alignment]{WIDTH}...\end{minipage}The text and figures seem to align fine now but please let me know if it doesn't work as you want it to.
I also created a new environment (called MRuleBlock) that might simplify your code. The code generates two slides, one without the new environment and one with.
Code:
Which gives:
You can obviously play around with the parameters
\blockheightand\blockwidthto fine tune the blocks.
